NUMBER: 06-30-01RDATE: 03/06/02
APPLICABILITY:
2001 2002MY Legacy Vehicles with 16-inch Brake System
SUBJECT:
Brake Squeal Noise
INTRODUCTION
This updated bulletin is to inform of a change in production to eliminate brake squeal noise in addition to the previous bulletin dealing with a field repair procedure (the installation of brake shims)
PRODUCTION LINE CHANGE
1) 16-inch front disc brake caliper, housing bracket, and pad kit have been changed to eliminate the brake squeal in reverse, that occurs after a cold soak.
2) The applicable VIN numbers have incorporated the changes:
FRONT HOUSING CHANGED (EFFECTIVE AUGUST 8, 2001 BEGINNING WITH THE FOLLOWING VINS)
FRONT CALIPER AND PAD KIT CHANGED (EFFECTIVE OCTOBER 12, 2001 BEGINNING WITH THE FOLLOWING VINS)
Any VIN # after this change should not have the Brake Squeal concern or require the brake shim modification.
PART NUMBERS: NEW AND OLD
FIELD PROCEDURE:
For vehicles produced prior to the previously outlined production line change, if the customer complains of a brake squeal in the AM when backing up on the first application, you will need to install a new style brake shim part # 26298AE020. This part number will include a set of four (4) shims.
Note:
If you are replacing a pad kit for maintenance, you will need to install this shim set.
INSTALLATION PROCEDURE:
1) Remove the front wheels.
2) Loosen the front upper caliper bolt. Remove the lower bolt and swing the caliper up out of the way.
3) Remove the inner and outer brake pads, making sure not to mix the two pads.
4) Remove the OEM shims from the pads and DISCARD.
5) Spray brake clean on a shop towel and clean the grease from the back sides of the brake pads. Make sure that the slit on the front side of the brake pad is clean.
6) Inspect BOTH SIDES OF the brake rotors at this time. If they are grooved, scored, or discolored, they should be resurfaced before proceeding to the next step.
7) Compress the caliper pistons at this time. Clean the inner sides of the caliper with brake cleaner. This will allow the shims to adhere.
8) Remove the blue plastic film from the inner side of the new shim and adhere it to the brake pads. DO NOT REMOVE THE BLUE FILM FROM THE OUTSIDE OF THE SHIM AT THIS TIME.
9) Install the brake pads back into the pad holders, making sure to grease the ends of the brake pads (slotted ends).
10) Remove the blue film from the outside of the shims and swing the caliper back into position.
11) Install the lower bolt and tighten both bolts, torque the bolts to 29 ft lbs. Reinstall the wheels and start the engine. Depress the brake pedal 5 times to make sure the glue on the shims is secured firmly.
