disc brake plumbing???

I have a '67 chevelle that I just converted from front drum brakes to power disc. I bought an ajustable proportioning valve and mounted under the mastercyl. on the frame is the distribution block. The old mastercyl. was a single type, which I replaced with a dual. My question is how do I hook this up? Do I need the distribution block?

I would junk yard the lines from the m/c to the purportiting valve and the valve it's self from a mid to late 70's Camaro. When you remove draw a picture of how it's set up for later. Install and bleed without your ajustable valve. See how well balanced the brake are by panic stopping it somewhere safe and seeing how even the skid marks are. If the fronts are locking up more, add the adjustable valve between the m/c and purportiting valve and dial the brakes in from there. You may find that you don't need the adjustable valve as the late 70's Camaros are close in weight and braking to what you have now. Good Luck..

the car I am working on is a chevelle wagon. If weight matters the camaro is out. Any other suggestions? Also do I need to find a donor with front disc and rear drum?

The donor should be disk/drum and close to the same weight so a later wagon should work.

How many lines are coming from your master cylinder? Brakes are very basic when you understand fluid principals. If you have two lines coming from the rear chamber, send those to the front wheels and do not go thru any distribution block. Take one line from the front chamber and run it to the rear axle, using a flex hose going from the hard line on or near the frame to a hard line T block mounted on the rear axle housing. The adjustable proportioning valve should be in the hard line between the MC and the rear flex line. It needs to be mounted where you can get to it to dial it in. If your MC is higher than your front calipers and rear wheel cylinders, residual valves are not needed, however I have had better luck using them any way. If you use them, you need a 10 psi in the front and 2 psi in the rear. Also if used, you will need to block one line in rear chamber of the MC, and run a single line to a T block before running to front wheels. The residual valves should be installed as close to the MC as possible.

Having said all this, you can do a search of the Knowledge Base and find a lot of good info that has been posted in the past.

You might want to chaeck out Stainless Steel Brakes and other after market brake upgrade companies web sites for basic info and plumbing. I don't know if the 67 Chevelle came with front discs or not but you might want to check the service manual and other sources. I initially converted by 4 wheel drum brake 69 to Camaro to front power discs by using all the parts from a early 70's Nova. All the parts were there. You should try to locate one of the parts swapping guides to see what fits and what doesn't. I eventually put rear discs on the Camaro and if I had to do it all over again I would just buy an aftermarket kit. Check out these links for more info http://www.carcraft.com/techarticles/850/ or http://www.inlinetube.com/disc%20bra...on/dbrake.htm. There is a lot of information available on the web and you should also check out the knowledge base.
