REDUCING BRAKE PEDAL EFFORT ON FIREBIRDS WITH FOUR WHEEL DISC BRAKES - ALL 1982-84
The higher brake pedal effort associated with 1982-84 Firebird vehicles equipped with four wheel disc brakes may be a source of some customer
comments. The J65 brake system was designed with a low pedal ratio for reduced free travel and a firmer and higher effort pedal for the high
performance buyer. Owners of J65 equipped Firebird vehicles not sharing this interest and desiring reduced brake pedal effort can be accommodated by
replacing the original production master cylinder assembly with the appropriate J50 master cylinder unit specified below.
