Replacement of a brake liquidIt will be necessary for carrying out of work for you:
- Nakidnoj key for the union of removal of air. For example, HAZET 1968-7.
- Transparent plastic hose in internal diameter of 6 mm and capacity for gathering of a brake liquid.
- About 1.0 l of a brake liquid.
The brake liquid through a time of brake hoses, and also ventilating apertures of the tank of a liquid absorbs a moisture. Thereof while in service there is a decrease in temperature of boiling of a brake liquid. At considerable loading on 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 a brake liquid each 2 years.
1 Observe rules of the reference with the brake liquid, stated in Section the Brake liquid - the basic data and security measures.
On HUNDRED air from hydrosystem of brakes, as a rule, leaves by means of the special device. The device submits a brake liquid to the tank under the pressure of 2.0 bar. It is possible to spend this operation and without application of the special tool. In this case air from brake system leaves качательными movements of a pedal of a brake. Operation is carried out by means of the assistant.
2 Note liquid level on the tank. After liquid replacement restore former level of a liquid. Thus, the modulation of the tank is excluded by a liquid at replacement brake Pad.
3 Suck away a liquid from the tank to level of 10 mm.
Sequence of removal of air
1. A support the back right.
2. A support the back left.
3. A support the forward right.
4. A 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 brake pedal so that to feel resistance slowly.
8 Repeat the described procedure so much time, how many it is necessary that the leaving liquid did not contain bubbles. The fresh liquid is learnt on light colour.
9 Slightly tighten the union. The inhaling moment depends on diameter of a carving: the union in diameter of 7 mm is tightened by the moment 5 Nm, diameter 11 mm the moment 15 Nm.
10 Similarly, in the order specified above, pump out a brake liquid from other supports.
11 After replacement of a brake liquid press a pedal of a brake and check up its free wheeling. It should not exceed 1/3 general courses of a pedal.
12 Cars with Manual transmission: As the coupling drive works on a brake liquid, liquid replacement in coupling hydrosystem is made in the way described above.
13 Before replacement of a brake liquid fill it in the tank to noted level.
14 Screw a cover on the tank.
15 In summary brake some times on road with a rare traffic. Thus at least once execute full braking at which works ABS, in particular, on a ground. Work ABS is felt on pulsations of a pedal of a brake.
