10.3.2. Replacement of brake shoes

GENERAL INFORMATION

Scheme of functioning of the mechanism of automatic adjustment of a gap of brake shoes of a back brake of Gerling

 

And – normal situation,
In – situation of braking,
1–brake shoe,
2–lever of a gear plate,

3–gap,
4–connector of management,
5–managements,
6–a bearing brake board

Prevention

Brake slips are pasted to brake shoes. The new synchronous block (lobby) has a slip a little more thickly, than an asynchronous block (back). The forward brake slip wears out quicker and both blocks reach boundary wear almost at the same time.


Removal

PERFORMANCE ORDER
1. To weaken nuts of fastening of back wheels.
2. To lift and fix a back part of the car, to remove a back wheel.
3. To remove a brake drum.
4. To remove the conductor of a forward brake shoe (synchronous), pressurizing flat-nose pliers a cup to a spring of the conductor of a block and turning it on 90 ° at simultaneous keeping behind a conductor core, to remove a cup with a spring and to take a core of the conductor of a block.
Berlin of 2,0 dm3 and комби
5. To delay a forward brake shoe from a bearing brake board, at the same time turning the top end of a block outside.
6. To unhook the top and bottom returnable spring from a forward block.
7. To remove a forward brake shoe (synchronous).
Berlin of 1,3 and 1,6 dm3
8. To lift a forward brake shoe from a support in the bottom of, by means of a screw-driver rested against a support, to remove the block end from a support, to move it in the direction of a back block and to unhook the bottom returnable spring.
9. To delay a forward block above from the cylinder and to move it about the cylinder in the direction of a back block not to damage a rubber casing of the cylinder.
10. To unhook the top returnable spring by means of passatizhy, inserted into an opening of a flange of a nave of the wheel, established over the top returnable spring after the corresponding rotation of a flange of a nave.
11. To incline forward up the lower part of a forward brake shoe to a detachment of the lever of adjustment of a gap from a latch.
12. To disconnect a forward brake shoe from a press core.
All types
13. To remove a cup, a spring and the conductor of a back brake shoe (asynchronous), similarly as well as the conductor of a forward block.
14. To remove a back brake shoe with the lever of the hand brake and to unhook a cable of the hand brake.
15. To disconnect the lever of automatic adjustment of a gap together with a spring from a back brake shoe (asynchronous).

Installation

PERFORMANCE ORDER
1. To check and clear details and bearing brake board (it is possible to wash out it alcohol).
2. To put a little special Wolfracote greasing on six elements of a bearing brake board.
3. To connect the lever of automatic adjustment of a gap together with a spring and a cable of the hand brake to a back brake shoe (asynchronous).
4. To insert a back block (asynchronous), opiry its ends into the piston and a support in the lower part of a bearing brake board.
5. To establish the conductor of a back brake shoe (asynchronous).
Berlin of 2,0 dm3 and комби
6. To hook on returnable springs (top and bottom) for a forward brake shoe (synchronous), holding a block perpendicularly to a bearing brake board.
7. To establish the bottom end of a forward brake shoe (synchronous) in a support in the bottom of a bearing brake board, and the top end of this block in a piston groove.
8. To press a forward block to a bearing brake board.
9. To establish the conductor of a forward brake shoe (synchronous).
Berlin of 1,3 and 1,6 dm3
10. To connect the lever of adjustment of a gap to a latch and to fasten the top returnable spring to a forward block (synchronous).
11. To press a latch down and to incline a forward brake shoe up to disconnect the lever of adjustment of a gap.
12. To connect the lever of adjustment of a gap to a press core.
13. To incline a forward brake shoe (synchronous) down and again to connect the lever of adjustment of a gap to a latch.
14. To establish a forward brake shoe (synchronous) near a support in the lower part of a bearing brake board and to insert the bottom returnable spring.
15. To pick up a forward brake shoe (synchronous) a screw-driver and to establish it on a support.
16. To pull forward the top part of a forward block (synchronous) before its fixing by the adjusting lever.
17. To press a forward brake shoe (synchronous) to a bearing brake board and to fix the block end in a piston groove after easing by a latch screw-driver before combination of an opening of the conductor in a block with a conductor opening in a bearing brake board.
18. To establish the conductor of a forward brake shoe (synchronous).
All types
19. To establish the mechanism of automatic adjustment of a gap of blocks so that to remove back brake shoes.
20. To establish a brake drum.
21. To press a brake pedal several times in order that the mechanism of adjustment earned.
22. To establish back wheels and to put the clamps fastenings of wheels.

23. To lower the car and to tighten nuts of fastening of wheels the corresponding moment.
