2014-2021 Mercedes-Benz S400 / S450 / S500 / S550 / S560 / S600 / S63 / S65 (W222/V222/C217/A217) CCB Big Brake Kit — Genuine Akebono OEM Porsche 10-Piston (10N) Caliper Front + Genuine Brembo OEM Porsche 19Z 4-Piston Caliper Rear Setup
The W222/V222/C217/A217 S-Class is heavy, fast, and often driven on large open-spoke wheels where iron brake dust, heat cycling, and rotor mass are hard to ignore. This StopFlex kit replaces the factory brake package with 420mm front carbon-ceramic rotors clamped by Genuine Akebono OEM Porsche 10-Piston (10N) Caliper assemblies and 410mm rear carbon-ceramic rotors with Genuine Brembo OEM Porsche 19Z 4-Piston Caliper assemblies. Each kit is engineered to the exact S400, S450, S500, S550, S560, S600, S63, or S65 configuration ordered, including brackets, hat offsets, line routing, and caliper position.
- 420mm front and 410mm rear carbon-ceramic rotors give this S-Class kit the thermal capacity needed for a heavy W222/V222/C217/A217 chassis without stepping down to a cosmetic-only brake package.
- The front axle uses the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, while the rear axle uses the Genuine Brembo OEM Porsche 19Z 4-Piston Caliper to keep rear braking authority in the system.
- Minimum wheel size is 21 inches because the 420mm front rotor will not clear smaller wheels; spoke profile, barrel shape, offset, and spacer use must still be checked before ordering.

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 420 mm front rotor, so the minimum wheel size is 21". Wheels under 21" 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 axle is built around the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, giving this S-Class a large multi-piston clamp area for consistent pad loading across the 420mm carbon-ceramic rotor. Its OEM Porsche provenance matters because the caliper was designed for high-output vehicle braking loads, not as a generic show caliper. StopFlex mounts it with model-specific brackets and rotor-hat geometry matched to the exact W222/V222/C217/A217 trim.
Rear Caliper (Balance)
The rear axle uses a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper on a 410mm carbon-ceramic rotor so the upgrade does not leave the rear axle under-braked relative to the new front torque capacity. For W222/V222/C217/A217 cars with the factory electronic parking brake, the rear package is configured around EPB retention requirements during the fitment confirmation process.
Front & rear, engineered together: The 10-piston front and 4-piston rear package is engineered as a complete system so rotor diameter, pad area, piston layout, and brake torque distribution are matched together. That matters on the S-Class because a front-only increase can change brake balance, ABS behavior, and rear-axle stability under hard deceleration.
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 S400, S550, S63, or S65 trim?
Fitment is confirmed per vehicle, not assumed from the W222/V222/C217/A217 chassis name. StopFlex builds the brackets, rotor-hat offsets, and caliper mounting around your exact model, trim, axle hardware, and wheel package because standard S-Class and AMG variants can differ mechanically.
What wheels are required for the 420mm front rotor?
The 420mm front carbon-ceramic rotor requires at least a 21-inch wheel. Wheel diameter alone is not enough; StopFlex also checks spoke clearance, inner barrel shape, wheel offset, and spacer requirements against the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper.
Will the electronic parking brake still work?
Yes, the W222/V222/C217/A217 S-Class uses an electronic parking brake, and the rear portion of the kit is configured with EPB retention in mind. StopFlex confirms the exact rear setup before production because the 410mm rear rotor and Genuine Brembo OEM Porsche 19Z 4-Piston Caliper must coexist with the vehicle's parking-brake hardware.
Why choose carbon-ceramic over replacement iron brakes on this S-Class?
Carbon-ceramic rotors reduce brake dust, resist heat-related fade, and remove rotating mass compared with a comparable iron rotor package. On a heavy S-Class with large wheels, those gains are most noticeable in repeated high-speed stops, cleaner wheel faces, and sharper response from the front axle.
