Note: To replace the pads with wear indicators, disconnect the tip of the sensor wire from the wiring harness block.
To complete the work you will need:
- reliable car stand;
- small metal brush.
Removal
1. Prepare the vehicle for work (see "Preparing the car for maintenance and repair").
2. Remove the front wheels (see "Wheel - replacement").
3. Clean the main brake cylinder reservoir from dirt. Remove the reservoir cap.
4. Clean the brake mechanism from dirt.
5. Through the inspection hole in the floating bracket of the caliper, slightly move the brake pads apart so that they move away from the brake disc to the maximum possible distance.

6. Using a slotted screwdriver, bend back the corner of the locking plate of the lower guide pin bolt.
7. Remove the brake hose from the rack bracket.
8. Hold the guide pin from turning with an open-end wrench by 17 mm, key by 13 mm we unscrew its bolt.
9. Raise the movable bracket upwards, turning it on the upper guide pin.
10. Remove the brake pads.
11. Using a small metal brush, clean dirt and rust from the brake pad mounting surfaces.
12. Make sure that there is no leakage of brake fluid from under the brake cylinder cuff.
Installation
1. Install new brake pads in place.
2. Lower the movable bracket down until the hole in the housing aligns with the hole in the guide pin (when lowering the bracket, make sure that the spring tabs of the pads do not become displaced or bent).
3. Screw in and tighten the guide pin bolt.
4. We fix the bolt from unscrewing with the corner of the locking plate.
5. Install the brake hose into the suspension strut bracket.
6. Similarly, we change the brake pads of the brake mechanism of the other front wheel.
7. Press the brake pedal several times to automatically adjust the gaps between the pads and brake discs.
8. Check the brake fluid level in the master cylinder reservoir and, if necessary, top it up to normal.
If the fluid level in the master brake cylinder reservoir is above the "MAX" mark, use a rubber bulb to remove some of the fluid from the reservoir.
Warning! After replacing the brake pads, the braking efficiency will be reduced for the first 100-200 km, be careful!
