Wheel removal. Remove the wheel and loosen the lug nuts with the ratchet. Remove the wheel and the nuts, and set them aside.
Caliper removal. Loosen the banjo bolt that links the brake caliper to the brake line. Loosen and remove the bolts that keep the caliper attached to the wheel assembly. Don’t forget to place a drain pan under the brake mechanism to catch the brake fluid. Remove the bolts, rubber boots, and sliders from the caliper and lubricate all of these mounting components.
Securing the new caliper. Compress the piston of the new caliper with the brake caliper piston tool. Attach it to the end of the brake line. Lubricate the caliper bolts, put the new brake pads on it, and secure it to the wheel assembly. Finish the job by attaching the brake hose and tightening the banjo bolt.
Bleeding the brakes. Fill the master cylinder and connect a hose to the bleeder valve. Now, open the valve and ask someone else to press down on the brakes at that time. Close the valve when you see air bubbles in the jar. Repeat this process until there’s no bubble left in the jar. Refill the cylinder and close the bleeder valve.
Securing the wheel. Use your hands to tighten the lug nuts after putting the tire back on the wheel assembly. Once you put the car on the ground by taking off the jack, tighten the nuts with the ratchet.
Congratulations! You’ve just got rid of your brake caliper sticking problem!
