What is the original brand of brake discs for the Audi Q7?

[McPenelope]

Audi Q7's original brake disc brand is TRW Teves. Simply put, a brake disc is a round disc that rotates as the vehicle moves. The brake caliper clamps the brake disc to generate braking force; when you press the brake pedal, it clamps the brake disc to slow down or stop the vehicle. Brake discs offer excellent braking performance and are easier to maintain compared to drum brakes. More details are as follows: 1. Brake discs and pads are used for braking, with the braking force coming from the brake caliper. Typically, standard brake calipers have a fixed inner section where the brake piston pump is located, while the outer section features a clamp-style structure. The inner brake pad is fixed to the piston pump, and the outer brake pad is fixed to the outer part of the caliper. 2. The piston pushes the inner brake pad via the pressure from the brake fluid line, while simultaneously pulling the caliper through reaction force, causing the outer brake pad to move inward. Both pads press against the brake disc, generating braking force through friction between the disc and the inner/outer pads. In this process, the piston is actuated by brake fluid, also known as hydraulic oil.
