replacement of front retarding discs and boot-trees

necessary equipment

tool:

1. jack
2. balonnyy key to "17"
3. keys "to 13", "to 15" and "to 17"
4. piece of wire (for the fixation of support in the suspended state)
5. brush on metal

order of performance of operations

1. we place under the rear wheels of automobile recoilless supports
2. we weaken the clamp bolts of wheel disks
3. for facilitating the access to the bolts it is possible to turn inside out control to the side, opposite to that, with which we work
4. Poddomkrachivayem automobile, we place it on the supports. ATTENTION! Do not leave machine with performing of work on jack!
5. We remove wheel disks



6. using keys "to 15" and "to 13" we unscrew the bolts of upper and lower guides ("it is finger") support
7. after removing support, we take out from the clamp brake shoes. With the aid of the previously prepared wire we hang up support to the stationary parts of the suspension (for example, to the turns of spring). Try not to stretch and superfluously to not overwind brake hose!
8. Having preliminarily unscrewed the cover of brake tank, with the aid of the mounting or other improvised means we accurately melt down the piston of support to the refusal. For this it is necessary to create uniform pressure on the end of piston. In this case it is desirable so that assistant would retain the support by hands.
9. By key "to 17" we unscrew the upper and lower strap bolts of support. These bolts fairly often bake; therefore it is necessary to be collected forces, patience and accuracy in order not to tear away the face of bolts
10. after removing the clamp of support, we obtain access to the wheel boss. With the aid of the wire brush we thoroughly clean mud from nave, especially - the halt plane of disk.



11. We check the state of the guides of support in the clamp. Let us visually inspect anthers. If there are no holes, then we check mobility it is finger in the clamp. If fingers dvizhutsya too easily, or, which is worse, they do not move generally - we take out finger from the clamp by all accessible means, and we thoroughly clean its surface and cavity inside the clamp. In the cavity we add lubricants of the type grease or if worst comes to worst SHRUS-YA. We slip over fingers entire (if necessary - new) anthers and put fingers in the clamp. We attentively look so that the anthers would correctly lie both ends into the special turnings (on finger and clamp respectively).



12. We assemble in the reverse order. Retarding discs must be degreased, since fatty lubricant for the transport and the corrosion protection is often substituted on them. Special attention should be given to the installation of boot-trees - they must be placed without the misalignments, and their outward flange must coincide with outer circumference of retarding discs.

ATTENTION!

- the first several pressures on the brake pedal can lead to its complete submerging into the floor - this brake piston leaves to operating the position;
- it is necessary to be to ready for the fact that during the first kilometers of path the effectiveness of braking will be considerably lowered;
- to avoid the deformation of retarding discs during 200-300 km of path it follows to avoid intensive braking.
