Removal
Loosen the wheel nuts of the vehicle while it is parked on the ground.
Raise the front of the vehicle and remove the front wheel, first marking the position of the disc relative to the hub.
Attention: It is not allowed to change the brake pads from the pair on the clear side to the inner one and vice versa, as well as from the right wheel to the left and vice versa. Be sure to change all pads on one axle at once. If the pads are to be re-installed, they should be marked.
Bend back the retaining washer on the caliper mounting bolt.
Pull the brake caliper outward with your hands, thereby pushing the piston in.
Remove the lower brake caliper pin.
Pull the caliper up and hang it on the wire from the shock absorber spring.
Remove the brake pads.
Installation
Caution: When the pads are removed, do not press the brake pedal, otherwise the piston will come out of the housing.
Clean the guide surface and brake pad mounting areas with a soft metal brush or wipe with a cloth soaked in alcohol. Do not use solvents containing mineral oils or sharp tools.

Before installing the pads, check the brake disc for grooves. A disc with deep grooves must be replaced (see photo).
Measure the thickness of the brake disc.
Check the integrity of the dust cover and protective cuffs of the brake caliper. A damaged boot must be replaced, as penetrating dirt will quickly depressurize the caliper. To do this, the brake caliper must be removed and disassembled.
Press the piston with a wooden block (with a hammer handle), while doing this, do not allow the piston to become skewed or damage the piston surface and dust boot.
Caution: When the piston is depressed, brake fluid flows from the brake cylinder into the expansion tank. Observe the brake fluid in the reservoir and remove some of the fluid if necessary.
To remove liquid, you can use a rubber bulb or a plastic bottle. Do not use food grade utensils. Under no circumstances should you suck out brake fluid through the hose with your mouth. After replacing the pads, the brake fluid level in the reservoir should not exceed the MAX mark, since the fluid expands when heated. Leaking liquid can destroy paint and cause corrosion.
Caution: If the brake pads are heavily worn, check that the piston moves easily. To do this, insert a wooden block into the caliper and have an assistant slowly press the brake pedal. The piston should move in and out easily. During testing, a different caliper may be installed. Be careful not to let the piston come out completely. If this happens, it is necessary to bleed air from the brake system.
The following work step is optional: to prevent brake squealing, the back of the pads can be coated with a special lubricant. In this case, the lubricant should not get onto the working surfaces of the brake disc. If contact occurs, wipe off immediately and rinse the pad with alcohol.
After inserting the pads with outer linings (if any) on both sides, lower the brake caliper. Tighten the bottom finger.
Install the wheels, observing the marks made during removal. Lower the vehicle and tighten the lug nuts in a cross pattern.
Caution: Press the brake pedal sharply several times until you feel a noticeable resistance.
Check the brake fluid level in the expansion tank, if necessary, add fluid to the MAX mark.
Allow the new brake pads to break in by braking the car several times at a speed of 80 km/h to 40 km/h by lightly pressing the brake pedal. Allow the brakes to cool between successive braking applications.
Warning: Do not brake abruptly unless necessary during the first 200 km.
