2. Jack up the rear of the vehicle and place it on axle stands.
3. Remove the brake drums.
4. Disconnect the drive cable from the brake mechanism.
5. Unhook the upper return spring with pliers.
6. Remove both anchor pins. To do this, turn the spring plate with pliers until the pin head comes out through the slot.
7. Press the lever indicated by the arrow against the inside (see illustration) and at the same time press down the small toothed segment (left arrow). Remove the brake pads.
10.7 Removing the brake pads. Press the lever against the end of the axle. The bottom arrow indicates the serrated segment
8. Remove the push rod at the top once it is free.
9. Set the gear segment to its original position (when the lever is moved inward, the segment will pop up) and turn the brake shoes with lever and toothed segment 90°so that the lower return springs can be unhooked with a screwdriver (see illustration).
10.9 Removing the brake pads
10. A rubber band must be wound around the piston so that the piston does not slip out of the brake cylinder. Wire clamps can also be used for this purpose.
11. Thoroughly clean all parts, including the shield. If gasoline is used for flushing, it should not get on the rubber boots of the wheel cylinder piston. In case the coating is worn to a thickness of 0.5 mm below the rivet heads (or the thickness of the pads together with the material of the brake pads themselves is 2.5 mm), install new brake pads.
12. The pads can be changed individually, but it's still better not to do this.
13. If the wheel cylinder piston shows signs of leakage, it must be replaced as described in chapter 12.
