Note: For tube part numbers, see here or here.
Attention. Brake pipes must not have any kinks, dents or other damage that could lead to depressurization of the brake system. Brake pipes with the above defects must be replaced.
Attention. It is not allowed for the brake pipes to touch other parts except for the mounting points and the noise-insulating upholstery of the front shield.
All brake pipe connections are made with a key "11". For work it is better to use a special key for brake pipe fittings.
Removal
Place the vehicle on a workbench or two-post lift (depending on the location of the brake pipes being replaced on the vehicle), apply the parking brake and turn off the ignition.
Raise the vehicle to a height convenient for performing work.
Before replacing the brake line to the front brake hose, remove the front wheel.
Before replacing the brake pipe, the attachment points to the body of which are located above the gas tank, remove gas tank.
Disconnect the brake pipe from the brake system components (brake master cylinder, ABS hydraulic unit, rear brake pressure regulator, rear brake wheel cylinder, brake pipe, flexible brake hose).
At the connection points with flexible brake hoses, remove the mounting bracket from the brake pipe fitting.
When removing the pipes, install technological plugs into the openings of the brake system (14 mm spanner, brake pipe wrench type 41 08 11 13 f. "Stahlwille", technological plugs).
Remove the brake pipe by releasing it from the brackets securing it to the car body.
For the brake pipes of the rear wheel cylinders, release the pipes from the mounting brackets to the beam and rear suspension arms (flat head screwdriver).
To remove the pipes laid under the bottom of the body, first remove the pipeline screen (replacement head 13, extension and ratchet).
Installation
Caution: When connecting brake pipes to flexible hoses, twisting of the brake hoses is not allowed.

Install the brake system pipes in the reverse order of removal (14 mm spanner, brake pipe wrench type 41 08 11 13 f. "Stahlwille", replaceable inserts 11 type 58 23 10 11 f. "Stahlwille", torque wrench type 50 18 00 04 f. "Stahlwille").
The tightening torque of the brake pipe fittings is 14 Nm (1.4 kgf·m).
If it was removed, then:
- install pipeline screen (replacement head 13, extension and ratchet);
- install the gas tank.
- install the front wheel.
Bleed the brake system (see here).
Check the efficiency of the service brake system.
