REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Remove as much brake fluid as possible from the master cylinder reservoir.
- Raise and support the vehicle safely on jackstands. Remove the front wheels.
- Use a C-clamp to compress the piston into the caliper bore.
If your vehicle is equipped with rear parking brakes, compress the piston only slightly.
- Release the parking brake and disconnect the cable from the caliper lever, if equipped.
- Remove the brake hose from the caliper body and plug the hose to prevent the entrance of dirt or moisture.
- Remove the caliper bracket retainer bolts.
- Slide the caliper and bracket assembly off the spindle and rotor.
- Remove the brake pads, backing plates and retainer clips.
- Compress the piston assembly into the cylinder bore.
If equipped with parking brake, use a suitable tool to rotate the piston back into the caliper bore.To install:
- Install the caliper bracket to the spindle assembly, and secure in place with the retainer bolts. Tighten the retainer bolts to 16--23 ft.lbs. (22-31 Nm) for all models except Legacy, Impreza and SVX. For Legacy, Impreza and SVX, tighten the retainer bolts to 12-17 ft. lbs. (16-22 Nm).
- Install the pad retainer clips, brake pads, backing plates and caliper.
- Install the hand brake cable, if equipped.
- Connect the brake hose using new sealing washers, and tighten the fitting to 12-14 ft. lbs. (16-20 Nm).
- Bleed the brake system. Install the wheels and lower the vehicle. Check the fluid level in the master cylinder.
See Figures 5, 6, 7, 8 and 9
- Remove the brake caliper from the vehicle and place on a clean work surface.
- Remove the inlet fitting from the brake caliper and drain all brake fluid.
- Place a piece of wood in the caliper opening. Use a small amount of compressed air and force the piston from the bore.
- Remove the piston boot retainer ring, if equipped. Remove the piston boot and seal. A pick tool can be used to extract the seal from the caliper bore. Be careful not to scratch the bore while removing the pieces.
- Inspect the piston and the caliper bore for damage or corrosion. Replace the caliper and/or the piston if necessary.
- Remove the bleeder screw and rubber cap if equipped.
- Clean all of the parts with non-mineral based solvent and blow dry with compressed air. All rubber parts should be replaced.
- Inspect the guide pins for corrosion, replace if necessary. When installing the guide pins, coat them with a silicone lubricant.
- Lubricate the piston, caliper and seal with clean brake fluid.
- Install the seal into the caliper bore making sure it is not twisted in the bore groove.
- Install the boot onto the piston, then position the piston into the caliper bore.
- If the caliper is equipped with the parking brake, then use a suitable tool to rotate the piston back into the caliper bore.
- If not equipped with a parking brake, bottom the piston into the bore using your hand and a piece of wood to compress the piston.
- Install the bleeder valve and tighten to 6-7 ft. lbs. (8-9 Nm).
- Install the caliper to the vehicle and properly bleed the hydraulic brake system.
