Hi, I am having a 1956 Ford F100 done--They took a 1977 el camino and are using most parts from it. Motor (350) transmission,rear end ,power steering, elec.etc,etc. The truck has a sub frame 1977 Plymouth. Has new disc brakes. (plymouth) rear are drums from el camino. They have put (3)master cylinders on it,bled the brakes --power bled-- the booster has a lot of suction. All brake parts are new. When the brakes are pumped a couple of times there are brakes --after it sets for a minute --no brakes. We can.t figure out what is wrong!! Any help would be appreciated. Just found this site today. Thanking you in advance. Vince 330-542-3010

I can't help you with the brakes. I know nothing about anything chevy related. I do know a little about the 56 ford f-100 though.

Mine is bone stock for now. Check out my journal (just starting).

Post up some pics of yours and what you are having done to it.

I plan on doing every part of mine myself, but it will just be a driver and not a show truck. I know it won't be show quality.

Matt, Don't have pictures yet. Will post as soon as I have them. Thanks, Vince

when I re read the post, it seally sounds like you got air in the system. don't bleed the brakes with the car running for any reason, bleeding it with the brake booster working makes tiny air bubbles that cannot get out without letting the car sit. crack the frt bleeders open, and gravity bleed them ( let the bleeders stay open, do not pump pedal for any reason ), fill the master and leave it for an hour or so, close frts, jack up front, and open rears, and do the same, see if this cures it.

check to see if your frt calipers are on the wrong sides, check them, if the bleeders are not facing up, switch calipers around to the other side and gravity bleed frts, and you should have a pedal.

Is the pedal firm when it does come up? if so, it sounds like the fluid is draining back to the mc. if the master cylinder is under the floor you will need to put some residual pressure valves in the lines. The master cylinder, if it is the elcamino might already have a 10# rpv in the rear brake port. If you used an aftermarket booster/mc combo it probably has no rpv in the mc. put a 2# in the front line and a 10# in the rear. it won't hurt to have 2 rpv's in the line as they are not cumulative. Hope this helps, mikey
