which proportioning valve?

[rampage]

i did the 5 lug conversion on my rampage using front spindles and brakes from an 89 spirit and the rear discs with drum style e-brake. what proportioning valve do i need? and where might i find it besides a junkyard? thanks, its soo close to being road ready again .

I was thinking about going with an adjustable like this one.

Are you ditching the goofy weight compensating valve that is attached to the rear axle?

I'm using a 90 Daytona 4 wheel disc master cylinder and proportioning valve. but any p-valve off a 4 whel disc car will work.

Thumbs on that. I tossed my rear prop valve also.

So you have 4 wheel discs? How does it work? I've done the conversion to 5 lug with drums on the rear. I had seen someone on here comment the rear discs are always locking up too soon. (proportioning valve would solve this) but it made me wonder if it was worth bothering finding rear discs.


What do you think? And if so, how did you manage the e brake set-up?

P.S. my Rampage is years away from being on the road so I have lots of time to think about it.

its stops awesome. I've never had my rears lock up. and I did away with the rear weight valve also.

I will have to keep a look out then. Geez there was a T2 89 Lebaron in the local PnP 2-3 weeks ago. Oh, and how about the e brake?

Here is some good info on the stock valves.

The aftermarket one might not work that great given that it is designed more for the RWD crowd and has a much higher slope than a FWD car normally has.

It is also not setup for diagonal brakes so you would have to re-run all of your lines.

E-Brake is easy if you get the discs with drum style parking brake. You reuse your brake cables. I don't have any valve in the rear, it must have been removed by the previous owner. Replacing the proportioning valve has been a pita because the fittings were seized and the lines broke when I tried to remove them. I should have done this when I was replacing the k-member, i would of had plenty of space to work. I ran new lines up front and spliced the rear ones with compression fittings.
