Check of a condition and replacement of brake lines and hoses

Approximately time in half a year, having lifted the car, check all flexible hoses connecting steel tubes of hydraulic contours to brake mechanisms of wheels, on existence of cracks, signs of damage of a protective cover, traces of leakages of liquid, swellings and other damages. Hoses are a critical and most vulnerable component of brake system therefore their survey should be made with all care - use a pocket small lamp and a small mirror. At identification of any doubtful signs the suspected hose is subject to replacement.


Flexible brake hoses


1. Weaken nuts of fastening of wheels, поддомкратьте the car and establish it on props. Remove wheels.

2. On a frame arm release the shtutserny socket of connection of a flexible hose to the rigid brake line.

 Otpuskaniye of nuts of shtutserny sockets in order to avoid a rounding off шлицов should be made them by means of a special cap natural a cutting head.

3. By means of flat-nose pliers take an U-shaped clamp and liberate a hose from an arm on a car frame.
4. For a hose detachment from a support of the brake mechanism turn out a hollow bolt of the shtutserny socket. Pay attention that from both parties of the socket it is established on a copper sealing washer which at assembly are subject it is replaced without fail.
5. Remove an U-shaped clamp and liberate a hose from an arm on a suspension bracket rack.
6. For installation of a hose pass its corresponding union in an arm on a suspension bracket rack, then screw a hollow bolt of the shtutserny socket on a support (do not forget to replace sealing washers). Having made sure that the lock uvula of the shtutserny socket got to a reciprocal opening on the support case, tighten a hollow bolt with demanded effort.
7. Push the metal holder in an arm on a rack and latch an U-shaped clamp. Make sure that the hose is not overwound on a site between a support and a rack arm.
8. Pass a hose in an arm on a car frame (again try not to allow twisting) and connect it to the union of the metal line. Establish a clamp and an E-shaped lock ring (at the corresponding complete set), then strongly tighten the socket.
9. Pump over a brake support (see. Section Pumping of brake system).
10. Establish to the place of a wheel, lower the car on the earth and tighten nuts of fastening of wheels with demanded effort (see. Head of Control and routine maintenance).

Metal brake lines


1. At replacement of rigid brake lines it is necessary to give particular attention to selection of replaceable components. At all it is not necessary to establish to the hydraulic highway of brake system the copper tubes, not capable to sustain efforts developed in contours. Try to get firm steel lines in representation offices of the company manufacturer of the car, - it is preferable to buy already cut on length and the sections equipped with shtutserny nozzles.
2. Rigid tubes of hydraulic lines are usually fixed on all length in special clamps. At removal of the line watch, that it was liberated from all clips. Do not forget to replace the failed clamps.
3. At installation of new steel lines watch reliability of their fixing in all provided arms, collars and clips. Do not allow making of tubes excessively close from moving components of a suspension bracket and a steering drive.
4. Having finished installation of new sections of hydraulic lines, check liquid level in the GTTs tank. In case of need make the corresponding adjustment. Pump over brake system (see. Section Pumping of brake system). Before starting operation of the car make sure of serviceability of functioning of brakes.
