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.
CAUTIONBleeding of four-wheel antilock brake systems require the use of a dedicated scan tool. Lines should not be disconnected unless one is available.
- Pry the piston side pad away from the rotor with a tool that won't scratch the rotor surface.
- Remove the caliper bolts or pins.
Remove the caliper from the rotor.
NOTEDo not apply the brake pedal with the caliper off the rotor. Use a soft wedge (such as a piece of wood) to hold the pads apart if the caliper is to be off the rotor for any length of time.
- 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.
Install and tighten the caliper slide pins to 22 ft. lbs. (30 Nm).
NOTEStart the bolts or pins by hand before tightening to avoid crossthreading.
- Connect the brake line using new washers.
Bleed the caliper.
CAUTIONBleeding of four-wheel antilock brake systems require the use of a dedicated scan tool.
- 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.
- Before servicing the vehicle, please familiarize yourself with safety procedures.
- Raise and support the front end on jackstands.
- Remove the wheels.
- Disconnect the rubber brake hose from the tubing at the frame mount. If the pistons are to be removed from the caliper, leave the brake hose connected to the caliper. Check the rubber hose for cracks or chafed spots.
- Plug the brake line to prevent loss of fluid.
- Remove the caliper slide pins.
- Remove the caliper and brake pads from the rotor adapter.
- Position the outboard shoe in the caliper. The shoe should not rattle in the caliper. If it does, or if any movement is obvious, bend the shoe tabs over the caliper to tighten the fit.
- Slide the caliper into position on the adapter and over the rotor.
- Align the caliper and start the pins in by hand.
- Tighten the pins to 22 ft. lbs. (30 Nm).
- Connect the brake hose to the caliper. Use new washers to attach the hose fitting if the original washers are scored, worn or damaged.
- Fill and bleed the brake system.
- Install the wheels.
Lower the vehicle.
Before servicing the vehicle, please familiarize yourself with safety procedures.
CAUTIONNever allow the disc brake caliper to hang from the brake hose. Damage to the brake hose with result. Provide a suitable support to hang the caliper securely.
- Raise and support the vehicle.
- Remove the tire and wheel assembly.
- Compress the disc brake caliper.
- Remove the banjo bolt and discard the copper washers.
- Remove the caliper slide pin bolts.
- Remove the disc brake caliper from the caliper adapter.
Remove the caliper slide pins from the adapter.
- Thoroughly coat the new slide pins on all working surfaces.
- Install the boot onto the slide pin and then insert into the adapter.
Push the pin all the way into the adapter and carefully expel the trapped air by gently pushing on the boot near the slide pin head.
NOTEInstall a new copper washers on the banjo bolt when installing
- Install the disc brake caliper to the brake caliper adapter.
- Install the banjo bolt with new copper washers to the caliper. Tighten to 28 Nm (250 inch lbs.)
- Install the caliper slide pin bolts. Tighten to 32 Nm (24 ft. lbs.).
- Bleed the base brake system.
- Install the tire and wheel assembly.
- Lower the vehicle.
