1. Check the condition of the flexible hydraulic hoses leading to each front brake pad, as well as to the rear axle. If they are swollen, damaged or chewed, they should be replaced.

2. Clean the top of the brake cylinder reservoir cap and place a piece of tape over the hole. This should prevent hydraulic fluid from spilling out during subsequent operations.

3. To remove the front flexible hose, wipe off any dust from the fitting and clamps, and unscrew the fitting nuts from the ends of the metal tubes.

4. Pull out the mounting plate and disconnect the hose from its bracket.

5. Remove the rear flexible hose by unscrewing the fitting nut from the pressure regulating valve and then unscrewing the hose from the three-way connector.

6. Installation in both cases is carried out by performing the above steps in reverse order. You will need to bleed the brake system as described in Section 12. If you only removed one hose, then you can bleed only the front or rear brake hydraulic lines. Don't forget to remove the adhesive tape from the tank lid.

7. When finished, make sure that the hoses do not rub against the tires when turned fully to the stop. If this situation occurs, you can change the position of the hose by releasing the mounting plate and the nipple nut from the bracket and turning the hose no more than a quarter of a turn.

8. Clean steel brake lines at regular intervals and check for rust and dents that may be caused by flying stones.

9. Check the mounting clamps, which should be insulated to prevent wear on the tube surface. Bend the clamp tabs if necessary to ensure they hold the brake lines securely and prevent them from rattling or vibrating.



10. Check that the tubes do not touch adjacent components and do not rub against various parts of the vehicle. If this situation occurs, bend the impression tube to move it away.

11. Even though the tubes have a special coating, any section can suddenly rust, and then the entire section must be replaced. When installing new tubes, use the old ones as a reference; do not bend the tubes more than necessary.

12. After replacing and/or connecting pipes, the entire hydraulic brake system must be bled.
