Brake pads must be replaced if the linings are worn, the linings are not firmly connected to the base, the working surfaces are oily, or there are deep grooves or chips.
Caution! Replace front brake pads only as a set of 4. (two on each side). Before replacing the brake pads, check the brake fluid level in the master cylinder reservoir. If the level is close to the upper mark, you need to pump out some of the fluid: after replacing the worn pads with new ones, the fluid level will rise.
You will need: keys "13", "17", screwdriver.
1. Remove the left front wheel.
2. Unscrew the bolt securing the lower guide pin of the caliper...
3. ...and lift the caliper up.
4. Remove the outer brake shoe from the guide.
5. Lower the caliper into place and depress the slave cylinder piston by inserting a screwdriver between the caliper and the brake disc and sliding the caliper outward.
6. Fold the caliper upward and remove the inner brake pad from the guide.
Note. Every time you replace the brake pads, be sure to check the condition of the protective rubber boots of the guide pin, as well as the movement of the caliper relative to the brake pad guide. If movement is difficult, lubricate the caliper guide pins with grease. To do this...
...remove the guide pin...
...lubricate it with consistent grease and put grease into the inner cavity of the boot. Install the pin into the pad guide in the reverse order of removal. If signs of rubber aging appear, replace the protective boots of the guide pins.
7. Install the brake pads into the guides in the reverse order of removal. To prevent the caliper guide pin mounting bolt from loosening on its own, lubricate its threads with anaerobic thread locker before installation. Tighten the bolt to a torque of 34 N·m (3.4 kgf·m).
8. Press the brake pedal several times to bring the brake pads to the disc.
9. Install the wheel.
10. Similarly, replace the brake pads of the right wheel brake mechanism.
11. Check and, if necessary, restore the brake fluid level in the master cylinder reservoir.
Note. After replacing worn brake pads with new ones, do not rush to drive on busy highways. It is possible that during the first intensive braking you will be unpleasantly surprised by the low efficiency of the brakes, despite the fact that the original pads are installed. Brake discs also wear out, and new pads only touch them with the edges, practically without braking. Choose a quiet street or a passage without cars and brake smoothly several times so that the pads rub in and begin to fit over the entire surface. At the same time, evaluate the efficiency of the brakes.
Try not to brake sharply for at least the first 100 km. If the brake pads are too hot, the top layer of their linings will burn and the brakes will not be as effective as possible for a long time.
