Removal
CAUTION:Bleeding the ABS is not a routine maintenance operation and should only be necessary when part of the system has been disconnected or the fluid is contaminated.
During the bleed procedure, it is important that the level of fluid in the reservoir is maintained at approximately 2 mm below the bottom of the filler neck.
Do not allow the pump motor to run continuously for more than two minutes. If, for any reason the motor does overrun the two minute time limit, switch the ignition OFF and allow the motor to cool for at least ten minutes before continuing with the bleed procedure.
1. Discharge the hydraulic accumulator by operating the brake pedal until the pedal goes hard (approximately 20 times).
2. Place suitable absorbent material around the reservoir area to catch any spilled fluid.
Removal
1. Remove one wheel nut, mark the wheel relative to the stud, and remove the remaining wheel nuts. Remove the road wheel and tire assembly.
2. Carefully remove the caliper retaining spring (1). Remove the pad wear sensor multi-plug from the retaining clip, then disconnect the harness multi-plug (2).
3. Loosen the caliper feed pipe union nut. Remove the caliper securing bolt dust caps then remove the socket head securing bolts (3). Remove the caliper from the carrier
4. Remove the brake pads (4),
5. Fully unscrew and remove the caliper from the brake hose. Install a suitable plug to the brake caliper hose to prevent loss of fluid and the ingress of dirt. Use of a Hose Clamp will help reduce the loss of fluid.
6. Clean and examine the brake pads.
WARNING: Brake lining dust can contain asbestos which if inhaled, can damage your health. always use a vacuum brush to remove dry brake lining dust. never use an air line.
Installation
1. Place the caliper to the front of the carrier then remove the plugs from the caliper and hose.
2. Install but do not fully tighten the caliper feed hose. Remove the hose clamp.
3. Ensure the caliper piston is fully retracted then fit the brake pads to the caliper.
NOTE: If the pads are worn to the minimum thickness, new pads must be fitted.
4. Reposition the caliper/pad assembly to the carrier then install and tighten the caliper securing bolts to 131-175 Nm (97-129 ft lb).
5. Install and fully seat the dust covers.
6. Final tighten the feed hose union nut to 7-12 Nm (5-8.8 ft lb).
7. Install and fully seat the caliper retaining spring. Connect the brake pad sensor harness multi-plug then reposition the plug into the retaining clip. Ensure that the harness cannot foul or chafe.
8. Install the road wheel.
9. Bleed the brakes. Service and Repair
