There is a block in the rear line just before the rear t, waiting for parts to be here... So I was thinking its blocked... Would the rears affect the fronts, I thought that I would have plenty of braking even without rears...

i pulled the pads and they looked to be glazed over and the rotors were very shinnny...... I rubbed the pads with sandpaper and got a new surface and scuffed up the rotors a little...

I'm just confused because when I had just one front drum working, if I stood on it hard enough it would lock up..... I was wondering if the proportioning valve is getting in the way and I need to just bypass it, Keep the rears running through it.... ( as you can tell I am a novice so help would be great)

Also the master is from the el camino is a disc/drum.... wouild it not be strong enough without booster? Do I need to go with a 73-87 disc/drum no booster? Don't want a booster if I dont have to... Ma$be down the road.... Thanks again
