Well since mine is a 84 it has the regular proportioning valve, which is the cast piece in the pic. And is the same unit used on most full size mopar cars, van and trucks from the early 70's on up into the 90's.



Ma' Mopar based the proportioning valve on weight, so the full size cars, vans, and trucks were generally within the same weight category,so they all received essentially the same unit. I have confirmed this with the dissection of a proportioning valve from a 71 Chrysler 300 and a 86 dodge ram D250, and from looking at the units on many cars and trucks over the years.

I can snap a pic next time I'm under the truck...but it looks exactly the same as the cast piece in the pic.

 

I just did a complete brake job on a 97 ford f350 and it is has the same parts as in our dodge just diff. front calipers, even the RWAL is the same only its mounted up front by the engine . and it was suffering from week brakes .I ended up replacing everything on it too. and the ford calipers are way harder to bleed then the Bendix ones on our 1st gens

 

Gotcha Thrash, thanks for the info. I'm just trying to figure out if the prop valve (Aluminum piece in the pic) is actually stock or not so I know which direction I should go when I put it back together.

Thanks again

got a sol the line loc is supposed to go to the front brakes not the rear.

 

its a jeep, not a drag car.

I used it for a parking brake and to do front digs(too cheap for cuttings brakes at the time), although I imagine the drums are the reason it doesn't hold for more than a day or so when used as a parking brake and most likely the reason its not legal in a lot of states to do so.

 

I have several trucks equipped with old-school MICO brake-line-locks.

I have complete confidence in their holding abilities and many times they have held big loads of cattle on gradients with the cattle thrashing around.


The reason it is not a good idea to use them as the only parking-brake is not any fault of the line-locks themselves, but due to minute seepage of the wheel-cylinders and any other possible leaks.

 

Did you retain the RWAL or bypass it ??

 

I bypassed my abs dump valve. Just have to be careful when empty and its wet.

 

Humm, my 91 has good solid brakes but my 92 is like stepping on an enema bag. I need to swap brake boxes and see if that is my problem. Squishy brakes and an automatic are a bad combo.

 

Your town and country came with the same proportioning valve that every other MOPAR car of that era came with. From a lowly slant-six A-body to big block C-barges.

To eliminate the ABS on these trucks all you really need to do is pull the ABS pump/valve and connect the lines together where it is at, then plumb the proportoining valve into the feed line, I'd put it under the hood so it's easier to get to. You might want to dial in a little more bias when you load it heavy.

 

I tried it and no help for me.

 

You gotta quit steppin' on them enema bags, Coug!!!!

 

What, pray tell, is an enema bag ??

Thanks.

 

You don't want to know Mark
