Height of Cam Plate and Ball
1. Measure the dimensions of the cam plate with the ball installed.
2. If the measurement is less than the allowable limit, replace the
cam plate and balls.
3. Inspect the ball holes of cam plate for uneven wear. If the
uneven wear is found, replace it.

Brake Piston Flatness
1. Place the brake piston on flat surface (surface plate) and
determine if a 0.3 mm (0.012 in.) feeler gauge will fit
underneath.
2. Check this at four points on a diagonal line.
3. If it will fit, grind in a circular motion with sandpaper or replace it.
4. Inspect the sliding portion of the brake piston and brake case
interior. If damage or wear is found, replace it.
