REMOVAL & INSTALLATION
- Raise and support the vehicle.
- Remove the wheel.
- Disconnect the brake line from the caliper if the unit is to be removed from the vehicle. Plug the end of the brake line. Be sure to use new washers on installation. Disconnecting the line will require bleeding of the system.
- Pry the piston side pad away from the rotor with a tool which won't scratch the rotor surface.
- Remove the caliper bolts or pins.
- Remove the caliper from the rotor.
- Clean the caliper slide surfaces with a wire brush where applicable. Then lubricate the surfaces with a thin coat of high temperature grease.
- Push the piston(s) in far enough to allow the pads to clear the rotor. This can be done by hand or with a special tool: several types are available.
- Install the caliper on the rotor.
- Dakota, Durango: install and tighten the caliper slide pins to 22 ft. lbs. (30 Nm).
- Ram: tighten the caliper bolts to 38 ft. lbs. (51 Nm) on 1997-99 models; tighten to 24 ft. lbs. (33 Nm) on 2000 models.
- Connect the brake line using new washers.
- Bleed the caliper.
- Install the wheel.
- Apply the brake several times to seat the pads before operating the vehicle.
- Check the brake fluid level at the master cylinder reservoir and add if necessary.
- Remove the caliper from the vehicle and place on a clean workbench.
The first method is as follows:
- Stuff a shop towel or a block of wood into the caliper to catch the piston.
- Remove the caliper piston using compressed air applied into the caliper inlet hole. Keep pressure low! It doesn't take more than a few psi in a short burst to move the piston!
- Inspect the piston for scoring, nicks, corrosion and/or worn or damaged chrome plating. The piston must be replaced if any of these conditions are found.
- If equipped, remove the anti-rattle clip.
- Use a prytool to remove the caliper boot, being careful not to scratch the housing bore.
- Remove the piston seals from the groove in the caliper bore.
- Carefully loosen the brake bleeder valve cap and valve from the caliper housing.
- Inspect the caliper bores, pistons and mounting threads for scoring or excessive wear.
- Use crocus cloth to polish out light corrosion from the piston and bore.
- Clean all parts with denatured alcohol and dry with compressed air.
- Lubricate and install the bleeder valve and cap.
- Install the new seals into the caliper bore grooves, making sure they are not twisted.
- Lubricate the piston bore.
- Install the pistons and boots into the bores of the calipers and push to the bottom of the bores.
- Use a suitable driving tool to seat the boots in the housing.
- Install the caliper in the vehicle.
- Properly bleed the brake system.
- Install the wheel, then carefully lower the vehicle
