Support details
1 – protective cap;
2 – piston;
3 – support;
4 – valve of production of air;
5 – protective cap of the valve;
6 – the directing finger;
7 – protective cap;
8 – plug;
9 – support cylinder;
10 – sealing ring

Removal of the piston from the support cylinder

1 – support;

2 – piston;

3 – wooden laying;

4 – opening of a supply of brake fluid

Removal of a sealing ring

1 – shovel;

2 – sealing ring;

3 – support cylinder

Installation of a protective cap on the piston

1 – protective cap;

2 – piston

Installation of the piston in the support cylinder

1 – piston;

2 – protective cap;

3 – support cylinder

1. Remove a wheel, previously having weakened bolts of its fastening on the car standing on the earth.
2. Turn off a hollow bolt of fastening of a tip 7 (see rice. The forward brake FS III mechanism) a brake hose to a support. Having disconnected a brake hose, muffle its opening.
3. Remove protective caps of 5 guides of fingers.
4. Turn out both directing a finger 4.
5. Remove a support 3 from a rotary fist 8.
6. Take out 3 brake shoes 1 and 2 from a support. If blocks do not be replaced, mark them then to establish on former places. In use blocks are earned extra therefore if to trade their places, braking will be uneven.
7. Accurately, not to damage, take out an edge of a protective cover 1 (see rice. Support details) from a cylinder 9 groove.
8. Clamp a support 1 (see rice. Removal of the piston from the support cylinder) in a vice with slips from soft metal on sponges. Enclose wooden laying 3 not to damage the piston 2 at its extraction from the cylinder.
9. Having given compressed air to the cylinder of a support 1 through an opening 4 supplies of brake fluid, squeeze out the piston 2. Remove wooden laying 3 and finally take out the piston 2 of the cylinder.
10. Take off a protective cap 1 (see rice. Support details) from the piston 2. Replace the cap 1 torn, cracked or lost elasticity.
11. By means of a wooden or plastic shovel 1 (see rice. Removal of a sealing ring) not to damage a cylinder 3 mirror, take out a sealing ring 2 of a cylinder pro-point.
12. Examine a cylinder 9 mirror (see rice. Support details) and piston 2. In the presence of deep risok, scratches, roughnesses, etc. replace a support assembled.
13. Carefully wash out alcohol and dry a stream of compressed air the piston 2 and the cylinder 9.
14. Replace plugs 8 with the rubber torn or lost elasticity.
15. Grease the piston 2 and a new sealing ring with the 10th G 052 150 A2 lubricant or brake fluid.
16. Establish a sealing ring 10 in a cylinder 9 pro-point.
17. Turn inside out a protective cap 1 (see rice. Installation of a protective cap the piston) also put on it a back part of the piston 2.
18. Insert the piston 1 (see rice. Installation of the piston) in the cylinder 3 also install an external edge of a protective cap 2 in the support cylinder, having turned out it back, in a cylinder 3 groove.
19. Press the piston 2 (see rice. Cave-in of the piston in the cylinder) in the cylinder 1 by means of special adaptation 3, at the same time the internal edge of a protective cap has to enter a cylinder groove. In the absence of adaptation it can be made, for example, the wooden handle of the hammer. Press on the piston evenly in different points on all circle, watching that the piston did not warp.
20. Establish a support upside-down. At connection of a brake hose pay attention – under a tip 7 (see rice. The forward brake FS III mechanism) a hose the sealing ring has to be established.
21. Pump over the brake system (see subsection 9.9.6).
