To unscrew the nuts of the pipelines, use special wrenches for brake pipelines, since the nuts are heavily tightened and usually corroded, as a result of which, when using ordinary wrenches, the edges of the nuts are crushed.
Note: The operation is shown on the example of a pipeline connecting the ABS hydro-electronic unit with a hose attached to the working cylinder of the brake mechanism of the right rear wheel. The remaining pipelines are removed in almost the same way, the only difference is in the places where their holders are attached to the body.
1. Drain the brake fluid
2. Unscrew the nut securing the pipeline to the ABS hydro-electronic unit going to the brake hose attached to the working cylinder of the brake mechanism of the left front wheel (for clarity shown with brake master cylinder removed).
3. Turn out a bolt of fastening of the holder of pipelines and remove the holder. Remove the pipes from the plastic holder socket at the front of the body base.
4. Remove the pipeline from the holders on the base of the body (pic. 9.8) and take it off.

6.... and remove the pipeline.
7. Install the new pipeline in the reverse order of removal.
8. After replacing the pipeline, bleed the air from the brake system (see «Brake Fluid Replacement»).
