A rear brake disc is a key component of the disc braking system, responsible for slowing down and stopping the vehicle through friction between the brake pads and the disc surface. It is mounted to the rear wheel hub and rotates with the wheel.
The disc operates together with the brake caliper, brake pads, ABS system, and in some designs, an integrated parking brake mechanism. Rear discs may be solid, ventilated, or combined with an internal drum for handbrake operation.
Common wear symptoms include vibration during braking, increased stopping distance, uneven pad wear, overheating marks, or visible grooves on the disc surface.
Our catalog includes rear brake discs for many vehicle brands. Genuine brake components, reliable aftermarket replacements, and tested used discs without critical wear are available. Various diameters and thickness options are offered.
Used discs are inspected for minimum thickness, absence of cracks, overheating damage, deep scoring, and structural distortion.
Selection is based on VIN number, disc diameter, brake system type, parking brake configuration, and part number. Timely replacement of rear brake discs ensures safe and stable braking performance.
