11 — the Piston with a sealing cuff
12 — the Lock cover
13 — Assembly of primary piston
14 — Assembly of the secondary piston
15 — Models without ABS
16 — Models with ABS

 The failed GTTs is subject to replacement. Manufacturers do not recommend to make attempts of carrying out recovery repair of the main brake cylinder.



1. Disconnect a negative wire from the battery.

 If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!

2. The design of the main brake cylinder is presented on an illustration.
3. Disconnect an electrical wiring from the sensor switch of level of brake fluid.
4. Pump out from the GTTs tank as the bigger amount of the liquid which is in it is possible (use the syringe or a rubber pear).
5. Enclose rags under nipple connections and prepare caps or plastic bags for a blockage of the open ends of brake lines for the purpose of prevention of hit in system of dirt.

 Brake fluid is among aggressive chemical compounds and at contact with body panels destroys a paint and varnish covering. Before starting implementation of the procedure cover wings and the panel of a front of the car with special covers, or just old blankets. By means of a special cap key with a cutting head weaken nuts of nipple knots of connection to GTTs of brake lines.

6. Having slightly delayed outside, separate brake lines from unions of the main cylinder. At once to a zakuporta open ends of tubes.

7. Release two fixing nuts and separate the main cylinder from assembly of the brake amplifier. Remove the cylinder from fixing hairpins and take it from a motive compartment (try not to spill the hydraulic liquid filling assembly on the painted body panels). Remove and will throw out old sealing laying of landing of GTTs on the block of the vacuum amplifier of brakes, - at assembly laying is subject to replacement without fail.

About Fixing nuts



1. Before installation new GTTs needs to be pumped over on a workbench. For convenience clamp a landing flange of the cylinder in a vice with soft sponges. Further it is necessary to manipulate at the same time the piston in the cylinder and to watch a stream of the brake fluid which is pushed out via the final union.
2. Connect to the GTTs final unions couple of tubes from special set for pumping (ask in shops of automobile accessories).
3. Fill in in the tank fresh brake fluid of the required grade (see the Head Nastroyki and routine maintenance).
4. Slowly push pistons in the cylinder (it will be most convenient to use the big screw-driver with a crosswise sting), - air has to begin to go out of delivery cameras in the tank. At the same time it is important that the ends of both tubes were completely shipped in the brake fluid which is in the tank to exclude probability of a podsasyvaniye of air back in the cylinder at an otpuskaniye of pistons.
5. Continue pumping until the liquid which is pushed out through tubes completely is not exempted from air bubbles.
6. Serially disconnect tubes, at once corking the open ends of entrance openings. Close the GTTs tank a cover.
7. Put on GTTs hairpins on assembly of the vacuum amplifier and until only by hand, tighten fixing nuts.
8. Screw unions of brake lines in the cylinder. As the cylinder is not fixed finally yet, its situation can be corrected slightly for the purpose of simplification of the procedure of a vvorachivaniye of unions - try not to strip a thread.
9. Tighten with the required effort of a nut of fastening of GTTs, then densely delay nipple connections.
10. Fill in fresh brake fluid in the GTTs tank and pump over hydraulic system (see the Section Pumping of the Brake System). Pumping of GTTs on the car (if did not do it on a workbench) will require the help of the assistant who will manipulate a pedal of a foot brake. Ask the assistant to squeeze out several times a pedal, then to record it in the lower situation. Weaken a nipple nut, producing air mix with brake fluid from the cylinder. Repeat the procedure until the pushed-out liquid completely is not exempted from air bubbles. Working in a similar manner, pump over the second union.

 You hold near at hand pure rags for the purpose of immediate removal of traces coming on the painted body surfaces of brake fluid.

11. Before starting operation of the car, make sure of serviceability of functioning of brakes.
