Attention! The pads are changed only as a set for one axle. When cleaning the pads, remove dust and dirt by wiping with a rag soaked in alcohol; blowing is prohibited.
1. Raise the front of the vehicle and support it on stands.
2. Remove the front wheels.
3. Pull the caliper towards you so that the piston enters the cylinder, monitoring the fluid level in the reservoir.
4. If necessary, press the piston in with a clamp.
5. Unscrew the caliper pins (insoles).
6. Remove the caliper from the disc.
7. Please note that the outer shoe may remain on the bracket.
8. After removing the caliper, do not press the brake pedal.
9. Secure the caliper so that it does not hang from the hose.
10. Remove the adjusting shims.
11. Remove the pads.
12. Remove the brake shoe retainers.
13. Check the thickness of the friction linings.
14. If the thickness of at least one pad is less than the norm, or the pads are heavily contaminated, then replace all pads in a set on one axle.
15. Find and eliminate the cause of contamination.
16. It is prohibited to rearrange the pads to compensate for wear.
17. If the condition of the pads is satisfactory, clean them, removing any ingrained dirt and large particles.

18. Clean the mating surfaces of the pads in the caliper and bracket.
19. Before assembly, check the freedom of movement of the pins in the bracket and support, as well as the integrity of the rubber boots.
20. Check the condition of the piston seals, the presence of corrosion on the piston and signs of leakage.
21. If the pads are to be changed, the piston should be moved to provide space for the pads.
22. When moving the piston, monitor the fluid level; excess fluid should be removed with a rubber bulb or syringe.
23. Lightly lubricate the brake pad plates, linings and spring clips with a special anti-noise lubricant.
24. Install the brackets, pads and spacers into the caliper bracket. The outer pad is installed into the bracket and the inner pad is installed into the caliper.
25. Make sure the inner shoe retainer engages with the piston.
26. Install the caliper, lubricate the caliper pins with a fixing compound and tighten.
27. Tighten the pins to the specified torque.
28. Check the freedom of movement of the caliper using your fingers.
29. Repeat the above steps for the brake of the other wheel.
30. Press the brake pedal several times.
31. Install the wheels, lower the car.
32. Check the fluid level.
33. Check the operation of the brakes before leaving.
