what master cylinder will work?

[jknox67]

I'll jump right into it! I have a 67 camaro which I converted to four wheels disc brakes. Willwoods in the front and a no name brand in the rear. I need to know what I can use for a master cylinder setup? Can I just use a stock power disc setup even though its for front disc / rear drum? Or do I have to search out a 2000 camaro or corvette setup? I talked to a few to many people and got way to many awnsers.I would rather stay on the least expensive side so a little clearification would be great.

I'm no expert on the subject, so take my advice with a grain of salt, but I think you can use any Master Cylinder, you just need a disc/disc proportioning valve.

We need more details to give you any specific master cylinder bore size recommendations. Wilwood makes several different calipers with several different piston area options, so knowing which calipers you're running along with the piston area of said calipers would be important information in sizing a master cylinder. As for the rear, a no-name brand could mean different things to different people. I'm assuming you're talking about a GM small-metric caliper setup with either front (w/o PB) or rear (w/ PB) calipers like those used on the 1979-1981 Firebirds, and 1978-1985 Cadillac Eldorados, etc, but that may not be the case. Either way, caliper piston area varies depending on whether you're running fronts in the rear versus rear calipers.

Also depends weather power or manual. For power brakes a 70 Corvette master from the parts store is a cheap experiment until you find out what it likes?

As Tobin mentioned, without more technical specs, it is all a guess.

Depends if you want functional with a decent budget or bling. Tobin helped me out too BTW. He knows brakes!!!!

I converted my 442 to disc/disc and I used a brand new Raybestos 1977-82 Corvette disc / disc master.
Both my classics are power brakes. They are $50 shipped from Rock Auto. http://www.rockauto.com/dbphp/x,carcode,1041062,parttype,1836,d,1977_CHEVROLET_C ORVETTE_5.7L_350_cubic_inch_V8_4BBL_L_Master_Cylin der.html
Solid as a rock, and beefy. Just primer and paint, bench bleed, and you're golden.

Combine that with an Adjustable prop valve (http://www.jegs.com/i/JEGS/555/63020/10002/-1?CT=999) from Jegs ($35) for the rears inline under it.

I also used it in my 1978 pro-touring z/28 as well.

I used a mastercylinder and power booster out of a 2001 camaro it was a very cheap and easy swap with minor fabrication some grinding and welding . I paid 40$ for whole assy at a u pull it yard . Pascals law comes into play as to how your set up is going to work correctly .
