Removal and installation of a brake hose

Observe rules of the treatment of the brake liquid, described in the Section Replacement of brake liquid.

Pipelines of brake system carry out communication of the main brake cylinder with four wheel cylinders. Communication between rigid and mobile parts of brake system, for example, between supports is carried out by flexible hoses of a high pressure. In the presence of visible damages the last should be replaced.

Do not allow contact of brake hoses to oil or fuel, do not paint them and do not cover with means for protection of the bottom of the car against corrosion.

The remark on security measures

If one of chambers of the tank of brake liquid is completely emptied (for example, in the presence of a leakage in brake system or if at removal of air forgot to add in the tank liquid), in system air which gets to the pump ABS is sucked in. Air from brake system in this case should be removed on HUNDRED with use of the special device.
