2013-2018 Mercedes-Benz A180 / A200 / A250 / A45 (W176) CCB Big Brake Kit — Genuine OEM AMG 4-Piston Caliper Front + Genuine OEM AMG EPB Single-Piston Caliper Rear Setup
The W176 A180, A200, A250 and A45 share the A-Class chassis name, but the brake conversion cannot be treated as one platform-wide bolt-on because AMG and non-AMG trims can differ at the knuckle, hub and wheel-clearance level. This StopFlex kit is engineered around a 350mm front carbon-ceramic rotor with a Genuine OEM AMG 4-Piston Caliper and a 330mm rear carbon-ceramic rotor with a Genuine OEM AMG EPB Single-Piston Caliper, giving the car more heat capacity, lower brake dust and reduced rotating mass compared with an iron upgrade. Each order is built to the confirmed trim so the brackets, rotor hats, offsets, hardware and lines match the exact car rather than an assumed W176 layout.
- 350mm front carbon-ceramic rotors require 18 inch or larger wheels; wheels under 18 inches will not clear the rotor, and spoke clearance must still be checked against the Genuine OEM AMG 4-Piston Caliper.
- Rear braking is matched with a 330mm carbon-ceramic rotor and Genuine OEM AMG EPB Single-Piston Caliper so W176 cars equipped with the electronic parking brake retain EPB function.
- A180, A200, A250 and A45 W176 trims are verified individually because the A45 AMG performance variant can have different front upright, hub and wheel-offset clearance than standard A-Class models.

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 350 mm front rotor, so the minimum wheel size is 18". Wheels under 18" 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 4-Piston Caliper, giving the 350mm rotor a rigid multi-piston clamp package for more even pad loading and a firmer pedal than a small sliding-caliper setup. Its OEM AMG provenance matters on the W176 because the caliper was designed for production-car durability, serviceability and thermal load rather than being an unknown universal casting. StopFlex matches its mounting position, bracket geometry and rotor-hat offset to the buyer's confirmed A180, A200, A250 or A45 trim.
Rear Caliper (Balance)
The rear axle uses the Genuine OEM AMG EPB Single-Piston Caliper with a 330mm carbon-ceramic rotor to keep rear brake contribution proportional to the 350mm front upgrade. On W176 cars equipped with the electronic parking brake, the rear package is configured to retain EPB operation instead of deleting the parking-brake function.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so the larger 350mm front rotor and 330mm rear rotor work with compatible caliper torque, pad area and hydraulic behavior. Matching both axles avoids the common front-only problem of adding thermal capacity at the nose while leaving rear bias, stability and parking-brake integration unresolved.
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 W176 A180, A200, A250 or A45?
Fitment is built around your confirmed trim, not just the W176 chassis code. StopFlex verifies the front knuckle/upright, hub geometry, rotor-hat offset, caliper bracket, brake-line routing and wheel data before producing the kit, because A45 AMG hardware and standard A-Class hardware may not share the same mounting and clearance requirements.
What wheel size do I need for the 350mm front rotor?
The 350mm front carbon-ceramic rotor requires at least an 18 inch wheel. Diameter alone is not enough; the wheel spoke shape and offset must clear the Genuine OEM AMG 4-Piston Caliper, so wheel specifications or a template check should be confirmed before ordering.
Will the electronic parking brake still work?
Yes, when the vehicle is equipped with factory EPB, the rear package uses the Genuine OEM AMG EPB Single-Piston Caliper with the 330mm rear carbon-ceramic rotor so the parking-brake function is retained. StopFlex confirms the rear caliper and harness compatibility against the exact W176 trim before the kit is built.
Why choose carbon-ceramic rotors instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust, resist heat fade and lower rotating mass compared with an equivalent iron rotor package. On a W176 used for fast road driving, repeated mountain braking or track sessions, that means more stable pedal behavior and less wheel contamination while keeping the 350mm front and 330mm rear brake package sized to the car.
