How to properly clean and reassemble a rear brake caliper on Audi 80?

Start with wiping off the outer part of the calliper to keep out of the hole in the hose leading to hydraulic parts no foreign substance. Hold the calliper in a vice with the piston upwards and take off the piston dust cap in its groove. In the case of the Teves calliper a piece of wood in the jaws opposite the piston is inserted, and air pressure is used to push the piston out of the bore through the hydraulic fluid inlet. In the case of Girling calliper, the piston is screwed to the bore, and the screw is removed with an Allen key. Take the piston carefully off the bore, taking care not to scratch the surface, and remove the dust cap of the piston. Unscrew bleed screw and rinse with methylated spirit and dry all parts. Check the piston and bore to presence or absence of corrosion and scoring, check the automatic adjuster threads to determine their wear and inspect the calliper housing to confirm the absence of fluid leakage around the handbrake operating arm. Evaluate guide pins, seals, bushes, etc. in wear and replace parts when needed. In case the calliper and piston are in good conditions, take a repair kit of seals. To start reassembling, pour a small amount of brake fluid on the bore and piston surface, and put the piston seal into the bore groove. In the case of the Teves calliper, insert the clamping component in the calliper against the stop and make sure the threaded insert turns freely, then place the dust cap on the piston and connect it with the calliper but make sure that it fits centrally. The piston should be pressed in the bore with the help of a G-clamp and the dust cap should be clamped into position. In the case of Girling calliper, open the dust cap on the piston, drop it into the groove and screw the piston into the bore pressing hard. Install a new rubber seal on the bleed screw, grease the threads with the brake fluid, and screw it on. Girling callipers are also available in pre-filled new Girling callipers, with brake fluid and it is advisable to fill and bleed Girling and Teves callipers after overhaul. This can be done by ensuring the calliper has been mounted in a vice so that the hydraulic is exposed at the top, loosen the bleed screw, empire this to a brake fluid supply, fill until fluid is released without bubbles, tighten the bleed screw and seal the fluid inlet where required.

Audi Brake Caliper

It's needless to say, the Audi brake caliper is one of the most important part of the disc brake system. In some cars, it is found in the front, while in others, it is at the rear. The brake fluid flows into the caliper when you drive your car and depress the brake pedal. Consequently, this fluid causes pressure against the piston inside, which makes contact with the rotor to stop your vehicle. Nevertheless, with time and heat effects, brake calipers start becoming rusty, thereby leaking brake fluid from them. If you see any leaking of brake fluid here, then you know your braking system needs an overhaul because there might be a problem somewhere surrounding its functioning.

It is better to choose OEM parts when it comes to the time for fixing them. Why? Because they fit perfectly well and ensure safety. For people who prefer doing their maintenance, the genuine Audi Brake Caliper is quite perfect. At AudiPartsGiant.com, we specialize in genuine Audi Brake Calipers only.
