Product Overview

The front brake disc, OEM number A1764210212, is fitted to the Mercedes-AMG performance variants across the compact platform, covering the A-Class A45 AMG (W176), CLA45 AMG (C117), and GLA45 AMG (X156). Since this disc is specific to the higher-performance AMG 45 models rather than the standard trims, it's a part worth stocking separately for distributors serving performance-focused workshops and enthusiast markets.

Worn units typically show up as a pulsating brake pedal, squealing or grinding noise while braking, or visible scoring, grooves, or heat discoloration on the disc surface. GSK Auto manufactures this brake disc to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this disc is specific to AMG 45 performance variants and differs from the brake disc used on standard A-Class, CLA, and GLA trims, so it's worth checking which model your customer has before ordering.)

What Is a Brake Disc?

Function: The brake disc, also called a rotor, is the rotating component that the brake caliper clamps against using the brake pads, creating the friction that slows and stops the vehicle.

Working Principle: When the brake pedal is pressed, hydraulic pressure forces the brake pads against the spinning disc, converting the vehicle's kinetic energy into heat through friction, which the disc's design helps dissipate.

Importance: On a performance-oriented AMG model, the brake disc has to handle significantly higher heat loads and braking forces than a standard trim, so using the correct AMG-specific disc matters for both stopping performance and disc longevity.

Common Failures & Signs: Warping causing a pulsating or vibrating brake pedal. Squealing or grinding noise while braking. Visible scoring, grooves, or cracks on the disc surface. Heat discoloration (bluing) indicating excessive thermal stress.
