2006-2011 Mercedes-Benz ML350 / ML500 / ML550 / ML63 (W164) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
The W164 ML is heavy enough to expose factory iron-rotor heat, dust, and pad-transfer issues in mountain driving, towing, and repeated high-speed stops. This StopFlex kit uses 380 mm carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-piston front options and matched 380 mm rear 4-piston options to add thermal capacity while reducing rotating and unsprung mass versus comparable iron hardware. Each kit is built for the confirmed ML350, ML500, ML550, or ML63 AMG configuration, because the AMG and non-AMG W164 trims can require different bracket geometry, rotor-hat offsets, and wheel-clearance checks.
- 380 mm front and rear carbon-ceramic rotors require 19-inch or larger wheels; barrel and spoke clearance are confirmed before production.
- Front choices are Brembo V6, GT6, or GTS6 6-piston calipers on a 380 mm rotor, giving the W164 ML a larger heat sink than a stock-style iron service replacement.
- The ML63 AMG and standard ML350 / ML500 / ML550 share the W164 chassis code but are not treated as one fitment; StopFlex engineers the brackets and hat offsets to the buyer’s exact trim.

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)
Front braking is handled by Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, selected to match the buyer’s budget, finish, and intended use. The V6 option uses a Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper with a 380 mm rotor, the GT6 uses a Genuine Brembo GT | M6 6-Piston Caliper with a 380 mm rotor, and the GTS6 uses a Genuine Brembo GT | S6 6-Piston Caliper with a 380 mm rotor. The fixed 6-piston layout spreads clamping load across the pad face for firmer pedal response and more consistent pressure distribution than the W164’s factory sliding-caliper-style service architecture on non-AMG trims.
Rear Caliper (Balance)
Rear braking uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with 380 mm carbon-ceramic rotors to support front-to-rear brake balance under heavy deceleration. Because the W164 uses a mechanical drum-in-hat parking brake, the rear package is engineered around the vehicle’s parking-brake hardware rather than an electronic parking-brake motor.
Front & rear, engineered together: A 380 mm front-only upgrade can shift torque capacity forward and leave rear thermal capacity behind on a heavy SUV. StopFlex engineers the front and rear rotor hats, caliper brackets, pad compounds, and line package as one system so the ML350, ML500, ML550, or ML63 receives trim-specific brake balance instead of a platform-wide caliper swap.
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 kit fit my exact W164 ML350, ML500, ML550, or ML63 AMG?
Fitment is confirmed against the exact trim before the kit is built. StopFlex does not treat every W164 as the same car; brackets, rotor-hat offsets, and caliper mounting are matched to the confirmed ML350, ML500, ML550, or ML63 AMG configuration.
What wheel size is required for the 380 mm carbon-ceramic rotors?
The 380 mm rotor package requires 19-inch or larger wheels. Wheel diameter alone is not enough; StopFlex also checks spoke clearance against the Brembo 6-piston front caliper before production.
Will the parking brake still work after the rear caliper upgrade?
Yes, the kit is engineered around the W164’s mechanical drum-in-hat parking brake layout. This chassis does not use an EPB motor on the rear caliper, so parking-brake function depends on preserving the cable-actuated rear shoe system inside the rotor hat.
Why choose carbon-ceramic instead of replacement iron brakes on this ML?
Carbon-ceramic rotors reduce brake dust, resist heat-related fade, and cut rotating mass compared with similarly sized iron rotors. On a heavy W164 SUV, that matters most during repeated highway-speed stops, mountain descents, towing use, and owners who want less front-wheel brake dust.
