hi al ,wondering ,can I use a universal one that edlebrook has listed .for a 65 starefire? have changed wheel cylinders power booster and master cylinder, a few times feels like im stepping on a brick, just slows down alittle , thanks for ant help/ will

 

Four wheel drum cars do NOT use a proportioning valve.

 

down on the frame below the booster there is a brass type union , which I thought was the valve, well I guess that ends that ray of hope.thank you for the info. will

 

That is simply a distribution block. There is no valve inside of it. What master, booster, and wheel cylinders? Stock replacement or something else? What is the vacuum level at the booster?

 

thanks , all stock, vacuum is 17 to 18 lbs, sometimes brackes will work good if put neutral when im coming to a stop.2 new masters and 2 new boosters, thanks again , will

 

Obviously if the brakes don't work consistently, you have a problem. If the pedal is hard, that's a booster problem. Could be that the pushrod isn't adjusted properly, or it could be that the air admittance valve sticks sometimes.

 

just seems odd that two would be messed up ,I will check into the booster push rod being in the wrong hole ,thanks for the patience and the advice.will

 

I'm hedging towards push rod adjustment. It isn't a necessarily a case of the wrong hole, even w/ the correct hole, the push rod between the MC and the brake booster needs correct travel distance (adjustment).
