Subject: BRAKE PULSATIONS


Model and Year: 1980-85 CITATION 1982-88 CAVALIER, CELEBRITY 1987-88 BERETTA, CORSICA
TO: ALL CHEVROLET DEALERS


Chevrolet Dealer service Bulletin 88-356-5 dated November, 1988, is being reissued to expand model application. All copies of the November bulletin should be discarded.

Some of the subject vehicles may experience a shudder or pulsation vibration when the service brake is applied. This is commonly referred to as "Brake Pulsation", and generally results from uneven wear of the brake rotors. Uneven rotor wear could be caused by high lateral slide forces of the brake calipers.

The caliper slide force may be reduced by replacing the current slide pins with new reduced diameter pins.

Whenever the caliper mounting bolts are serviced, the caliper mount bolt holes must be thoroughly cleaned and the area between the mount bolt bushings packed with silicone grease, PIN 12345579 or equivalent.
