2017-2023 Mercedes-Benz E300 / E350 / E400 / E450 / E43 / E53 / E63 / E63 S (W213/S213/C238/A238) CCB Big Brake Kit — Genuine OEM AMG 6-Piston Caliper Front + Genuine OEM AMG 4-Piston Caliper Rear Setup
Owners of the W213/S213/C238/A238 E-Class shop carbon-ceramic brakes when the factory iron setup is creating heat fade, steering-wheel shake from overheated rotors, heavy dust on open AMG-style wheels, or when replacing high-cost OEM carbon components. This StopFlex kit pairs a 390mm front carbon-ceramic rotor with a Genuine OEM AMG 6-Piston Caliper and a 380mm rear carbon-ceramic rotor with a Genuine OEM AMG 4-Piston Caliper for higher heat capacity, lower rotating mass, and cleaner street use. Each kit is built to the buyer’s confirmed E300, E350, E400, E450, E43, E53, E63, or E63 S configuration, because knuckle geometry, hat offset, and wheel clearance can differ across this E-Class family.
- 390mm front and 380mm rear carbon-ceramic rotors require 20-inch or larger wheels; barrel and spoke clearance are checked before production.
- The front axle uses the exact Genuine OEM AMG 6-Piston Caliper specified for this kit, not a generic aftermarket caliper substituted across multiple Mercedes platforms.
- Standard E-Class and AMG E-Class trims in the W213/S213/C238/A238 family can differ in upright, hub, and wheel-offset clearance, so StopFlex engineers brackets and rotor hats for the confirmed 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 390 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 front axle uses a Genuine OEM AMG 6-Piston Caliper, giving the 390mm carbon-ceramic rotor a broad, rigid clamping interface for consistent pedal response under repeated high-energy stops. Its OEM AMG provenance is important on this chassis because the caliper architecture was developed for Mercedes performance packaging rather than adapted from a universal big-brake catalog. The caliper is matched with StopFlex brackets, hats, pads, lines, and hardware for the customer’s exact E-Class trim.
Rear Caliper (Balance)
The rear axle uses a Genuine OEM AMG 4-Piston Caliper with a 380mm carbon-ceramic rotor to keep rear torque contribution proportional to the larger front package. On EPB-equipped W213/S213/C238/A238 cars, the rear solution is specified to preserve factory electronic parking-brake operation where applicable.
Front & rear, engineered together: The 390mm front and 380mm rear package is engineered as a system so front bite, rear stability, ABS behavior, and pedal travel stay compatible. A matched four-corner kit avoids the bias shift that can happen when a large front-only conversion is installed without the correct rear torque and hydraulic relationship.
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 E300, E450, E53, or E63 S?
Fitment is not treated as a platform-wide W213 bolt-on. StopFlex confirms your year, trim, body style, VIN details, existing brakes, hub geometry, and wheels before building the brackets, rotor hats, and caliper mounting for your specific car.
What wheel size do I need for the 390mm front rotor?
The 390mm front rotor requires 20-inch or larger wheels. Wheel diameter alone is not enough; spoke shape, barrel profile, wheel offset, and spacer use must also be checked against the Genuine OEM AMG 6-Piston Caliper.
Will the electronic parking brake still work?
Yes, the W213/S213/C238/A238 E-Class uses a factory electronic parking brake, and the rear portion of this kit is specified to retain EPB function where the vehicle is equipped with it. Rear service mode procedures still apply during pad or caliper work.
Why convert this E-Class to carbon-ceramic instead of staying with iron rotors?
Carbon-ceramic rotors reduce brake dust, lower rotating and unsprung mass, and handle repeated heat cycles better than an iron street setup of similar size. For cars already fitted with OEM carbon-ceramics, this kit also gives a complete caliper, rotor, pad, hat, hardware, and line package instead of replacing cracked or worn components one part at a time.
