I'm having a heckuva time trying to find parts for my '77 Dodge Tradesman I just bought. I'm tring to replace the proportion valve for the brakes. My local Dodge dealer is saying I could get a new one for 250!?! Is there someplace online possibly that's a good mailorder source for this stuff at more sane prices?

Why do you want to replace the proportioning
valve?

I need to replace it because it's leaking brake fluid!

Probably not the valve itself - pull off the lines and see about relpacing the ends (there was enough room coiled in at the factory to change them, Your Mileage May Vary). Possibly they have become corroded over time or have backed off slightly...

Anyhoo, that's the cheap way, and if that doesn't do it for you, get one from an aftermarket supplier - not only cheaper, but also adjustable.

That's probably true but everything is so corroded down there that I can't unscrew the fastners. I've tried a couple things like WD-40, etc. but I can't get 'em to come loose and the more I try, the more I strip 'em. I figured I'd have to cut all the hoses, put new ends and get a new valve.
I don't know what after market suppliers are out there for Dodge. I went directly through my local Dodge dealer and the best they could come up with was $250 for a replacement valve. That seems a little ridiculous for a part like this... but I'm still pretty new to this stuff so maybe it's totally reasonable?

Hi Poopville,
Do you have a switch on the valve?
the switch may be leaking.
Use brake flued to soak the threads for
two days to losen the rust.

The problem is, that valve is called a "combination valve" or a reason - it not only deals with proportioning, but it has the light switch on it, etc...

Here's an example of an aftermarket proportioning valve: Wilwood rotary valve.

I need to grab my "brake systems" book from home, then I can really give you a good answer..

There is something that resembles a switch on the front end of the unit. It's like a round, bulbous rubber thing with a metal pin sticking out of it. Can't tell if the metal pin is SUPPOSED to be poking out or it's just busted through. The whole unit looks like it's been sitting on the ocean floor for a hundred years or so.

Hi POOPVILLE
the pin sticking out of the end is the Hold-off Valve.
On the top in the center should be the Brake warning light connector.
Do you see where the leak is coming from?
You may be able to replace the bad part.
