| 1. Before the beginning of a partition of the main cylinder, get a 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 a 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 fig. Elements of the main cylinder of 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 him 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 an internal surface of the main cylinder. In the presence of deep scratches or other damages, it is necessary to replace the cylinder. Do not try to restore an internal surface of the cylinder. |
| 10. Replace all elements included in a repair set, following instructions which are applied to a set. Wash out all old elements cleaning liquid of brake system. |
Prevention
Do not use solvents on the basis of gasoline. At assembly grease all elements with pure brake liquid.
|
| 11. Establish 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. Establish tank plugs, a tank and the fixing screw. |
| 14. Before installation of the main cylinder it is necessary for pumping over on a desktop. As you should apply pressure to the piston of the main cylinder and, during the same time, to supervise an exit of brake liquid from cylinder channels, it is necessary to establish the main cylinder 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 liquid of recommended type (see subsection 2.1). |
| 17. Turn off one of caps and press the piston into the cylinder in order that air left the cylinder. To press the piston deep into the cylinder it is possible to use a big crosswise screw-driver. |
| 18. In order that air again did not get to the main cylinder, it is necessary to twirl a cap before releasing the piston. |
| 19. Repeat this operation until from an opening of the cylinder there will be no pure brake liquid without air vials. Then perform the same operation on connection of the second brake tube. Watch level of brake liquid in a tank in order that air again did not get to the main cylinder. |
| 20. As at preliminary pumping of the main cylinder on a desktop there is no need to apply 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, simply densely close an opening a finger in order that air did not get back to the cylinder. Wait some seconds while brake liquid from a tank will get to the main cylinder, and then press on the piston again, having cleaned a finger at an exit of brake liquid. Do not forget to close again a finger an opening before releasing the piston. On termination of pumping on connection of one brake tube, pass to other opening. |
