- if the thickness of the pads on the left and right is significantly different, check the piston for slip.
Remove the brake drum. Check the thickness of the pad at the thinnest point. Standard value: 5.0 mm, wear limit: 1.0 mm. Replace the pad and pad assembly if the pad thickness is less than the limit or if it is worn unevenly.
Checking the inner diameter of the drum brake
Remove the brake drum. Measure the inside diameter in at least two places. Standard value: 295 mm, wear limit: 297 mm. Replace the brake drums and pad assembly if the wear exceeds the wear limit or if the drum is worn unevenly.
Checking the contact surface of the brake drum and lining
Remove the brake drum and lining assembly. Apply chalk to the inside of the drum and run the rubber over it. If the contact is uneven, replace the brake drum or shoe and lining assembly. After checking, clean the parts from chalk.
