A: To remove the brake pads, support the caliper on a clean lint-free cloth on the upper control arm and depress the brake pedal to push the piston out of the bore. Wedge the brake pedal down to prevent fluid loss. Disconnect the flexible Brake Line at the frame bracket and plug the brake line if removing both caliper pistons. Secure the caliper in a vise with soft jaws and remove the dust boot. Work the piston seal out of the groove and discard it. Clean all parts with denatured alcohol or brake system solvent and inspect the caliper bore for imperfections. Use a new boot and seal when reassembling the caliper. Lubricate the caliper bore and piston seal with clean brake fluid or brake assembly lubricant. Attach the dust boot to the caliper and lubricate the outside diameter of the piston. Work the piston into the dust seal and carefully install it in the bore. Ensure the piston is completely seated before proceeding. Lightly lubricate all caliper sliding surfaces with lithium-based grease. Install the outboard pad on the caliper bracket and then install the caliper. Attach the flexible brake hose and rigid brake hose, tightening the flare nut. Finally, bleed the system.
