| 1. Before a partition of the main cylinder, acquire repair set which will contain all necessary spare parts, and also instructions which can be specific to your model. |
|
|
2. Turn off the fixing screw of a tank, remove a tank. |
|
3. After removal of a tank remove plugs from openings of the main cylinder; if they hardened, burst, are damaged or proceed, replace them. |
|
|
4. Clamp the cylinder in a vice and with the help a small beard or the crosswise screw-driver lower pistons on the bottom of the cylinder. Holding pistons in this situation, remove a lock bolt of the main cylinder. |
|
5. Accurately remove a cutting lock ring on the end of the main cylinder. |
| 6. Now it is possible to get internal elements of the cylinder (see rice. Elements of the main cylinder of the brake system). At removal remember an order of installation of elements in order that at their assembly it was possible to establish correctly. |
|
7. After removal of a cutting lock ring it is possible to remove the first piston (N1). |
|
8. Get the cylinder from a vice and knock with it on a wooden surface so that the second piston (N2) seemed. Pull out the piston absolutely directly, – if its stories aside, the internal proverkhnost of the cylinder can be damaged. |
Prevention
Two springs of the cylinder differ among themselves therefore pay special attention to the provision of their installation.
|
| 9. Carefully examine the internal surface of the main cylinder. In the presence of deep scratches or other damages, the cylinder needs to be replaced. Do not try to restore the internal surface of the cylinder. |
| 10. Replace all elements included in repair set, following instructions which are attached to set. Wash out all old elements the cleaning liquid of the brake system. |
Prevention
Do not use solvents on the basis of gasoline. At assembly grease all elements with pure brake fluid.
|
| 11. Install collected elements in the cylinder and press them deep into the cylinder. Then, establish a lock bolt. |
| 12. Establish a new cutting lock ring, having checked that it densely sat in the flute. |
| 13. Install tank plugs, a tank and the fixing screw. |
| 14. Before installation of the main cylinder it needs to be pumped over on a desktop. As you should apply pressure to the piston of the main cylinder and, in the same time, to control an exit of brake fluid from channels of the cylinder, the main cylinder needs to be installed in a vice so that sponges of a vice clamped a fixing flange of the cylinder. |
| 15. Twirl caps in the openings intended for brake tubes on the main cylinder so that they did not pass air, but it is not too strong that they could be turned off easily. |
| 16. Fill a tank with brake fluid of the recommended type (see subsection 2.1). |
| 17. Turn off one of caps and press the piston into the cylinder in order that air went out of the cylinder. To press the piston deep into of the cylinder it is possible to use the big crosswise screw-driver. |
| 18. In order that air did not get to the main cylinder again, it is necessary to twirl a cap before releasing the piston. |
| 19. Repeat this operation until from an opening of the cylinder there is no pure brake fluid without vials of air. Then perform the same operation on connection of the second brake tube. You watch the level of brake fluid in a tank in order that air did not get to the main cylinder again. |
| 20. As at preliminary pumping of the main cylinder on a desktop there is no need to apply the big pressure upon the piston, there is other way to pump over the cylinder, without turning off and twisting a cap with each piston stroke. Before pressing on the piston, turn off a cap as it is described in item 17. Before releasing the piston instead of twisting a cap, just densely close an opening a finger in order that air did not get back to the cylinder. Wait several seconds until brake fluid from a tank gets to the main cylinder, and then press on the piston again, having taken away a finger at an exit of brake fluid. Do not forget to close a finger an opening again before releasing the piston. Upon completion of pumping on connection of one brake tube, you pass to other opening. |
