2006-2011 Mercedes-Benz ML350 / ML500 / ML550 / ML63 (W164) CCB Big Brake Kit — Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper Front + Genuine AP Racing CP9541 Radi-CAL II 4-Piston Caliper Rear Setup
The W164 ML350, ML500, ML550, and ML63 AMG are heavy AWD SUVs, so repeated high-speed stops can push the factory iron brakes into heat, dust, and rotor-wear problems faster than a lighter sedan. This StopFlex kit replaces the factory brake package with 380mm carbon-ceramic rotors, a Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper in front, and a Genuine AP Racing CP9541 Radi-CAL II 4-Piston Caliper in the rear. Each kit is engineered to the buyer’s exact W164 trim so the brackets, rotor-hat offsets, caliper position, and wheel clearance are matched to the vehicle being built.
- 380mm carbon-ceramic rotors are used at both axles, so the kit requires 19 inch or larger wheels and still needs spoke-clearance verification.
- The front axle uses the Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper to increase thermal capacity and pedal consistency over repeated stops in a heavy W164 SUV.
- ML63 AMG and standard ML350/ML500/ML550 W164 trims can differ in brake packaging and hub/upright details, so StopFlex builds brackets and hat offsets for the confirmed trim rather than assuming one W164 fitment.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses the Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper, pairing six-piston clamping with a 380mm carbon-ceramic rotor for more stable pressure distribution across the pad. AP Racing is a known motorsport brake manufacturer, and the Radi-CAL II architecture is selected here for a rigid, lightweight performance-caliper package rather than a cosmetic caliper cover or generic casting.
Rear Caliper (Balance)
The rear axle uses the Genuine AP Racing CP9541 Radi-CAL II 4-Piston Caliper with a matching 380mm carbon-ceramic rotor. Its role is to keep rear brake contribution controlled and predictable so the W164 remains stable under hard braking instead of relying on an oversized front-only conversion.
Front & rear, engineered together: This kit is engineered as a front-and-rear system, so piston area, rotor diameter, hat offset, and caliper placement are specified together for the exact ML trim. That avoids the common front-only problem of adding front torque and heat capacity without matching rear response, pedal travel, and ABS behavior.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
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.

FAQ
Will this fit my exact W164 ML350, ML500, ML550, or ML63 AMG?
StopFlex does not treat every W164 as the same brake package. Before production, the kit is specified to your exact model year, trim, hub/upright layout, rotor-hat offset requirement, and wheel clearance, including the differences between ML63 AMG and standard ML trims.
What wheel size is required for the 380mm kit?
The 380mm front and rear rotors require 19 inch or larger wheels. Wheel diameter alone is not enough; StopFlex also checks spoke clearance against the Genuine AP Racing CP9560 front caliper and CP9541 rear caliper before confirming the build.
Will the parking brake still work?
Yes, the kit is designed around the W164’s factory-style foot-operated/cable parking brake arrangement. This chassis does not use an electric caliper-mounted EPB, so rear fitment is handled around the mechanical parking-brake hardware rather than an EPB motor.
Why choose carbon-ceramic over replacement iron rotors on this ML?
Carbon-ceramic rotors reduce rotating and unsprung mass, cut brake dust, resist corrosion, and maintain more consistent performance when a heavy W164 SUV is braked repeatedly from highway or mountain-road speeds. The payoff is strongest for owners who are tired of iron rotor dust, heat checking, vibration, or short service life.
