Brakes

By Richard Fong

Upgrading brake pads and rotors can make considerable improvements to a vehicle’s braking system, especially since the factory equipment is generally adequate for an everyday street application but not always ideal for high-performance driving. However, there are a few other variables that can further enhance the performance of a factory brake system before making the jump to aftermarket calipers and larger rotors. Now that you’ve been familiarized with some of the first and most straightforward brake-system upgrades in our Brake Systems 101: Pads and Rotors, it’s time to look at the next modifications in line to optimize the factory brake system. Two-piece rotors, performance fluids and braided brake lines can further improve your factory brake system for greater performance on both the street and the track.

Room to Expand

A smoothly-operating vehicle typically indicates that all is well and functioning properly. When an ABS-like vibration feeds back through the brake pedal, it can be disconcerting to some and annoying to others. It’s certainly an indication of something amiss that requires attention. That vibration could simply be caused by uneven pad material built up on the surface of the rotor, for which a proper brake service (new pads, resurfaced or replaced rotors, brake fluid flush) would remedy. However, in the case of performance and heavy utility applications, the damage to the rotors could be more severe.

Dissipating Heat

A vast majority of brake rotors on the market are manufactured as a single piece of iron for cost and durability. As the friction surface for the pads, rotors are subjected to extreme heating and cooling cycles. Since the center or “hat” of the rotor bolts to the wheel hub, it is sandwiched between the hub and the mounting pad of the wheel. This limits the rotor’s ability to expand and contract freely when subjected to extreme braking conditions (as would be the case on a racetrack or during an aggressive mountain drive) and could lead to warped rotors. A viable solution would be to upgrade to a 2-piece rotor solution. In this application, a billet aluminum hat is fastened by way of “floating” hardware to a rotor, which permits the rotor to expand, contract and dissipate heat without being restricted by the hat. A 2-piece solution also permits the use of exotic and lightweight rotor materials as well, like a carbon-ceramic matrix.  An added benefit to having a billet aluminum hat and/or lighter rotors is reduced unsprung weight. This weight reduction helps to sharpen and lighten steering response which further lends to improved handling.

Boiling Point

A recurring theme in brake systems is that heat is the enemy. For the most part, this is true, the exception being specialized brake pad compounds formulated to function optimally at higher temperatures (racing brake pads). Aside from this instance, heat that is generated by the friction between the rotors and the pad material eventually transfers to the calipers and then the brake fluid. Modern brake systems are hydraulic, which means that they rely on incompressible hydraulic fluid (in this instance, brake fluid) to actuate the pistons against the pads when the brake pedal is depressed. The Department of Transportation (DOT) has established standards to indicate a fluid’s capabilities. DOT 3 brake fluid is the most common fluid used in automobiles. The name denotes the fluid’s heat capacity and performance capability as required by the DOT. Street vehicles rarely exceed the capabilities of DOT 3 fluid under normal driving conditions. When brake fluid heats to the point of boiling, pockets of air form in the brake lines. These compressible voids translate into a spongy brake pedal and an unresponsive brake system with dramatically reduced stopping ability. If you’ve upgraded your pads and rotors and have not upgraded the brake fluid, this could be the cause of poor braking performance. The solution is to upgrade your brake fluid. Under performance conditions such as on a track or a road requiring significant and frequent brake input, upgrading to DOT 4, DOT 5 or DOT 5.1 brake fluid will help to maintain the responsiveness and effectiveness of the brake’s hydraulic system.

3R1A9615 Edited 2

DOT Standards

Typical factory brake fluid is engineered to function within a prescribed temperature range optimized for the majority of driving conditions that the manufacturer expects a vehicle to encounter. This covers a broad spectrum of conditions ranging from freezing to triple-digit ambient temperatures. While these requirements cover a seemingly broad range of temperatures, the brake fluid must endure far more extreme temperatures. DOT 3 fluid is the most common fluid type employed by automakers with some requiring DOT4 fluid (in the case of higher performance or heavy duty applications). DOT 3, 4 and 5.1 are polyethylene glycol based fluids while DOT 5 is silicone based. The hygroscopic traits (propensity to absorb moisture from the atmosphere) of the DOT 3, 4 and 5.1 fluids could render the fluids less effective over time. Regular flushing of the brake system mitigates this effect. The silicone-based DOT 5 fluid tends to cost more but benefits from its hydrophobic properties.

