Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2006-2011 Mercedes-Benz ML-Class / AMG (W164). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2006-2011 | Alcon RC6 6-Piston Caliper / 380mm | Alcon RC4 4-Piston Caliper / 380mm | 19" |
Every StopFlex kit is bespoke-engineered for your exact model and trim — brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, never assumed from the platform. Trims that share a chassis name can differ mechanically: a pure performance variant often carries different knuckles, hub geometry, and wheel ET clearance than the standard models, so parts that bolt onto one are not the parts that fit the other. Calipers, pads, rotor hats, floating hardware, and brake lines ship as one matched system built to your confirmed trim. Modified knuckles, uprights, or non-factory suspension mounting points must be reviewed before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Winter & Cold-Weather Braking
Winter question, straight answer: untuned ceramic discs bite less when cold. StopFlex optimized the pad compound and the rotor's ceramic coating for cold operation, so cold-start braking in winter feels very close to warm-weather braking. Extra following distance on freezing first stops is still smart; severe-winter daily cars should run Street Spec.
Caliper Overview
Front Caliper
The front runs the Alcon RC6, a 6-piston monobloc caliper clamping a 380mm carbon-ceramic rotor. Six pistons spread clamp load evenly across the pad face, which keeps pedal feel firm and repeatable when this 5,000-plus-pound SUV is loaded and hot.
Rear Caliper
The rear uses the Alcon RC4, a 4-piston caliper on a 380mm rotor. It adds rear thermal capacity so the truck's weight bias doesn't cook the front axle during repeated stops, and the parking-brake function is retained to match your car.
Choose Your Rotor: Street, Track-Day, or Motorsport
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.

FAQ
Will this kit fit my exact W164, or is it a generic platform kit?
It is built for your confirmed trim, not the platform. The ML63 AMG uses different front knuckles, hub geometry, and wheel clearance than an ML350 or ML550, so we set the brackets, caliper mounting, and rotor-hat offsets to your specific car after you confirm year and trim. We do not sell this as a one-size W164 bolt-on.
What wheel size do I need to clear the 380mm rotors?
The 380mm front and rear rotors require a minimum 19-inch wheel. Wheels under 19 inches will not clear the RC6 front caliper, and spoke shape matters too—narrow or deep-dish spokes can foul the caliper body even at 19 inches. Send us your wheel details and we'll confirm clearance before you buy.
How do these carbon-ceramic brakes behave in winter on a cold start?
A cold carbon-ceramic disc naturally bites a little less than cold iron on the first stops—that's physics, not a fault. We tune both the pad compound and the disc's ceramic coating for cold engagement, so cold-car feel on the W164 comes very close to summer feel. Still leave a little extra following distance on your first stops on the coldest mornings.
My factory ML brakes feel undersized for the truck's weight—will this fix that?
That's the most common W164 complaint, especially on cars with big aftermarket wheels. The 380mm carbon-ceramic rotors with the RC6 front and RC4 rear give far more thermal headroom than the OE setup, so the brakes handle this SUV's mass and heavy repeated stops without the fade owners describe. The pad compound holds friction near 0.44 and resists fade to about 750 °C.
