2. Install a clamp on the brake pipe that goes to the brake caliper. Alternatively, you can remove the filler cap of the brake fluid reservoir and seal the filler hole with polyethylene. This will reduce fluid loss during the next procedure.
3. Loosen the hydraulic hose connection, but do not unscrew it at this stage (photo).
4. Follow the procedure for removing the brake pads given in Chapter 10.
5. On the Girling caliper, remove the handbrake cable retaining spring clip.
6. Turn the handbrake control lever, disconnect the inner cable and remove the cable housing from the caliper.
7. Unscrew the hydraulic hose from the caliper. Plug the end of the hose.
8. If necessary, unscrew the caliper suspension frame on the rear axle.
9. Installation is carried out in the reverse order, making sure that all mating surfaces are clean and tightening the bolts and connections to the tightening torques specified in the Specification. Finally, bleed the hydraulic system as described in Chapter 17. If the fluid loss was minimal, it will be enough to bleed only one caliper.
