  Q: How to replace a caliper due to fluid leaks, a stuck piston, or a broken bleeder screw?

  A: If Brake Caliper replacement is necessary due to fluid leaks, a stuck piston, or a broken bleeder screw, it is important to consider your options. New and factory rebuilt calipers are available on an exchange basis. To begin the replacement process, loosen the front wheel lug nuts and raise the front of the vehicle, securely supporting it on jackstands. Apply the parking brake and remove the wheels. Next, remove about two-thirds of the fluid from the master cylinder reservoir and discard it. Position a drain pan under the brake assembly and clean the caliper and surrounding area with brake system cleaner. On 2WD pick-up models, use a C-clamp to push the piston back into the bore, creating clearance for the new brake pads. Be cautious of the rising fluid in the master cylinder and siphon off any excess if necessary. For 2WD pick-up models, remove the banjo bolt and discard the sealing washers. Plug the banjo fitting with a piece of rubber hose to prevent brake fluid from dripping out and contaminants from entering the system. On 4WD pick-ups and all 4Runner models, unscrew the tube nut fitting and detach the Brake Line from the caliper. Remove the caliper mounting bolts and, if necessary, remove the brake pads. If reusing the same caliper, clean it with brake system cleaner and inspect for leaks or damage. Install the caliper and tighten the pins or bolts. Connect the brake hose to the caliper using new sealing washers and tighten the banjo bolt or brake line fitting securely. Bleed the front brake circuit if necessary and check brake operation before placing the vehicle into service.
