The main brake cylinder




Before removal of the main brake cylinder some times press a brake pedal to dump vacuum in the vacuum amplifier.
At removal of the main cylinder it is necessary to take into consideration the distinctions which are available in a design of models of brake system. The description concerning brake mechanisms with ABS is resulted separately.

On following illustrations the kind of the main brake cylinder for both executions (without ABS) is shown.

Kind of the main brake cylinder of the car to the middle of 1995 of release.
1 - brake pipelines
2 - fastening nuts
3 - a tank
4 - the contact switch

Kind of the main brake cylinder of the car from the middle of 1995 of release
1 - штекерное connection
2 - brake pipelines
3 - a tee
4 - the main brake cylinder

1. Disconnect a cable of weight from the storage battery.
2. Расстыкуйте штекерное connection (4) gauges of emergency level of a brake liquid in a place shown on an illustration.
3. Suck away a liquid from a tank on the main cylinder. For this purpose it is possible to take advantage of a pear. For this purpose it is possible to open also the union of removal of air from system and merge a liquid.
4. Substitute under a tank capacity and disconnect from the cylinder the pipeline (1). Remember a place of its joining.
5. Turn on two nuts of fastening and remove the main cylinder from the vacuum amplifier. Watch that the brake liquid has not got on paint and varnish coverings.
6. At the cylinder of new model disconnect the holder of a tee.
7. At the same cylinder remove consolidations and a remote element.
8. If the cylinder is replaced, it is necessary to remove a tank. It sits on two rubber plugs and can be cautiously separated a screw-driver, as shown.


The main cylinder in sequence, by return to removal is established.

1. Nuts of fastening of the cylinder tighten the moment of 13 Nanometers, joining of the pipeline by the moment of 12 Nanometers. Joining of pipelines at a tee is tightened by the moment of 16 Nanometers.
2. In summary remove air from brake system as it is described in section 6.
3. If the tank acted in film, establish it on the main cylinder through rubber plugs, having greased with their brake liquid.


As it was already mentioned, the main cylinder of the car from the middle of 1995 of release is not subject to repair.
Cylinders of earlier release can be disassembled, repaired and collected, but it is recommended to do it in a repair truck.
