NOTICE: Do not damage the wheel cylinder boot.

6. CHECK REAR DRUM BRAKE INSTALLATION
(a) Check that each part is installed properly.

(b) Measure the brake drum inner diameter and the diameter of the brake shoes. Check that the difference between the diameters is equal to the specified shoe clearance.
Shoe clearance: 0.6 mm (0.024 in.)

NOTICE: There should be no oil or grease adhering to the friction surfaces of the shoe lining or the drum.
