We replace the pads in the case of the maximum allowable wear of their pads - the minimum thickness of the pads, including its base, must be at least 6 mm. The pads must also be replaced when replacing the brake disc, oiling the pads or having deep grooves, cracks and chips on them, and also if the pads are peeled off the base of the pads.
Attention! The brake pads of the front wheels must be replaced only with a set - all four pads. Replacing the pads of only one brake mechanism can lead to the car being pulled to the side during braking
If the fluid level in the tank of the hydraulic brake actuator is at MAX, then before installing new pads with a syringe or rubber bulb, we pump out part of the fluid from the tank. This operation must be performed so that when the piston is “recessed” into the wheel cylinder of the brake mechanism during the installation of new pads, fluid does not leak out from under the tank cap.
Remove the front wheel. Before installing new pads, it is necessary to move the piston of the wheel cylinder to the inside of the cylinder as much as possible. To do this, by inserting a screwdriver with a wide blade through the hole in the caliper between the base of the outer block and the caliper and leaning it on the caliper …

Similarly, replace the pads on the other side of the car. After replacing the pads, press the brake pedal several times to set the gaps between the pads and discs. We check the fluid level in the tank and, if necessary, bring it to normal.
