Replacement of brake liquidIt will be necessary for carrying out work for you:
- A cap key for the union of removal of air. For example, HAZET 1968-7.
- A transparent plastic hose in internal diameter of 6 mm and capacity for collecting brake liquid.
- About 1.0 l of brake liquid.
Brake liquid through a time of brake hoses, and also ventilating openings of the tank of liquid absorbs moisture. Thereof in use there is a decrease in temperature of boiling of brake liquid. At considerable load of brakes it can lead to formation of vials of steam in brake pipelines that reduces efficiency of action of brakes. Therefore it is necessary to replace brake liquid each 2 years.
1 Observe rules of the treatment of the brake liquid, stated in the Section Brake liquid - the main data and security measures.
On HUNDRED air from hydrosystem of brakes, as a rule, is removed by means of the special device. The device submits brake liquid to the tank under the pressure of 2.0 bar. It is possible to carry out this operation and without use of the special tool. In this case air from brake system is removed kachatelny movements of a pedal of a brake. Operation is carried out by means of the assistant.
2 Note liquid level on the tank. After replacement of liquid restore former level of liquid. Thus, the tank modulation is excluded by liquid at replacement of brake shoes.
3 Suck away liquid from the tank to level of 10 mm.
Sequence of removal of air
1. Support the back right.
2. Support the back left.
3. Support the forward right.
4. Support the forward left.
5 Put on the union of the right back brake cylinder a pure hose and substitute the corresponding capacity.
6 Ask the assistant to press a pedal of a brake so that to feel resistance slowly.
8 Repeat the described procedure so many time, how many it is necessary in order that leaving liquid did not contain bubbles. Fresh liquid is learned on light color.
9 Slightly tighten the union. The moment of an inhaling depends on diameter of a carving: the union in diameter of 7 mm is tightened by the moment of 5 N • m, diameter of 11 mm the moment of 15 N • m.
10 Similarly, in the order specified above, pump out brake liquid from other supports.
11 After replacement of brake liquid press a pedal of a brake and check its free wheeling. It should not exceed 1/3 general courses of a pedal.
12 Cars with RKPP: As the drive of coupling works at brake liquid, liquid replacement in hydrosystem of coupling is made in the way described above.
13 Before replacement of brake liquid fill it in the tank to noted level.
14 Screw a cover on the tank.
15 in summary brake several times on the road with a rare traffic. Thus at least once execute complete braking at which works ABS, in particular, on soil. Work of ABS is felt on pulsations of a pedal of a brake.
