Repair and car operation

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

For achievement of higher forces operating on brake колодку, model Audi 80 with the 6-cylinder engine is equipped by 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 by capacity of 85 kw and more, but also at models with the engine capacity of 66 kw in a combination to an automatic transmission: on a disk of the brake mechanism there are big dredging which grasp air, thereby improving cooling.

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

Disk brakes at damp weather

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