Removing ( Refitting ) Position the vehicle on the ramp.Proceed with removal  - 5530B10  battery - r+r .

When removing the battery, make sure also to disconnect the starter motor supply lead, shown in the figure, from the maxi fuse box.

Proceed with removal  - 4450B02  left front wheel r r . Remove the protective cap on the brake caliper bleed valve. Connect the collection system (pipe and reservoir) to the bleed valve on the brake caliper. Operate the brake pedal until the brake-clutch fluid reservoir is empty. 1. Disconnect the electrical connection from the A.B.S. hydraulic and electronic control unit.
