2019-2026+ Mercedes-AMG A45 S / A35 (W177/V177) Carbon Ceramic Brake Kit — OEM-Size Replacement
W177/V177 AMG A45 S and A35 owners usually shop carbon ceramic brakes after repeated hard stops expose the limits of heavy iron rotors: heat fade, pad transfer, brake dust, and front-end mass. This StopFlex OEM-size kit matches the A45 S 360mm front/330mm rear package and the A35 350mm front/330mm rear package, using carbon-ceramic rotors with matched pads, hats, and floating hardware for lower unsprung weight and cleaner high-temperature performance without changing the factory brake layout.
- A45 S fitment is built around the OEM-size 360mm front rotor and 330mm rear rotor package used on the W177/V177 AMG A45 S.
- A35 fitment is built around the OEM-size 350mm front rotor and 330mm rear rotor package used on the W177/V177 AMG A35.
- The kit retains the factory-style caliper locations and rear electronic parking brake function because the rotor sizes, hats, pads, and floating hardware are matched to the listed AMG A-Class brake setup.

For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 360 mm rotor, so the minimum wheel size is 19". Wheels under 19" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
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.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
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.

FAQ
Will this kit fit both the AMG A45 S and AMG A35?
Yes, but only in the exact OEM-size configurations listed on this page: A45 S with 360mm front and 330mm rear rotors, and A35 with 350mm front and 330mm rear rotors. Verify your front rotor diameter before ordering because the A45 S and A35 front brake packages are not the same size.
Will my electronic parking brake and auto-hold still work?
The rear components are designed as OEM-size replacements for the 330mm W177/V177 rear brake package, so the factory rear electronic parking brake function is retained when the car has the listed rear setup. Auto-hold remains a vehicle control function, not a rotor-specific feature.
Why switch from the factory iron rotors on this chassis?
The W177/V177 AMG A45 S and A35 put high brake load through a compact AWD platform, especially in repeated mountain-road or track-session braking. Carbon-ceramic rotors reduce unsprung mass, cut visible brake dust, and handle repeated heat cycles with less fade than comparable iron rotors when paired with the supplied pads.
What should I confirm before ordering?
Confirm your model year, A45 S or A35 trim, W177/V177 chassis, front rotor diameter, 330mm rear rotor package, wheel barrel clearance, and whether your car has any non-factory brake conversion. This page is not for other A-Class trims or unknown rotor-size packages.
