CORRECTION:

1. CHECK/ADJUST BRAKE AND CRUISE CONTROL SWITCHES. PULL UP FIRMLY ON THE BRAKE PEDAL. IF CLICKS ARE HEARD FROM THE SWITCHES SLIDING IN THE RETAINERS, THE BRAKE SWITCHES WERE PROBABLY OUT OF ADJUSTMENT.

IMPORTANT:

AFTER MAKING THIS ADJUSTMENT, ALWAYS CHECK TO MAKE SURE THE SWITCHES ARE STILL HELD SECURELY IN THE RETAINERS. ALSO, CHECK FOR PROPER OPERATION OF THE CHMSL (CENTER HIGH MOUNTED STOP LAMP) AND THE BTSI (BRAKE TRANSMISSION SHIFT INTERLOCK.)

2. IF THE SOUND INSULATOR IS INTERFERING WITH THE BRAKE PEDAL, REPOSITION AS FAR BACK AS POSSIBLE. WHEN INSTALLING THE SOUND INSULATOR, BE SURE IT IS POSITIONED ON THE REAR LOCATING STUD. IF DOES NOT PROVIDE SUFFICIENT CLEARANCE, TRIM THE SOUND INSULATOR IN THE AREA OF THE BRAKE PEDAL UNTIL YOU HAVE APPROXIMATELY 12 MM (0.5 IN.) CLEARANCE.

3. IF THE BRAKES HAVE BEEN DRAGGING, CHECK RELATED BRAKE PARTS FOR HEAT DAMAGE. CHECK SEALS ON CALIPERS, WHEEL CYLINDERS, AND BEARINGS. ALSO CHECK BRAKE LININGS AND SHOES FOR CRACKS AND/OR CRUMBLING ON THE SURFACE. DISCOLORATION OF THE ROTORS AND/OR DRUMS DOES NOT DAMAGE THEM. CHECK THE BRAKING SURFACES FOR CRACKS.
