If your using the stock B body master cylinder and it was for drum brakes for both front and rear then you need to remove the residual valve from the line that the front brakes are hook up to, which is normally the rear line and reservoir If it is the stock drum brake master cyliner remove the brake line and get a small # 6 or #8 sheet metal screw around one inch long and thread it into the brass insert inside that port, once it is theaded in two or three turns pry it out. The residual valve is behind the brass retainer, it looks like a rubber flapper valve with a small spring in it, remove it and reinstall the retainer and hook the brake line back up, make sure and tighten it real tight so the seal on the retainer will reseal in the master cylinder and on the brake line, bleed the brakes and let us know if that was the main problem or not

Cab, what about on 73-76 A-body disc brakes? I've got the later 2 bolt M/C and my fronts are tight too.
I've also heard of racers adding springs between the brake pads to help eliminate drag on the rotors?
opinions?

if it was a race only car i would ( if i wasn't out of a job right now) but i heard that it takes a few pumps on the pedal till they stop the car( which is probably why they have ZERO resistance ) and this is basically my daily driver when there isn't 2 frikkin' feet of snow on the ground . seriously though aerospace look like a really nice setup
You heard wrong on the pumps to stop the car. The first pump is softer as it is setting the piston but will stop the car just fine. I can nose dive my Demon at the stripe running 144 mph. The second pump brings the pressure to max (1100psi) and is very firm.
BTW - Aerospace makes a street kit as well that has no resistance.
Sorry about the job and the snow.

demon, is there a link for aerospace just to see the street kit, even if i don't buy now. 68fastback thanks for that link, interesting, i was thinking about a spring to separate the pads and all around informative bit of info. thx very much guys for informing me
do you have PIN type calipers ??? I think you'll need those to do the spring trick if I am reading the link above correctly , you'll need a pretty hefty spring to get a sliding caliper to move .

What keeps the coil spring on the pin from pushing the piston too far back??
I'm sorta thinking that you could get that scary feeling that you get when you forget to pump the pedal on the daily driver after a pad swap but at 120mph.....

If the caliper's are hanging up any they will drag, I fixed mine a few years ago by putting new caliper's on it,,,,and yes Monte's Idea work's, but the ultimate answer is Aerospace.

When I think of it, I turn the wheel back and forth a quarter turn, but its a stick car. It does work though
