2 Place a suitable container beneath the valve to catch spilt fluid, then unscrew the union nuts and disconnect the fluid pipes.

Plug the open ends of the pipes and valve to prevent fluid leakage and dirt ingress. If fluid is accidentally spilt on the paintwork, wash off immediately with cold water.

3 On early models, the valve is secured to the mounting bracket on the inner wing by a single bolt. Unscrew the bolt and remove the valve.

4 On later models, the valve is secured to the mounting bracket by a clip. Remove the clip and slide out the valve.

Refitting
5 Refitting is a reversal of removal, but note that the early type of valve must be fitted with the cover bolts facing forwards, and the later type of valve must be fitted with the smaller diameter stepped end facing forwards.

6 On completion, bleed the rear hydraulic circuit.
