During each vehicle maintenance, visually inspect the condition of the brake hoses. Hoses that are worn, bulging, cracked or delaminating must be replaced immediately. Brake hoses must be replaced after 125,000 km or after 5 years of operation.
To perform repair work on replacing the brake hose, you will need:
- special key for brake pipe fittings;
- reliable car stand.
Removal
1. We prepare the vehicle for work (see points 2b and 4 "Preparing a car for maintenance and repair").
2. If the vehicle is equipped with brake pad wear sensors, disconnect the sensor wire tip from the wiring harness connector.
3. Remove the brake hose from the bracket on the front suspension strut.

4. Clean the brake hose tips from dirt and moisten the brake pipe nipple with WD-40 penetrating lubricant.
Warning: When performing the following work, be sure to ensure that the brake pipe does not rotate with the nipple when unscrewing it. If the brake pipe is stuck in the nipple, replace it.
5. Holding the upper end of the brake hose from turning with a 15 mm open-end wrench, use a special wrench to unscrew the brake pipe nipple.

6. To prevent brake fluid from leaking out of the vehicle's brake system, place a protective cap on the end of the brake pipe for bleeding the working brake cylinder.

7. Using a 15 mm open-end wrench, unscrew the lower end of the brake hose and disconnect it from the brake cylinder body.

The connection of the brake hose to the brake cylinder body is sealed with a copper ring.
Installation
We install the brake hose on the car in the following sequence:
1. Place a new sealing ring on the lower end of the brake 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 without allowing the brake hose to twist. The absence of twisting of the brake hose is determined by the colored stripe applied to it.
3. Bleed the car's brake system (see "Bleeding brakes, replacing brake fluid") and make sure that the connections of the tips of the new brake hose are tight.
