2020-2026+ Mercedes-AMG GLB35 (X247) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2020-2026+ Mercedes-AMG GLB35 (X247) Carbon Ceramic Brake Kit — OEM-Size Replacement
This OEM-replacement StopFlex kit is built for 2020-2026+ Mercedes-AMG GLB35 X247 owners replacing the factory 350mm front and 330mm rear iron brake package with carbon-ceramic rotors in the same reference sizes. The payoff is lower rotating and unsprung mass, cleaner wheels, and better thermal stability during repeated highway-speed stops or mountain-road use, while retaining the GLB35 brake layout, hats, pads, and floating hardware required for a direct-size conversion.
- Matches the GLB35 X247 rotor references for this page: 350mm front rotors and 330mm rear rotors, not GLB250 or non-AMG brake sizing.
- Built as a complete OEM-size replacement package with carbon-ceramic rotors, matched pads, hats, and floating hardware for the AMG GLB35 brake package.
- Targets the GLB35 owner dealing with iron-rotor dust, heat checking, pedal softness after repeated stops, or the higher rotating weight of the stock steel discs.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG GLB35 (X247) |
| Model years | 2020-2026+ |
| Front rotor reference | GLB35: 350mm |
| Rear rotor reference | GLB35: 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 Mercedes-Benz GLB X247?
No. This page is only for the 2020-2026+ Mercedes-AMG GLB35 X247 with the listed 350mm front and 330mm rear rotor references. It is not a universal GLB X247 kit and should not be ordered for GLB250 brake hardware.
Do I need to change calipers to install this OEM-size replacement kit?
This kit is specified around the GLB35 OEM-size brake package, so the rotor diameters stay at 350mm front and 330mm rear. Confirm your existing calipers, rotor dimensions, and wheel clearance before ordering because fitment is limited to the brake setup listed on this page.
Will the rear electronic parking brake and auto-hold functions still work?
The kit is designed as an OEM-size rear replacement for the GLB35 brake package, so the vehicle-side EPB and brake control functions are retained when installed with the correct rear hardware and pads. Any service-mode procedure should follow Mercedes-Benz workshop practice during rear brake replacement.
Why switch a GLB35 from iron rotors to carbon-ceramic rotors?
Carbon-ceramic rotors reduce brake dust and rotating mass compared with iron rotors and handle repeated heat cycles with less fade. On the GLB35, the benefit is most noticeable on open AMG wheels, repeated fast-road braking, and owners who want the 350mm/330mm brake package to run cleaner and more consistently.
