To perform repair work on replacing the brake hose, you will need:
- special wrench for fittings of brake pipes;
- reliable stand for the car.
Removing
1. We prepare the car for work (see paragraphs 2b and 4 "Preparing the car for maintenance and repair").
2. If the car is equipped with brake pad wear sensors, then disconnect the sensor wire tip from the wiring harness connector.
3. Remove the brake hose from the bracket on the front suspension strut.
4. We clean the tips of the brake hose from dirt and moisten the fitting of the brake pipe with penetrating lubricant WD-40.
Warning. When performing the following work, be sure to ensure that when the fitting is unscrewed, the brake pipe does not rotate with it. If the brake pipe is acidified in the fitting, replace it.
5. Holding the upper end of the brake hose from turning with a 15 mm open-end wrench, unscrew the brake pipe fitting with a special key.
6. To prevent the brake fluid from flowing out of the brake system of the car, we put on the end of the brake tube a protective cap for the bleeder of the working brake cylinder.
7. With a 15 mm open-end wrench, unscrew the lower end of the brake hose and disconnect it from the brake cylinder body.
The connection between the brake hose and the brake cylinder body is sealed with a copper ring.
Installation
We install the brake hose on the car in the following sequence:
1. We put a new sealing ring on the lower tip of the brake 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 brake hose to twist. The absence of twisting of the brake hose is determined by the colored strip applied to it.
3. We pump the brake system on the car (see "Bleeding brakes, changing brake fluid") and make sure the connections of the tips of the new brake hose are tight.
