Jan 16, 1979

THE FRONT HOSES ON THE INVOLVED VEHICLES MAY HAVE IMPROPERLY ORIENTED HOSE FITTINGS, RESULTING IN A RUBBING CONTACT BETWEEN THE RIGHT BRAKE HOSE AND THE UPPER CONTROL ARM OF THE FRONT SUSPENSION OR IN A TWISTED LEFT HOSE RESULTING IN A FAULTY ATTACHMENT AT THE FRAME FITTING. SHOULD EITHER OF THESE CONDITIONS EXIST, THEY COULD EVENTUALLY RESULT IN BRAKE HOSE FAILURE CAUSING LOSS OF BRAKE FLUID AND CONSEQUENT LOSS OF THE FRONT BRAKING ACTION.

Consequence & remedy

Consequence: Not supplied

Remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, REPLACE ONE OR BOTH FRONT BRAKE HOSES AT NO COST TO OWNER.
