Details of the main cylinder of brakes with a big tank

The main cylinder of brakes is mounted in a motor compartment on the vacuum amplifier.


1. With Sprintsovka remove from a tank a part of liquid.
2. Substitute under the cylinder the pallet or spread rags.
3. Release the union of tubes on the main cylinder.
4. Disconnect and muffle tubes.
5. Disconnect from a tank the socket (if it is provided), unscrew 2 nuts of fastening of the cylinder to the vacuum amplifier and remove the cylinder.


On cars cylinders with a big or small tank are established, procedures of dismantling assembly of these units almost differ nothing, except for reservations.

Before dismantling get ремкомплект the cylinder.

1. On the cylinder with a small tank unscrew a bolt of fastening of a tank.
2. Weaken collars of a tank (And) and the union (In) and remove a tank.
3. On the cylinder with a big tank unscrew the screw and remove a tank.
4. Check a laying condition.
5. Clamp the cylinder in a vice, wring out pistons and unscrew a lock bolt. Laying of a bolt replace.
6. Again wring out pistons and remove a lock ring.
7. Disassemble the cylinder, having paid attention to an order of installation of details.
8. Get the primary piston.
9. Having knocked about whetstone, get the secondary piston, without allowing a distortion, the cylinder otherwise will be scratched.
10. Special attention turn on springs which for different pistons differ.
11. Check a cylinder condition.
12. At detection of scratches or the painted sites replace the cylinder. Хоннинговать the cylinder is forbidden.
13. Replace all details, having established new of ремкомплекта in a former order. Before assembly dip details into brake liquid.
14. Collect pistons, enter into the cylinder, wring out and wrap a lock bolt.
15. Establish a lock new ring, having tracked that the ring entered into a flute.
16. Establish laying of a tank and a tank.
17. At installation fill the cylinder with liquid.
18. Clamp the cylinder in a vice for a flange, fill in in a tank liquid, wrap caps and press the piston a big krestovy screw-driver.
19. Unscrew a cap that there was an air.
20. Wrap a cap and release the piston.
21. Repeat these actions until the opening under the union will not start to leave liquid. All the time support liquid level in a tank.
22. Repeat actions on air removal for other opening.
23. Instead of a cap it is possible to close an opening a finger.
24. Release a finger after pressing pistons, after an effluence of liquid close an opening a finger and release pistons.
25. Some seconds later again press the piston and clean a finger.
26. Repeat procedure and execute the same actions on other opening.
27. After liquid will start to follow from openings only, wrap caps.


1. Establish the cylinder on a place and wrap nuts by hand.
2. Screw the union without distortions, manipulating the cylinder.
3. Tighten a nut and the union.
4. Add liquid in a tank before the top division and wrap a stopper.
5. It is possible to remove air from the cylinder and on the car, working together. For this purpose ask the assistant to press a pedal and to hold.
6. Unscrew the union and let the air out.
