Repair of the hydraulic drive of brakes
|
|
If the pipeline of the brake drive (1) and brake hoses (4) with stamped fixture (3) are connected with elements of a running gear or a body, there should be no springing holder of a hose (2). On an illustration connection is weakened by Rozhkov a wrench of 14 mm and a key for the brake pipeline (above). |
Councils
- Brake fluid is poisonous. Therefore it should not get to a mouth.
- Brake fluid is aggressive in relation to a body covering. Therefore it is impossible to put the rags or tools stained with brake fluid impregnated with brake fluid on body details.
- At removal of a brake hose or the brake pipeline brake fluid gradually follows from a receiver. You can prevent it as follows: before removal of bolted connections weaken the pumping valve in the corresponding contour.
- Put on it a hose and send it to any capacity. Now completely squeeze out a pedal of a brake and record a suitable plate in this situation. Thus drain openings in the main brake cylinder will be closed – brake fluid does not follow any more.
- For removal and installation of the brake pipeline you need to get the key specified illustrations below for the brake pipeline. Also for a priderzhivaniye of brake hoses you will need a rozhkovy wrench of 14 mm.
- After repair of a hydraulic system of brakes it needs to be pumped over. Often happens to pump over enough only that brake contour in which works were carried out.
Removal of the pipeline of the brake drive
|
|
- To turn out the union of the brake pipeline. For this purpose it is necessary to hold an opposite nut of connection – for example, at a brake hose.
- If the nut prirzhavet to a tube because of what it rotates together with a nut, it is necessary to replace this tube. Thin-walled tubes quickly break.
- If the corresponding piece of a tube has to be replaced, for weakening of connections of the pipeline it is possible to use the following reception:
- To saw off the brake pipeline near bolted connection, to turn off a cap nut a six-sided head.
- To insert the brake pipeline in holders.
- To pump over brake system.

Removal of brake hoses
|
|
- At first to unscrew the union of the corresponding brake pipeline. Thus to watch that the pipeline was not overwound.
- If the brake hose is fixed on a body by means of the stamped holder, it is protected by a sheet bracket from slipping. At assembly it is necessary to establish this so-called holder of a hose.
- At installation of a hose it should be twisted at first on that end which has an external carving.
- Then to tighten other carving.
- The brake hose should not be overwound. For control the color strip or a rubber side serves.
- To pump over brake system.
- Right after repair to check, whether the hose rubs somewhere at the springing movements.
- To repeat action after rather long trip.
