i heard somewear if u take your porportionin valve out of your truck and run straight lies to the rear brakes it helps stopping with bigger tires,anyone hear of doing this,does it help stopping?:dontknow:

um.. i've never heard that.
I wouldn't think so, becuase your rig had drum brakes in the rear. The proportional valve also keeps a certain amount of pressure on your brake cylinders.
(drum brakes require more parasidic drag than disks)
I could be wrong as i'm not a toy guy, but it doesn't sound right to me

most of the time it works good. some people have found that their rear brakes lock up really easy though.

Under certain hard braking circumstances they can lock up and wont release, have 2 friends that it happened to, and both flopped their trucks, 1 going 90kmph and the other 50kmph. if you take it out, replace it with a variable rate proportioning valve, their about 80-100 bucks. you don't want full pressure going to the rear. if this rain doesn't get ya, one rainy day after a dry spell and you'll find out!

a few good threads on this topic on the marlin site, most guys replace it with an adjustable aftermarket unit mounted under the hood just after the master cylinder.
every thing you need to know.

Cut the load actuator arm and it will go to the the top where you get the most brake it allows for, I run 35" boggers and haven't had them lock up on me.
