Wheel Cylinder: Testing and Inspection

REAR DRUM BRAKE LININGS AND REAR WHEEL CYLINDERS (INSPECT FOR WEAR AND LEAKS) [VEHICLES WITH REAR DRUM BRAKE]

BRAKE LINING THICKNESS CHECK

CAUTION
^ Whenever the shoe and lining assembly is replaced, replace both RH and LH assemblies as a set to prevent the car from pulling to one side when braking.
^ If there is a significant difference in the thickness of the shoe and lining assemblies on the left and right sides, check the sliding condition of the piston.

1. Remove the brake drum.





2. Measure the thickness of the brake lining at the area with the most wear.

Standard value: 4.0 (0.16 inch)
Minimum limit: 1.0 mm (0.04 inch)

3. Replace the shoe and lining assembly if the brake lining thickness is less than the limit or if it is not worn evenly.

REAR WHEEL CYLINDERS CHECK





1. Remove the brake drum.
2. Check if the liquid leaks from around the boot of the wheel cylinder visually or by touching with fingers.
