Withdrawal
Raise the rear of the car and remove the wheel.
Unscrew the adjusting eccentrics and loosen the parking brake cable.
After unscrewing the mounting bolts, remove the brake drum.
Installation
Examine the brake drum. Check the radial runout of the drum, which should not exceed 0.05 mm. If there are deep grooves or excessive ovality on the working surface of the drum, bore the drum on the machine. Then, also on the machine, grind the drum with abrasive fine-grained bars.
Reinstall the brake drum. Adjust the clearance between the brake shoes and the drum and the parking brake system.
