I installed a disc brake conversion on my 72 vert. It uses the combo pro portioning valve. I just noticed that there are not enough ports for the front brake lines. I saw in one of the other threads that some replumbing is required. I assume I would T off the front port for the front brake lines?

 

should be enough ports on the correct proportioning valve... (two on the forward end at about 45 degrees up and down) (two to the master cylinder on top) (one at the back for the rear brakes which tee off at the differential.)
Be careful of the routing of the brake lines up there... they get kind of close to the exhaust system.

 

If you don't have enough ports, you most certainly do not have the correct prop valve. Here's what the correct valve should look like:



Note that there are two inlets from the M/C, two front outlets (one for each front caliper) and a single rear outlet.

 

Thanks for the responses. I had the correct valve. I kept missing one of the ports on top. I got it plumbed in correctly today.
