The brake pads must be removed as follows.
Place the front side of the vehicle on jack stands.

Remove both screws and remove the cylinder body.

To do this, take the bottom side of the case and pull it up in the direction (arrow).

Remove the brake shoes from the guide shafts. The mounting springs will remain on the upper and lower sides of the brake saddle support.
Using a piece of wood, carefully push the piston back into the hole. Since this may cause brake fluid to leak out, you should suck out some fluid from the master cylinder reservoir.
Measure the thickness of the brake pads. If they are worn out and the thickness of the pads together with the metal plate has decreased to 7 mm, they should be replaced as a set.
Clean the released brake seat support and cylinder from brake dust. At the same time, check the humidity: there should be no signs of leakage in the brake cylinder. Otherwise, the brake seat cylinder should be repaired or a new cylinder should be installed.
When installing brake pads, proceed as follows.
The brake shoe with a larger working surface is placed on the outside.

Mount both retaining springs on the brake saddle support. When replacing brake pads, always install new springs.

Carefully insert the brake seat cylinder so that both screws can be screwed in at once. If you push the cylinder forward, the mounting springs may become deformed.
Tighten both screws alternately to a torque of 25 Nm.

Perform all other operations in reverse order. If necessary, correct the brake fluid level in the master cylinder reservoir. Press the brake pedal several times to bring the brake pads closer to the disc. Tighten the wheel nuts to a torque of 110 Nm.
