Brakes - High Pedal Effort

Group Ref.: Brakes
Bulletin No.: 335010
Date: December, 1993

SUBJECT:
HIGH BRAKE PEDAL EFFORT (REPLACE PADS WITH NEW LINING MATERIAL)

MODELS:
1992-93 CHEVROLET CAVALIER
1992-93 CHEVROLET CORSICA AND BERETTA

Condition:

Some owners may comment about high brake pedal effort.

Correction:

A reduction in brake pedal effort can be accomplished by replacing the original pads with new lining material, P/N 18021949.

Owners should be advised that some brake squeal may be associated with the new lining material, particularly in warm weather and periods of heavy brake usage. The new lining is used to address owner comments about high pedal effort ONLY and not as a general service lining replacement. DO NOT refinish the rotors when installing the new pads.

DO NOT TURN ROTORS FOR THE FOLLOWING:
pad replacement, brake noise, pedal effort/feel.

Rotors should only be turned for: pulsation concerns, heavy scoring - in excess of .060" (1.5 mm). If the front rotors on a high-pedal-effort vehicle have been previously turned, they should be replaced. Light surface rust on rotor faces will not affect brake performance.

Parts are currently available from GMSPO.
