I have a very hard brake pedal at idle on my '69 Coronet, I think the power brake booster needs rebuilding.




You can check the booster function -

1) With the engine off, pump the brake pedal about 10 times.

2) With your foot applying light pressure on the brake pedal, start the motor and you should feel the pedal drop a bit.




Darnit!!
Its already apart!!!
