1965 Valiant low brake pressure

Ok, i would recommend a dual, split line system upgrade. Safer and works ALOT better. Did it on a '64 Chevy pick up and was surprised in the difference it made. And not too hard to do.

Until then:
Next I would check that you have enough freeplay in your pedal. If your pedal doesnt come back enough to clear the ports inside your MC you'll never create pressure. And check the pedal rod that goes into the MC. I once had a replacement MC that had a shorter length hole than the original and I had to cut down the brake rod.

Thats is one problem ive been having, it doesnt come all the way back and Ive had to keep adjusting the brake light switch so the lights turn off, so if I rig a spring or something in there to pull the pedal all the way up would it fix the probem at all? I know its supposed to return by pressure, but its not doing that. Or would just pulling the pedal all the way up and pumping a few times fix the problem? I also held the two MC's nect to eachother and made sure everything was the same size, so the shaft isnt the issue.
