· Tie the caliper to the suspension or to the   body with a wire without disconnecting from   the brake hose to prevent depressurization   of the brake system.
· Make sure that the brake caliper is not   hanging on the brake hose.
· Don't press the brake pedal after the brake   caliper has been removed. As a result, the   piston can fall out from the brake cylinder,   and brake fluid leakage and depressurization   of the system may occur.
