So I got my 66 Coronet on the road that I've been working on for a couple years.
Someone had installed an SSBC Front Disc Brake conversion kit. Nothing looked to be wrong with them, looked like they had hardly ever been used when I got the car.
I rebuilt and replaced all the parts on the rear drum brakes, as well as the master cylinder, as the old one had rust in it.
Flushed the system, power bled it; made sure the rears were adjusted correctly.
The car stops terribly. I smashed the brakes as if in a panic stop, couldn't get any of the wheels to lock up. The pedal is hard. Feels like you better plan your stops and hope nothing jumps out in front of you unexpectedly.
It doesn't pull or anything, it just doesn't seem to have the stopping power it should have, especially with the SSBC 4 piston calipers.
Rears seem to be working fine, proportioning valve is set all the way open, and they were good and warm when I got back to the shop after a 5~ mile test drive slamming on the brakes several times. Doesn't make a difference if I adjust the proportioning valve at all.
They are manual brakes.
Any suggestions? I am thinking maybe the disc kit that is on the car is not enough.
