1955 Packard- weak brakes

Posted by Michael C Wauhop On 2011/9/26 14:09:53

Well I rebuilt the treadle-vac, fabricated some new lines, bled the brakes and still-TOO WEAK. after I bled the breaks the pedal was nice and hard but the minute I fired up the engine-my pedal went down to the floor. The brakes were able to stop the car while I took a test drive around my street but way too weak too take it anywhere of any distance. Does anyone have a suggestion as to how to solve my problem? (and yes I am considering replacing the treadle vac with something else).
