1972 El Camino


I have to ask, what master cylinder do I need with stock front discs, and s-10 rear discs. I want to keep the booster I have now. It looks like I need a booster with a 1 1/16 inch bore. And those look to come from the 68 corvettes. I just want to ask before I bought one.

Next, what about prop valves. Could I use the one of the blazer I pulled the discs off of, or do I need to try to find something different.

Thanks for the replies.

I see you read posts...have you read mine from last year?

It's been awhile since I did research, but my memory says it's a 1 1/8" Corvette MC you're after for 4-wheel discs (see the links for the pushrods...you're gonna need that info). If you want to keep the brake warning light (pressure), you still need an adjustable prop valve (Wilwood, after the oe valve) as every vehicle is different for bias. If you don't care about the warning light, all you need is a T-block for the fronts, and the adj prop valve for the rears.

Go here for pressure info on MC's...go to the beginning of the article if you want the whole shebang.

My link at top has several more links on MC's. Booster is a whole other question. If I recall, there is a 'manual' 4-wheel disc MC available for the Corvette as well, eliminating the need for a booster (pressures dictate). If you need a 'new' booster, there are several available, though I'm going with ABS's electric/hydraulic setup eventually (see May 2004 'Classic Trucks' issue, page 86, 'Small Space, Big Reward').

If I'm remembering anything incorrect here, I apologize. I diligently researched my info on the top link, and the answers are there...if not here.

I stand corrected if anybody disagrees.

I never found your old post. Thanks for the info. I do believe that I've found the one I need for power discs off of a 68 vette. The part number is Tru Torque M89160 at advance auto parts. I'll post back when i go check it out. Thanks so much for the help, and I'll definantly be posting back.

I got the mc yesterday and it is for a deep hole application. I can put up pics on my website if anyone needs them.
