You need to inspect the fluid level in the brake master cylinder reservoir. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove the brake fluid to the midway point before proceeding. Next, you can raise and support the vehicle, remove the tire and wheel assembly, compress the
Brake Caliper pistons and clean all dirt and debris from the brake caliper and fittings. Then you can remove the brake hose from the brake caliper, and discard the 2 copper brake hose gaskets, the brake caliper guide pin bolts from the brake caliper, and the brake caliper from the caliper mounting bracket.