Containing the Pressure

Another component of a factory brake system that could benefit from improvement is the brake line. The stock brake lines are often high-pressure rubber hoses designed to be flexible throughout the full range of travel for your suspension. However, during high performance braking, these factory lines tend to expand under extreme pressure, resulting in reduced responsiveness and braking performance along with a spongy brake pedal. To improve the responsiveness of the brake system hydraulics, swapping out the factory brake lines with performance brake lines is an essential upgrade. Performance brake lines (like those offered by Goodridge) feature a PTFE liner (inner hose) that is shrouded by a flexible sheathing (stainless steel or even exotic materials like Kevlar) that protect the liner and prevent expansion. This keeps the fluids moving toward the calipers, for more responsive braking under all driving conditions.

In our next installment of STILLEN University, we’re going to explore big brake system upgrades in greater detail. Check back with us soon!

If you would like to shop for upgraded 2-piece rotors, brake lines, or brake fluid:

You might be wondering… When it’s time to replace your brake rotors, should you upgrade your brake rotors or just replace them with identical OEM rotors? One tip the STILLEN brake experts offer: consider how you use your car.

Is it a daily driver used for commuting and errands? Are you an enthusiast who lives for the open road and canyon carving? Or maybe you participate in autocross or track days.

Regardless, there are many choices in rotors, and one way to shop for replacement brake rotors, as well as brake pads and brake fluid is with a Good- Better – Best approach.

For more info about this approach, check out this how-to video from STILLEN expert Mark.

 

Brake Rotor Upgrade Level: GOOD

Drivers seeking a good rotor that offers a performance and durability upgrade from OEM rotors should consider upgrading to STILLEN OEM replacement brake rotors.  They are well suited for aggressive driving and the occasional track day.

Features include straight cut vanes, zinc coating, chamfered slots and precision ground friction surfaces.  Multiple machining options are available, from slotted to cross drilled to the popular hook slot hybrid finish.

Available for virtually any passenger vehicle on the road today, STILLEN sport rotors are proudly Made in USA.

Brake Rotor Upgrade Level: BETTER

For hard core enthusiasts and track day fans concerned with high temperature heat management, a better option might be the DBA 4000 series brake rotors. These discs offer more sophisticated metallurgy for longer life.

They also feature DBA Kangaroo Paw vane technology. These vanes are multi-directional, meaning they draw cooling air in from any direction.

This improves heat dissipation and also permits the rotors to be mounted on both driver and passenger side hubs. Another stylish touch is the available gold rotor vanes and hats.

Brake Rotor Upgrade Level:  BEST

The ultimate brake rotor upgrade could be the DBA 5000 series.  Suitable for frequent track use, these rotors offer the Kangaroo paw vane technology and improved metallurgy of the 4000 series, but add a two piece design.

The rotor hat is a separate assembly that is bolted to the brake rotor. This helps isolate the wheel hub bearings from excess heat, reduces brake vibration caused by rotor warping under heavy use, and offers weight savings as well.

One indicator the DBA 5000 series are meant for serious drivers is the brake temperature paint applied to the rotor edges. These indicators help drivers ascertain the temperature range their brake system is operating in.

This in turn helps determine proper brake pad and brake fluid selection for track use.

Brake Pad Replacement and Upgrades

It’s always advisable to replace brake pads when mounting new rotors. STILLEN Metal Matrix brake pads offer a nice blend of bite and power along with reduced dust and noise. This makes them ideal for street and occasional track use.

Other brake pads might be better suited for full-on track use, such as the Hawk HPS 5.0s or Ferodo DS2500 HP.

Brake Fluid Replacement

When you’re considering brake system upgrades, it’s essential to include brake fluid replacement in the thought process.

One popular opinion is that it’s best to upgrade to racing brake fluid.

