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.
