11.7. Removal and installation of brake lines

Remember that the brake fluid merged from a path is not subject to reuse!

Rules of service of lines of a hydraulic path


1. Check of a condition of metal and rubber brake lines has to be made on a regular basis according to the schedule of routine maintenance of the car (see the Head Nastroyki and routine maintenance). Attentively examine all lines of a brake path on existence of mechanical damages and signs of development of leaks. Deformation of tubes can lead to violation of their passability that in this case is fraught with violation of efficiency of functioning of the brake system (up to full refusal of the corresponding contour). Rubber hoses should be checked for existence of cracks, cuts, attritions, swellings and other signs of destruction of protective fittings.

2. At a detachment of brake lines special attention should be paid to respect for purity, - before undocking carefully smooth out the surface of nipple sockets (use a brush and special cleaners). Right after a detachment of lines stop up their open ends in order to avoid hit to the highway of dirt and moisture.

3. Before installation replaceable sections should be washed out pure brake fluid.



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 car also establish to Poddomkratta it on props.
3. For the purpose of ensuring access to the brake line needing service remove the corresponding wheel.
4. Carefully (with application of a special cleaner) wipe the nipple sockets and surfaces surrounding them which are subject to a detachment.
5. Prepare the drain capacity and rags for collecting the spilled brake fluid.

6. Undocking of the nipple socket is made by means of two keys, one of which (cap with a cutting head) is put on a nipple nut, and the second is used for keeping of a reciprocal part of a joint from a provorachivaniye. Application of two keys will allow to avoid extremely undesirable deformations of the hydraulic line and damage of the union.

7. Any, used in nipple sockets sealing washers are subject to replacement without fail!

8. Having moved drain capacity, disconnect the second end of the served section of a brake path (also use two keys).

9. Release the disconnected line from intermediate clamps and remove it from the car. At once to a zakuporta the open ends of the disunited path.



1. At installation of replaceable section of the brake line it is necessary to begin with connection of that its end which is more removed from the main cylinder. At a nazhivleniye of a nipple nut track that there was no its perekashivaniye fraught with failure of a carving.
2. Tightening of nipple sockets is also made by means of two keys.
3. Having established replaceable section, make sure that it does not adjoin to moving elements of the suspension bracket/helmsman of the drive (removal not less than 13 mm is considered safe).
4. Track that the line was fixed in all provided intermediate clamps / basic arms.

At installation of flexible brake hoses you watch that they were not overwound.

5. Install all components which were removed for the purpose of ensuring access, then lower the car on the earth.
6. Add in the GTTs tank necessary amount of fresh hydraulic liquid (see the Head Nastroyki and routine maintenance), and pump over the brake system (see the Section Pumping of the Brake System).
