To perform the work you will need a special key for 13 mm brake system fittings and new brake fluid.
It is convenient to carry out the work on an inspection ditch or overpass.
Note: Tubes of different lengths and shapes are used to connect the main brake cylinder, ABS hydraulic unit and wheel brake mechanisms. The tubes are secured in holders on the body...
...and the rear axle beam. Connecting nipples are installed at the ends of the tubes.
Sequence of execution
1. To replace the tube, prepare the car for the work and, if necessary, install it on an inspection ditch or overpass (see "Preparing the car for maintenance and repair").
2. Using a 13 mm wrench for pipe fittings, unscrew the tube fastening fittings.
3. Disconnect the tube from the holders (see above, "Note") and remove it. To replace the tube on the bottom of the car, remove the protective shield of the tubes.
4. Install the tube in reverse order. Tighten the brake pipe fittings to a torque of 14 Nm.
5. Bleed the brake system (see "Hydraulic brake drive - bleeding") and make sure that the connections of the new brake pipe are tight.
