During each vehicle maintenance, visually inspect the condition of the brake hoses. Hoses that are worn, bulging, cracked or delaminate are replaced immediately. Brake hoses must be replaced after 125,000 km of mileage or after 5 years of operation.
To complete the work you will need:
- special key for brake pipe fittings;
- reliable car stand.
Removal
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Remove the wheel (see "Wheel - replacement").
3. If the vehicle is equipped with brake pad wear sensors, disconnect the sensor wire tip from the wiring harness connector.
4. Remove the brake hose from the bracket on the suspension strut.
5. Clean the brake hose tips from dirt and treat the brake pipe fitting with penetrating lubricant.
Warning! When performing the following operation, make sure that when unscrewing the nipple, the tube does not rotate with it. If the tube is "stuck" in the nipple, replace it.
6. Hold the upper end of the brake hose from turning with an open-end wrench by 15 mm, using a special key, unscrew the brake pipe fitting.
7. To prevent brake fluid from leaking out of the system, place a protective cap on the end of the tube for bleeding the working brake cylinder.
8. With an open-end wrench by 15 mm unscrew the lower end of the brake hose.
The connection of the hose to the working cylinder is sealed with a copper ring, which cannot be reused.
Installation
1. Place a new sealing ring on the lower end of the hose, screw the end into the hole in the brake cylinder body and tighten.
2. Screw the brake pipe nipple into the upper end of the brake hose and tighten it, preventing the hose from twisting. The absence of twisting of the brake hose is determined by the colored strip applied to it.
3. Install the hose into the suspension strut bracket.
Bleed the brake system (see "Hydraulic brake drive - bleeding") and make sure that the connections of the tips of the new brake hose are tight.
