Repair and car operation

Together with a forward wheel in a stream of air the steel disk rotates. It is covered sedlovidno by a so-called support of the disk brake mechanism. By pressing a brake pedal pistons press brake shoes to disks – there is a braking process.

For achievement of higher forces operating on a brake shoe, the Audi 80 model with the 6-cylinder engine it is equipped with two brake cylinders on a support.

The stream of air running at movement constantly cools the disk brake mechanism. Additional cooling of forward disk brake mechanisms is provided at the models equipped with engines in capacity of 85 kW and more, but also at models with the engine in capacity of 66 kW in a combination to an automatic transmission: on a disk of the brake mechanism there is big dredging which grasp air, thereby improving cooling.

The design of disk brake mechanisms of forward wheels Аudi 80 and (where they are established) back wheels has a so-called floating bracket. The support of the brake mechanism looks as the clenched fist. The brake cylinder with the piston presses an internal block to a brake disk because of what the case of the cylinder moves ahead on directing and presses a brake shoe to a brake disk on other party.

Disk brakes at damp weather

At a constant rain the located openly brake disks plentifully are moistened, and as a result of it brake influence attacks a fraction of a second later. Moisture between brake disks and brake shoes should evaporate at first. In the winter when salt is actively used, this effect is shown even more strongly because got on brake shoes and disks salt when braking at first should be erased from them.
