2014-2019 Mercedes-AMG GLA45 (X156) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2014-2019 Mercedes-AMG GLA45 (X156) Carbon Ceramic Brake Kit — OEM-Size Replacement
The X156 Mercedes-AMG GLA45 uses large brakes for its compact chassis, and owners who drive hard often shop carbon ceramic to cut heat fade, brake dust, and rotating mass without changing the factory brake balance. This OEM-size StopFlex kit matches the GLA45 350 mm front and 330 mm rear rotor references and includes carbon-ceramic rotors, pads, hats, and floating hardware for the original caliper layout. It is built for buyers who want carbon-ceramic heat stability and cleaner open-wheel appearance while keeping the factory rotor diameters specified for this page.
- Fits the 2014-2019 Mercedes-AMG GLA45 X156 brake package specified on this page with 350 mm front and 330 mm rear rotor references.
- OEM-size carbon-ceramic replacement keeps the GLA45 factory caliper geometry instead of converting the car to a different big-brake rotor diameter.
- Carbon-ceramic rotors reduce brake dust and rotating mass versus iron discs, useful on the GLA45’s short-wheelbase AMG crossover chassis where steering feel and wheel cleanliness are noticeable.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG GLA45 (X156) |
| Model years | 2014-2019 |
| Front rotor reference | GLA45: 350mm |
| Rear rotor reference | GLA45: 330mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 18" (for the 350 mm rotor) |
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 350 mm 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.
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 every 2014-2019 GLA45 X156?
No. This page is limited to Mercedes-AMG GLA45 X156 cars that match the listed 350 mm front and 330 mm rear rotor setup. Confirm your VIN, current rotor diameters, caliper package, and wheel clearance before ordering.
Does the kit keep the factory electronic parking brake and rear brake functions?
The kit is an OEM-size replacement for the listed GLA45 rear rotor reference, so it is intended to work with the factory rear brake layout, including the electronic parking brake system when the car matches this page’s 330 mm rear setup.
Why switch a GLA45 from iron rotors to carbon ceramic rotors?
Carbon ceramic rotors handle repeated high-temperature stops with less fade, make substantially less visible brake dust, and remove rotating mass compared with iron rotors. On a GLA45 used for canyon driving, track days, or aggressive street use, those gains address the common heat, dust, and rotor-wear complaints.
Is this a street kit or a track-only kit?
This is an OEM-size replacement kit for the GLA45, not a race-only conversion. The supplied pads must be matched to the carbon-ceramic discs, and hard track use still requires proper bedding, brake-fluid condition, and post-session inspection.
