To complete the work you will need:
- special wrench for fittings of brake pipes;
- reliable stand for the car.
Removing
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. If the car is equipped with brake pad wear sensors, then disconnect the tip of the sensor wire from the wiring harness block.
3. Remove the brake hose from the bracket on the suspension strut.
4. We clean the tips of the brake hose from dirt and moisten the fitting of the brake pipe with penetrating grease.
Warning! When performing the following operation, make sure that when unscrewing the fitting, the tube does not rotate with it. If the tube "sour" in the fitting, replace it.
5. Holding the upper end of the brake hose from turning with an open end wrench by 15 mm, unscrew the fitting of the brake pipe with a special key.
6. So that the brake fluid does not flow out of the system, we put on the end of the tube a protective cap for the bleeder of the working brake cylinder.
7. Open end wrench by 15 mm unscrew the lower end of the brake hose.
The connection of the hose with the working cylinder is sealed with a copper ring.
Installation
1. We put a new sealing ring on the lower tip of the hose, wrap the tip into the hole in the brake cylinder housing and tighten it.
2. We wrap the fitting of the brake pipe into the upper tip of the brake hose and tighten it without allowing the hose to twist. The absence of twisting of the brake hose is determined by the colored strip applied to it.
3. Install the hose in the suspension strut bracket.
Bleeding the brake system (see "Hydraulic brake drive - pumping") and make sure the connections of the tips of the new brake hose are tight.
