2024-2026+ Mercedes-Benz E350 / E450 / E53 (W214/S214) CCB Big Brake Kit — Genuine OEM AMG 6-Piston Caliper Front + Genuine OEM AMG 4-Piston Caliper Rear Setup
The W214/S214 E350, E450, and E53 owner shopping this kit is usually solving heat, brake dust, and wheel-clearance uncertainty at the same time. StopFlex builds this package around 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, giving the car higher thermal capacity, lower iron dust, and reduced rotating mass versus an iron big-brake setup. Because E350, E450, and E53 hardware can differ at the knuckle, hub, and wheel package, each kit is engineered to the confirmed trim rather than sold as a platform-wide bolt-on.
- 390mm front carbon-ceramic rotors require 20-inch or larger wheels on the W214/S214 E-Class; wheels under 20 inches will not clear, and spoke clearance must still be checked.
- Front braking is upgraded with the exact Genuine OEM AMG 6-Piston Caliper and a 390mm rotor, while the rear uses a Genuine OEM AMG 4-Piston Caliper with a 380mm rotor.
- E350, E450, and E53 W214/S214 variants are treated as separate fitments because brackets, rotor-hat offsets, caliper mounting, hub geometry, and wheel ET clearance can differ by 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 the Genuine OEM AMG 6-Piston Caliper, giving the 390mm carbon-ceramic rotor a large, stiff clamping package for repeatable pedal response under repeated high-speed stops. Its OEM AMG provenance matters on a W214/S214 upgrade because the caliper architecture is derived from Mercedes-AMG performance hardware rather than a cosmetic universal caliper. StopFlex matches the caliper mounting, bracket geometry, and rotor-hat offset to the buyer’s exact E350, E450, or E53 configuration.
Rear Caliper (Balance)
The rear axle uses the Genuine OEM AMG 4-Piston Caliper with a 380mm carbon-ceramic rotor so rear torque contribution is part of the system rather than an afterthought. On EPB-equipped W214/S214 cars, rear packaging is specified to retain the factory electronic parking brake functions where the confirmed vehicle configuration allows it.
Front & rear, engineered together: The 390mm front and 380mm rear package is engineered as a matched system so brake torque, thermal capacity, and pedal behavior are balanced across both axles. That matters on the W214/S214 because a front-only caliper increase can shift bias forward and leave the rear axle thermally and visually mismatched.
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 E350, E450, or E53?
Fitment is confirmed per vehicle, not assumed from the W214/S214 chassis code. StopFlex verifies the exact model, trim, body style, wheel data, hub geometry, and clearance requirements before machining brackets and rotor hats for your car.
What wheel size do I need for the 390mm front rotor?
The 390mm front rotor requires 20-inch or larger wheels. Wheels below 20 inches will not clear the rotor, and 20-inch wheels still need spoke-clearance confirmation for the Genuine OEM AMG 6-Piston Caliper.
Will the factory electronic parking brake still work?
The W214/S214 E-Class uses an electric parking brake, so EPB compatibility is part of the rear fitment review. StopFlex confirms the rear caliper, parking-brake integration, and electronic function against the buyer’s exact trim before production.
Why choose carbon-ceramic instead of larger iron brakes on this car?
Carbon-ceramic rotors reduce brake dust, resist heat-related fade, and cut rotating mass compared with an equivalent iron big-brake package. On the W214/S214 E-Class, that is useful for heavy road use, repeated high-speed braking, open-wheel cleanliness, and sharper steering response from lower unsprung weight.
