Audi Q5 Adjust Drum Brakes at your home or office.

How important is this service?

Older cars rely on drum brakes for the rear wheels. Drum brakes are a large, metal cylindrical housing on each wheel that are necessary to help your vehicle slow down or stop. Attached to the drum brakes are the brake shoes. When you deploy the brake pedal, brake fluid runs to the brake shoes, and helps them apply pressure to the brake drums. The friction between the drums and the shoes slows down your vehicle. This constant friction makes the drum brakes thinner over time, as the surface layer of the drum keeps wearing off. As the drums become thinner, the space between them and the shoes grows. This distance means that the shoes do not come into as strong of contact with the drums as they normally do, and the braking system will be less efficient than normal.
