Your Audi A4 brake pads are essential to the braking performance of your vehicle, producing the friction that is needed to bring the vehicle to a stop. Lined with a friction compound made up of carbon, metal filings and strong adhesives, the A4 brake pads grip the contact surfaces on each side of the brake disc securely to work against the momentum of the wheel rotation, bringing its motion to a stop. The Audi A4 brake pads are pressed into contact with the brake disc by the brake caliper when the brakes are applied, pushed inwards by the caliper piston, which uses pressure exerted by hydraulic fluid pressure to operate.

Each time the brakes are applied, the A4 brake pads lose a bit of their friction lining, worn away gradually every time they contact the brake disc. This gradual thinning of the friction compound makes it necessary to replace the Audi A4 brake pads at regular intervals to preserve the efficiency of the brake system.

If this simple maintenance procedure is not done in a timely fashion, the lining of the A4 brake pads can become dangerously thin, failing to grip the brake disc securely to stop your vehicle. Worn Audi A4 brake pads can be damaging to the brake disc, gouging their surface to create deep grooves, making their replacement necessary, a hassle that is easily avoided with good maintenance.