As STILLEN brake expert and all-around good guy Mark explains, this is a common misconception.

While your OEM brake fluid does have a limited heat capacity, so does your OEM brake system. Upgrading your rotors and pads does give you a higher threshold, but your calipers still have a limit.

If you upgrade your brake fluid past what the calipers can handle, you could exceed your brake systems operating envelope without knowing it. Should it occur, brake fluid boiling is an indicator that your brake system is overheating.

Going with a little bit of an upgrade is fine, but you don’t need to go with a full-on race brake fluid.

While shooting the how to video for brake upgrades, Mark installed the DBA 4000 series rotors and STILLEN Metal Matrix brake pads on his Subaru BRZ and had the following to report:

“After we finished the install on the brakes, we moved onto the bed-in procedure then onto our test drive and you could really feel the difference. Our stopping distances were much shorter, our initial bite was much better and brake fade was much less apparent as the brakes heated up so this is an awesome upgrade for the BRZ or for any vehicle. You can really improve your driving experience.”

It’s that time of year again.. thousands are burning up the 30+ miles worth of carpeted aisles at the infamous SEMA Show in Las Vegas!  The STILLEN Team is no exception, with a big booth introducing the world to the new AP Racing Radi-CAL line of calipers used in the STILLEN-engineered Big Brake Kits.

AP Racing Radi-CAL Brake Caliper Launch at SEMA with STILLEN

These new Radi-CAL road calipers get there heritage from the racing Radi-CAL high performance calipers launched in motorsports in 2007, which have been dominating the likes of F1, F3, NASCAR and countless others.  This new caliper design features a 2-piece aluminum body with H-structure, and a non-symmetrical design developed to have a large reduction in mass yet improved resistance to braking torque.  Another benefit is increased caliper cooling surface without decreasing structural rigidity.

AP Racing Radi-Cal By STILLEN with Black Caliper

STILLEN has developed applications for many popular setups, which are listed below, and have plans to continue to grow the line.

We will be releasing much more information as we return from SEMA, and the response has already been overwhelming at it’s introduction!

When nothing but the best will do, serious customers look to AP Racing and STILLEN.

GTR Brakes

STILLEN Announces CCM-X – The next generation of Carbon-Ceramic Matrix Brakes for the Nissan R35 GT-R

The STILLEN R&D team continues to develop industry-leading performance products with long-standing technical partner AP Racing. Their hard work has resulted in the release of the next generation in Carbon-Ceramic Matrix (CCM-X) brakes for the Nissan GTR. This kit utilizes a new High Thermal Capacity (HTC) process which helps pull the heat from the CCM disc surface deeper into the 3D core to allow the discs to operate cooler through more efficient use of internal venting and air flow.

We have also homologated a new Pagid RSX1 pad material designed specifically for our new CCM-X discs for easier bedding and higher performance, these pads are ideal for use on the street and for track days.

The CCM-X disc assembly hardware has now been updated to include anti-rattle springs that still allow the full benefit of a floating disc, yet eliminates the “noise” associated with this style of disc.

During extreme performance testing at Auto Club Raceway in Fontana, CA, performing back-to-back repetitive testing runs pushing the limits of brake temperatures, the new combination of HTC CCM-X discs and Pagid RSX1 pad material reduced disc temperatures from an average of 1488F to 1346F, that’s 142 degrees cooler than the previous generation CCM. These real-world tests confirmed the results of our brake dyno testing at AP Racings lab in Coventry, England.

Once found only on the world’s most expensive supercars, Carbon-Ceramic Matrix (CCM) brakes have been developed for the first specifically-tuned aftermarket application – the Nissan R35 GT-R. These 400mm disc assemblies are larger than the standard OE iron discs, yet reduce weight by nearly half. This is rotating and unsprung weight, leading to improvements in all performance categories: acceleration, handling and braking.

