Replacing the front brake pads
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. You should also update the pads when replacing the brake disc, oiling the pads or the presence of deep grooves, cracks and chips on them. 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. 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 …

On a note
The brake pads of the front wheels must be changed only as a set - all four pieces on both front wheels. The same applies to the rear axle. Replacing the pads of only one brake mechanism can lead to the car being pulled to the side with a sharp slowdown.
Replacing the rear brake pads
We replace the pads in the case of the maximum allowable wear of their pads or the drum of the brake mechanism of the rear wheel. The pads must also be replaced when oiling the pads, the presence of deep grooves and chips on them, or if the pads are peeled off the base of the pads. We show the replacement of the pads on the left rear wheel. Remove the decorative wheel cap.

We check the technical condition of the parts and clean them. Before installing new pads, we clean the threads of the spacer tip and ratchet nut and apply a thin layer of grease to the threads. Install the new brake pads on the rear wheel in the reverse order. After mounting the pads, we set the mechanism for automatically adjusting the gap to its original state. To do this, by changing the length of the spacer strip, set the distance between the outer surfaces of the linings of the front and rear pads 202.45 ± 0.25 mm.
