2007-2013 Mercedes-Benz S350 / S400 / S500 / S550 / S600 / S63 / S65 (W221/V221) CCB Big Brake Kit — Genuine OEM AMG 6-Piston Caliper Front + Genuine OEM AMG EPB Single-Piston Caliper Rear Setup
The W221/V221 S-Class is a heavy luxury sedan, and repeated high-speed braking can expose the limits of iron rotors through heat, dust, and front-end mass. This StopFlex kit pairs a Genuine OEM AMG 6-Piston Caliper with a 400mm front carbon-ceramic rotor and a 380mm EPB rear package to add thermal capacity, reduce brake dust, and cut rotating unsprung weight. Each kit is built to the confirmed S350, S400, S500, S550, S600, S63, or S65 configuration, because AMG and non-AMG W221/V221 trims can differ in mounting geometry and wheel clearance.
- 400mm front carbon-ceramic rotors require 20-inch or larger wheels; wheels under 20 inches will not clear the rotor, and spoke clearance must still be checked against the AMG 6-piston caliper.
- The kit uses a Genuine OEM AMG 6-Piston Caliper in front and a Genuine OEM AMG EPB Single-Piston Caliper with 380mm carbon-ceramic rear rotors to retain the W221/V221 electronic parking-brake architecture.
- Brackets, rotor-hat offsets, and caliper mounting are matched to the buyer’s exact S350, S400, S500, S550, S600, S63, or S65 trim rather than treated as one universal W221/V221 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 400 mm front rotor, so the minimum wheel size is 20". Wheels under 20" 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 Genuine OEM AMG 6-Piston Caliper is the primary front upgrade and spreads clamping load across a larger pad area for stronger bite, better pressure distribution, and a firmer pedal under heat. Its OEM AMG provenance matters on this chassis because it is a production-derived performance caliper rather than an unverified universal casting. StopFlex pairs it with the correct 400mm carbon-ceramic rotor, hat offset, mounting hardware, lines, and brackets for the confirmed W221/V221 trim.
Rear Caliper (Balance)
The Genuine OEM AMG EPB Single-Piston Caliper works with the 380mm rear carbon-ceramic rotor to keep rear braking contribution stable without over-driving the rear axle. It is selected to retain the factory electronic parking brake function used on the W221/V221 S-Class.
Front & rear, engineered together: The 400mm front and 380mm rear carbon-ceramic package is engineered as a system so pedal travel, rotor torque, heat capacity, and rear stability are considered together. A front-only conversion on a W221/V221 can leave the rear brakes, EPB integration, and brake-bias behavior mismatched to the new front torque capacity.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact W221/V221 trim?
Fitment is not treated as universal across the S-Class chassis. StopFlex confirms your exact S350, S400, S500, S550, S600, S63, or S65 trim and engineers the brackets, rotor-hat offsets, and caliper mounting for that car before production.
What wheel size do I need for the 400mm front rotor?
The 400mm front rotor requires 20-inch or larger wheels. Wheels under 20 inches will not clear the rotor, and 20-inch wheels still need spoke-clearance confirmation against the Genuine OEM AMG 6-Piston Caliper.
Will the electronic parking brake still work?
Yes, this kit uses a Genuine OEM AMG EPB Single-Piston Caliper at the rear so the W221/V221 electronic parking brake architecture is retained when the kit is configured correctly for the vehicle.
Why choose carbon-ceramic rotors on a W221/V221 S-Class?
Carbon-ceramic rotors reduce brake dust and rotating unsprung weight while adding heat capacity for repeated high-speed braking. On a heavy S-Class, that directly addresses front rotor heat load, wheel cleanliness, and steering feel compared with a conventional iron setup.
