Dynamic Friction Company Disc Brake Rotor P/N:604-63185
Dynamic Friction 900-63185 front brake rotor for the 2021-2026 Mercedes-Benz GLA250 and other vehicles gives the brake pads a surface to clamp. The Dynamic Friction brake rotor is a vented, non-directional disc.
A pulsing brake pedal, vibration under braking or grooves across the rotor face can mean the rotor is worn. Before you replace it, rule out worn pads or a sticking caliper, which can feel much the same. This listing is one rotor; the other front side is a separate order, and the two are normally replaced together.
As a front brake rotor, it fits the 2021-2026 Mercedes-Benz GLA250, the 2020-2026 Mercedes-Benz GLB250 and the 2023-2025 Mercedes-Benz EQB 250+, and each takes two. Owners of other Mercedes-Benz models can look up their year in the "Vehicles it fits" section.
