Hi. New to the boards, new to owning a Packard. Ours is a 39 business coupe. When I got it, the brake pedal was to the floor. Got a m/c rebuild kit, installed it, but when I push down the brake pedal, the fluid comes out a small relief hole in the cap. If someone can give me some advice I'd sure appreciate it. /Thanks/Butch
Butch, Do the brakes work now (fluid expnading shoes etc.) or does the pedal still go to the floor? I am wondering if the relief valve was installed correctly or thee is not enough free play in the pedal to piston actuation (It should be about 1/2" ) ?
I'm guessing the answer is that when you reinstalled the master cylinder, you didn't you didn't make the pedal free play adjustment, or didn't go far enough. Adjust the turnbuckle to allow for 3/4" pedal free play, otherwise the MC piston may never returns to it's proper "rest" position and the port between the reservoir and the cylinder isn't closed off.
