Unscrew the attaching bolt on the brake hose to disconnect it from the caliper. Plug up the line with a small piece of rubber. Toss out the copper washers, as you will need to use new ones upon assembly.
Disconnect the caliper guide pin bolts securing the caliper to the steering knuckle. Slide the caliper slowly away from the knuckle. Slide the caliper’s opposite end out from under the knuckle’s machined abutment.
Clean the abutment surfaces and lubricate them multipurpose lubricant. Run a mist of water over the surface and use a damp rag to clean them. Never dry clean brake parts because of asbestos risk.
