3 Working inside the vehicle, remove the spring clip which attaches the pushrod to the arm of the brake pedal.

4 Unscrew the nuts which hold the servo to its mounting bracket, also the servo support brace to the body.

5 Disconnect the valve hose from the servo.

6 Detach the linkage arm spring at the rear of the servo and then pull the servo forward until the servo operating rod can be unclipped from the linkage.

7 Remove the servo from the vehicle. It must be renewed if defective, no repair is possible.

8 If necessary, the rest of the servo operating linkage can be removed from under the instrument panel once the covering and cowl side trim have been removed from above the brake pedal inside the vehicle. Unbolt the connecting link bracket from the drivers side (see illustrations).
