A truck like the Dodge Durango is often driven hard, and that takes a toll on the brakes. Eventually, parts like the calipers will need to be replaced. If you're a truck driver looking to replace your Durango's calipers yourself, study up on the procedure and consult with your mechanic before doing so.
Raise and support the truck. Place a prop rod on the brake pedal to keep pressure on the system. Remove the tire and wheel from the vehicle.
Disconnect the banjo bolt that supports the brake hose to the caliper. Toss away the copper washers. Plug the brake line with a piece of rubber.
Remove the slide pin bolts. You can then remove the disc brake caliper from the adapter.
Install the new disc brake caliper on the caliper adapter.
Connect the banjo bolt onto the caliper, using new copper washers. Make sure the brake hose isn't twisted or kinked. Tighten the bolt to 21 foot pounds.
Attach the caliper slide pin bolts. Tighten them to 24 foot pounds.
Remove the prop rod from the pedal. Bleed the brake system of any loose air by opening the bleeder valve and manually holding down on the pedal.
Install the tire and wheel assembly then lower the vehicle.
