Removing
– Force pistons out of brake caliper housing one at a time using
compressed air.
The pistons can only be removed one at a time. Hold the opposite
piston in the caliper housing with piston resetting appliance -a-.
Use blocks of wood or similar -b- to keep the other pistons in
place. Also place a piece of wood -c- against the resetting tool to
prevent the piston from being damaged when it is forced out.
