CHAPTER 2 MAINTENANCE

1.14 BRAKE PEDAL ADJUSTMENT
1. Early models may have a stop bolt to adjust pedal free play. The stop bolt was
eliminated on new production. Brake pedal free play adjustment is not required.
The plunger will not pull out of the booster. It is recommended that if you have
a stop bolt, it be removed. However, if you have excessive free travel, it may be
caused by worn brake linings, pads, or both.
2. It is not acceptable for the brake pedal arm to return and hit against the spring
bracket. It must clear the bracket by 1/4” .
3. If the brake pedal hits the spring bracket, remove cover plate from lower edge
of dash. Loosen the 1/2-20 jam nut on master cylinder push rod.
4. Thread push rod into connector to increase pedal clearance. Thread it out of
connector to decrease pedal clearance.
5. Retighten the 1/2-20 jam nut. Replace cover plate.
