I read your post on disc conversions and it has a lot of great information. Thanks. I have been thinking about doing the conversion and so far all I have scrounged up are spindles. I guess the backing plates are available aftermarket. Is the proportioning valve available aftermarket also?

Thanks

Yup, from about 50 sources. There are a couple of choices in types, adjustable, delay (sometimes called "hold-off") or combo (distribution block and proportion valve combined). Deppends on what configuration you want under your hood. They all get the job done.

There's a ton of info on this in this forum. Or you can call/ e-mail one of the suppliers and they'll help you figure out what will work and the cost. Doug at Right Stuff is good ( 1-800-405-2000) as is the guy Olle used (see his product review).

I did 4-wheel discs on my car, so I used a Wilwood adjustable prop-valve. (About $50 through Summit)

I'm not sure where to get a factory style proportioning valve, but I've heard "Right Stuff Detailing" mentioned on this forum for a lot of the harder to find "correct" style OEM pieces.

I'm also doing a 4 wheel disk Welwood install. What did you do for your emergency brake cable install ? Did you use lokar cable setup, if so what p/n and price and how did it work out. Also did you use their master cyclinder and/or a power booster.
thanks in advance, Joe

I finally realized this string was addressed to Derek69SS, but I'll kibutz one more time. Pete Lohr has a e-brake setup available for rear discs that looks interesting:

I don't have E-brakes on mine. My car is an auto, and I never use the E-brake anyway, so I saved $100+ and used calipers with no E-brake.

My rear setup was done cheap:
Bracket that can be found on ebay for ~$85
11" Rotors from an 80 Trans-Am (rear)
Calipers from an 85 Camaro (front) - or you can use '85 Caddy Seville rears with E-brake

Powerbooster is stock Chevelle
M.C. is '68 Corvette
Proportioner is Wilwood adjustable.

I did the whole rear setup for ~$300, and all the parts other than the prop-valve and the rear caliper brackets were bought at NAPA, and can be replaced easily.
