Where is the best place to get anew booster and proportioning valve? This is for my 70 C20 3/4 ton

You can get an unloaded booster from NAPA. That's where I got mine.

For my 1970 3/4 2500 I bought one from www.brakeboosters.com

I forget where I got the prop valve, but I know they're not cheap (like $250 from memory).

70s had 4 wheel drum brakes. Has yours been converted to front discs, or is it still original? The hardware you are asking about is different disc vs. drum.

^^ What he said. There was no proportioning valve with your drum/drum system, it came with a distribution block. Similar appearance but different inside.....

Correct, mine is drum drum, so I need the distribution block. Do you know where to get that at?

I thought they also sold the bracket, but I don't see it on their website. Might be worth a call though. Those they have for the cars don't look right.

I should point out, as other's have noticed, that mine is a '72 front disc conversion, it also had drums and no prop valve originally. Sorry, I completely forgot it wasn't original to my truck!

What are you suggesting, that he rebuild his own booster? Just opening one requires an arbor press and courage.... and it's not the safest thing in the world either, there's a ton of potential energy in there. Enough that it can fly all the way across your shop and hit your Camaro.

WarMonger · 10-20-2016, 06:20 PM

another brake question. Is there a difference in the lines ( like dia) between a 1/2 ton and 3/4 ton? Or do they all use the same size lines?

Did you check the link? www.piratejack.com

That's not what he is suggesting at all...

I don't own any Camaros , I had a few and moved up to classic Corvettes , Who said anything about rebuilding anything ?
