It is recommended to use a special key to tighten the brake pipe mounting nuts.
The brake hose must be elastic, without tears or cracks, and firmly sealed in the tips. The threads of the hose tips must not be damaged. If the hose swells when you press the brake pedal, then the cord threads are torn. If any of these defects are detected, the hose must be replaced.
If the tip "sticks", you can cut the hose and then unscrew its ends from the wheel cylinder nipple and brake pipe. However, to install the hose, you will have to remove the caliper to screw it onto the hose.
1. Using a second wrench to hold the end of the hose by the hexagon, unscrew the end of the tube.
2. Disconnect the hose from the tube.
3. Plug the hole in the tube with the protective cap of the air release valve.
4. Inspect and replace the broken spring clip.
5. Remove the brake hose seal from the bracket on the strut.
6. Unscrew the hose from the wheel cylinder fitting.
7. Please note: The tip has a copper sealing ring. Replace the tightly compressed ring.
8. Install the new hose in the reverse order of removal. Make sure it does not twist. There is a colored strip on the hose for control.
9. Replace the rear brake hose in the same way. After replacing the hoses, bleed the brake hydraulic system.
