this is on a 69 GTX, please tell me about the block..

[Lineman]

This is on a disk brake car and and the restriction valve or whatever you call it is in the line to the rear brakes.. Please tell me about this block, I thought this is a proportioning valve and distribution block? And is it the same for disk and drum brake cars? And what exactly does the pin do that the wire attaches too?

Thanks

Jay

The wire and connector go to your brake warning light. If for some reason you have a failure in either the rear or front brakes the proportioning valve switches to shut down flow of fluid to the leaking section of the brakes. The shuttle inside the brake prop valve then moves to close a contact inside which triggers your brake light telling you there is a problem.

I have the same valve on my 69 Charger. It was a 4 wheel drum set up. I now have 4 wheel disc with the same valve. Yours looks to be screwed up at the switch. Here is a pic when I tore my car apart.

Thanks, yeah my little plastic insulator is missing.. So that jam nut must hold that pin out for something going on in the valve? Looks like I can get one from Inline tube.. I will call them tomorrow and I will check the rod depth.. and see what I have.. I have been messing with these cars off on all my life and the stuff I didn't know..

What kind of problems are you having?

You could contact inline tube they sell whole distribution block. Maybe they can sell you a switch or tell you where to get one. Probably not. Seen switches on ebay occasionally but $$. Used blocks on ebay can $25 to $45 with shipping An hope switch works?
Inline tube website, they don't list switch separately.
