Unscrew the union nut and remove the tube.
Close the joints with suitable plugs.
Install the new tube, if possible, in the same place.
When connecting the pipe, wet the conical surface with a few drops of brake fluid and tighten the nut to a torque of 12-15 Nm.
Install the new hose so that it does not twist or stretch, secure with a torque of 12-15 Nm.
After installation, check on an unloaded wheel (car raised) to see if the hose follows all wheel movements and does not rub against other parts.
Caution: Do not allow the brake hose to come into contact with oil or fuel, do not paint or apply coatings used to protect the underbody.
Remove air from the hose.
With the vehicle standing on its wheels, turn the wheels from one extreme position to the other and check whether the hose follows all the movements of the wheel without any friction against other parts.
Attention, please perform a safety check:
- Is the brake hose connection tight?
- Is the brake hose secured in the holder?
- Is the air bleed bolt tightened?
- Is the brake fluid level in the expansion tank sufficient?
Check for leaks with the engine running. To do this, press the brake pedal with a force of 200-300 N (20-30 kg) and hold it for about 10 seconds. The pedal should not fall through. Check the tightness of all connections.
Finally, make a few braking attempts on a street with light traffic.