After three decades of using carbon-carbon brakes on racing vehicles (even longer on fighter jets), AP Racing CCM discs are the next technological platform. Advancements in materials, process technologies and nanoparticle technology make it possible to use a special carbon fiber precursor along with new, patented process techniques. The unidirectional precursor is needled into a 3-Dimensional, continuous carbon fiber preform. This differs from lower cost technologies that use loose, chopped strand fibers and thin woven face plies bonded on as a friction surface. A true 3D matrix is stronger, more robust and provides longer life than the more brittle alternative. As a comparison, think quality hardwood versus particle board or MDF with a veneer.

Converting the 3D preform to carbon-carbon is done under high heat and pressure via methane cracking during a special carbon vapor infiltration (CVI) process. After initial machine work, a final conversion process results in a full matrix carbon-silicon carbide (CSiC). We call it Carbon-Ceramic Matrix, or CCM for short. The discs are then sent through the final machining, grinding, and balancing. Of course, the CCM discs are now so hard that only special diamond tooling can be used!

Who uses these ultimate CCM discs? The most up-to-date version is found on the Koenigsegg CCX and McLaren MP4-12C. And now – STILLEN and AP Racing have optimized a specific set for your R35 GT-R and its factory brake calipers.

The STILLEN-AP Racing CCM-X brake upgrade kit includes:

  • Front & Rear CCM-X brake disc/hat assemblies
  • Front & Rear Pagid RSX1 street & track use brake pads
  • Caliper spacers
  • Active brake cooling package required by Track Users (Not Shown – Sold separately and can also be used with Iron Rotors)

Note: Due to the dramatic reduction in overall mass, brake temperatures will run higher than the O.E. iron disc system given the same usage. STILLEN strongly recommends using AP Racing PRF brake fluid, one of the best high temperature fluids available. PRF is used in the most demanding Motorsports applications around the world.

We recently worked with Truckin’ Magazine on some high speed brake testing, putting the AP Racing BBK designed by STILLEN to the ultimate test at El Toro Marine Base.

Truckin’ editor Dan Ward pushed their 2004 GMC Sierra “Project Novakane” to the limit with repeated 80-0 mph stops beginning with the factory setup, swapped brake systems, and repeated the aggressive testing on the truck after outfitting the AP Racing setup onto the truck.

Below is an excert from the article with performance data from their extensive testing:

Truckin’ Magazine – October 2010 Issue

“Rather than test the truck from 60 mph, we hit the ‘whoa’ pedal at 80 mph, after all, do you really drive 60 mph on the freeway? Factory braking performance was dreadful, as a combination of grooved rotors and newish pads made for chassis vibrations when stopping and a weak pedal. After bolting on the 20-inch wheels and tires to the Sierra, the sticky Nitto tires actually improved the stopping distances, which confused us at first, but then we released the overall weight of the new wheels and tires wasn’t much heavier than our OE combo.

GM touted the redesigned ’99+ fullsize trucks as having the best brakes in their long history of building trucks. That’s nice marketing hype, but GPS data acquisition doesn’t lie and the new AP Racing brakes are the double-D cups to the OE’s training bra. We weren’t surprised to have better overall stopping power, after all, that’s what we expected from a company with a rich racing heritage, but what did surprise us was the pedal feel. Without being touchy, the brake pedal is now very linear with minimal inputs doing an impressive job of bringing the 4,300-pound truck to a standstill. As expected, the aggressive brake pads are heavy on the dust, which provides us another excuse to wash the wheels/tires more often. This upgrade was expensive, but unlike in many cases, you actually get what you pay for from Stillen.

With the AP kit bolted on, we made several 80-0 mph test runs and came away with an average of 226 ft, more than 144 ft than better than stock. That’s equivalent to stopping in only 5.56 school buses or basically stopping before going through an entire intersection and saving the lives of more than 350 kids in those buses.

Also, the green AP heat paint that was applied to the stock rotors burned white, meaning they exceeded 430 degrees Celcius during hard braking, but the new AP rotors didn’t burn through the green paint. This translates into the drilled holes and vents doing their job by keeping the rotor surface cooler, longer. If safety and performance are high on your list, bringing your truck to an immediate halt doesn’t get much better than with AP Racing’s bolt-on big brakes.”
