2. Remove the brake hose from the brake caliper.
3. Remove the brake caliper assembly after removing the plate.
Disassembly
1. Loosen the bracket mounting bolts and remove the bracket.
2. Remove the ring cover using a flat-blade screwdriver.
3. Remove the boot from the piston.
4. Remove the piston by blowing compressed air through the hole in the brake hose pipe.

Examination
1. Inspect the bracket and the inner surface of the cylinder for wear, defects and/or corrosion.
2. Check the piston for wear, defects and/or corrosion.
3. Check the bracket body for wear.
4. Check the brake linings for deformation and oiling, and the metal backing for damage.
5. Check the wear indicator of the pad for defects.
6. Check the brake disc with a dial indicator and micrometer. Rework the disc or replace it if necessary.
