Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2013-2018 Mercedes-Benz A-Class / AMG (W176). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2013-2018 | OEM AMG 4-Piston Caliper / 350mm | OEM AMG EPB Single-Piston Caliper / 330mm | 18" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 350 mm rotor sets the minimum wheel size at 18" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front runs the OEM AMG 4-Piston Caliper clamping a 350mm carbon-ceramic rotor. Four opposed pistons give even pad loading and a firm, repeatable pedal on the W176 front axle.
Rear Caliper
The rear uses the OEM AMG EPB Single-Piston Caliper on a 330mm carbon-ceramic rotor, adding rear thermal capacity while keeping the factory electronic parking brake fully functional.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.

FAQ
Will this fit my 18-inch factory wheels?
The 350mm front rotor requires a minimum 18-inch wheel, which covers most W176 setups. Wheel diameter alone isn't the whole story—spoke shape and inner barrel clearance matter over a 350mm disc and the AMG 4-piston caliper. Send us your exact wheel and we'll confirm clearance before you order.
Is this kit built for my specific W176 trim?
Yes. Every kit is engineered for your confirmed trim, not assumed from the W176 platform. An A45 AMG can carry different front knuckles, hub geometry, and wheel offset than an A180, A200, or A250, so brackets, rotor-hat offsets, and caliper mounting are matched to your car. We do not sell this as a universal platform bolt-on.
How do these brakes behave in cold weather?
A cold, untuned carbon-ceramic disc naturally bites less than cold iron—that's physics, not a fault. We've tuned both the pad compound and the disc's ceramic coating for cold starts, so winter first-stop feel on your A-Class comes very close to summer feel. Still, leave a little extra following distance on the first few cold stops of the day.
Does the rear caliper keep my electronic parking brake?
Yes. The rear uses the OEM AMG EPB Single-Piston Caliper on a 330mm rotor, so your factory electronic parking brake works exactly as before. No warning lights, no manual conversion, no loss of the auto-hold function.
