Inspection
1. After every six months, after raising the car and securely securing it to supports, you should carry out a preventive inspection of the flexible brake hoses connecting the steel lines of the brake system to the front and rear brakes. Make sure there are no cracks, fraying of the braid, leaks, swelling or other signs of damage to the hoses. Hoses are the most critical and vulnerable elements of the system, so inspection should be carried out especially carefully and fully. To carry out high-quality visual inspection, you must use a flashlight and a mirror. If any of the above defects are found on the hose, replace it.
Replacement
Front brake hoses
2. Loosen the wheel nuts, raise the vehicle and install vertical supports. Remove the wheel.
3. Unscrew the fitting located on the bracket from the hose (see illustration). To prevent the ribs of the fitting nut from rounding, use a spanner. In this case, it is necessary to fix the hose tip with another wrench to prevent the bracket from turning.
7.3. Using a spanner wrench, unscrew the brake pipe fitting...
4. Unscrew the bolt from the bracket and disconnect the hose from it (see illustration).
7.4....then unscrew the bolt and disconnect the hose from the bracket
5. Unscrew the bolt of the inlet fitting located on the hose on the caliper side, then disconnect the hose from the caliper. It should be noted that there are two copper sealing washers on both sides of the fitting (see illustration 4.2) - these elements must be replaced after disconnecting the hose.
6. When installing the hose, it is necessary to connect the inlet fitting to the caliper and secure it with a bolt, and also install new copper washers. Tighten the inlet fitting bolt to the required torque.
7. Route the hose back to its original route and make sure it is not kinked. Tighten the hose bracket bolt securely. Connect the brake pipe fitting, starting with finger tightening. Tighten the fitting securely with a wrench.
8. Bleed the caliper (see subsection 8).
9. Install the wheel and secure it with nuts, lower the vehicle onto the supporting surface and tighten the wheel nuts to the torque specified in Chapter 1 specifications.
Rear brake hoses
10. Raise the rear of the vehicle and install vertical supports. Chock the front wheels to prevent the vehicle from rolling.
11. Unscrew the fitting located on the bracket from the hose (see illustration). To prevent the ribs of the fitting nut from rounding, use a spanner. In this case, it is necessary to fix the hose tip with another wrench to prevent the bracket from turning.
7.11. Using a spanner, unscrew the fitting located at the end of the brake hose...
12. Unscrew the bolt from the bracket and disconnect the hose from it (see illustration).
7.12....then remove the bolt that secures the connector to the chassis element
13. Unscrew the bolt of the inlet fitting located on the hose on the caliper side, then disconnect the hose from the caliper. It should be noted that there are two copper sealing washers on both sides of the fitting (see illustration 4.2) - these elements must be replaced after disconnecting the hose.
14. When installing the hose, it is necessary to connect the inlet fitting to the caliper and secure it with a bolt, and also install new copper washers. Tighten the inlet fitting bolt to the required torque.
15. Route the hose along the original route and make sure it is not kinked. Tighten the hose bracket bolt securely. Connect the brake pipe fitting, starting with finger tightening. Tighten the fitting securely with a wrench.
16. Bleed the caliper (see subsection 8).
17. Install the wheel and secure it with nuts, lower the vehicle onto the supporting surface and tighten the wheel nuts to the torque specified in Chapter 1 specifications.
Metal pipes of the brake system
18. When replacing tubes, make sure that the technical requirements of the replacement parts are met. Do not include copper pipes in the brake system. Replacement steel tubes should be purchased from branded auto stores or other reputable sources.
19. Prepared tubes with flared ends and installed connectors are available for sale. Also, these tubes are curved accordingly.
20. When installing a new brake pipe, make sure that it is securely fixed in the bracket and is not located in close proximity to moving or heating elements of the car. The distance between parallel brake hoses must be at least 6 mm.
21. After completing the installation procedure, check the fluid level in the master cylinder reservoir and top up if necessary. Bleed the brake hydraulic system as described in subsection 8 and check the operation of the brakes before driving onto the roadway.
