|1. Mark a paint position of back wheels concerning a nave. It will allow to establish at assemblage отбалансированное a wheel in its former position. Loosen the bolts of fastening of a wheel on the car standing on the earth. Lift the car, put it on supports and remove back wheels.|
|2. Release a cable of a lay brake. Remove sideways a clip – 1. Press the lever at a support in a direction of an arrow and disconnect a brake cable – 3.|
|3. Disconnect a support above and below. Thus keep directing finger a wrench. Remove the case, the brake hose remains attached.|
|4. Remove a support and adhere its wire to a body. The brake hose should not be tense.|
|5. Take out from directing brake Pads and clamps.|
Do not press a brake pedal at removed колодках. Otherwise the piston will be squeezed out from the case. In this case remove a support in the complete set and insert it into place in conditions HUNDRED.
|6. Clear directing surfaces and landing places колодок in mine a rag and spirit. Do not apply for this purpose the solvents containing mineral oils or the tool with sharp edges. |
To brake clearing apply exclusively spirit.
|7. Before installation колодок check up a brake disk, having felt its fingers. At presence задиров brake disks are subject to replacement.|
|8. Measure a thickness of the disk, if necessary worn out disks replace, thus address to subsection Check of a thickness of a brake disk.|
|9. Check up presence of cracks on dusterе the piston. In the presence of damages duster at once replace, as проникшая the dirt quickly leads to loss of tightness of a support. The support for this purpose should understand (work HUNDRED).|
|10. Screw the piston, rotating it in the right party (clockwise) a special key AUDI - 3272, putting for this purpose considerable effort. The fillet (an arrow at the left) the tool should adjoin to a support. At a heavy piston stroke rotate a wrench of 13 mm for лыски () the tool. |
The brake piston cannot be rotated by means of the adaptation for return of the piston or the hammer handle, otherwise it is possible to damage the mechanism of installation of a lay brake.
It is possible to apply also tool HAZET 4970/3.
|11. If the special tool available is not present, make a corresponding steel plate and insert it into both grooves of the piston of a brake. Strong movement rotate the piston. |
At piston rotation the brake liquid from the brake cylinder in the tank is squeezed out. Watch liquid level in the tank, if necessary remove surpluses.
For отсасывания a brake liquid apply a plastic bottle which intends only for this purpose. Do not apply for this purpose a bottle for a drinking liquid! The brake liquid is poisonous. In no event it is impossible to suck away it a mouth through a hose. Apply to this purpose a siphon. After replacement brake колодок liquid level in a tank should not exceed mark MAX in a tank, since. At heating the brake liquid extends. The following liquid flows down on the brake cylinder, destroying a covering and leading to corrosion.
|12. Insert in directing a new clamp.|
|13. Insert in directing brake Pads. With new brake колодок remove a protective film on a return plate.|
|14. Establish a support and tighten the moment 30 Н•м new bolts of fastening. |
In the repair complete set there are four self-stopped a bolt which are necessary for establishing necessarily.
|15. Press the lever – 2 at a support in a direction of an arrow and connect a cable – 3 lay brakes. Insert a clip – 1 sideways at a support.|
|16. Adjust a lay brake, thus address to subsection Adjustment of a lay brake. |
The brake pedal can be pressed only after adjustment of a lay brake.
|17. Establish back wheels so that the marks put at removal, have coincided. Wrap bolts of fastening of a wheel. Lower the car on wheels and wrap bolts of fastening of wheels a cross - crosswise the moment 120 Н•м. |
Some times strongly press a brake pedal so that distinct resistance of a pedal was felt. Thus, Pads will lie down to a brake disk and will take the place.
|18. Check up level of a brake liquid in the tank. If necessary add to mark MAX. |
– Whether fastenings of brake hoses are reliably tightened?
– Whether the brake hose in the holder is fixed?
– Whether unions of removal of air are tightened?
– Whether it is enough in the tank of a brake liquid?
– At the working engine check up tightness of system. For this purpose press a pedal of a brake effort 200 – 300 Н (20 – 30 kg) during 10 with. The pedal should not depart. Check up on tightness all connections
|19. Cautiously allow to be earned extra new brake колодкам. For this purpose some times brake the car since speed 80 to 40 km/hour slightly pressing a pedal. Between braking allow to be cooled to a brake. |
In a number of regions brake Pads should be utilised as a special material. Local authorities should inform drivers on places of the resolved recycling.
