driver must sit in the seat and the steering /
park brake controls must be moved into the

Park Brake

Visually check that no damage is found on the
steering control levers, links or switches belonging

Tighten the pivot nut until the braking action is
correct. Replace the steering boot, making sure
the boot top sits between the two adjustment bolts
on the steering control.
