Adjust brake bias? New proportioning valve?
Hey guys. I’m looking for better braking out of my 02 Cummins.
It has 4 wheel discs and it does not stop like a 4 wheel disc vehicle at all.
Is there a way I can adjust the brake bias to take better advantage of those big rear discs? Do I need an aftermarket proportioning valve?
Any help would be appreciated!

Yep, aftermarket is the only way. Stock systems are not adjustable.
That said, when you truck is empty, you should be able to stand it on end with the brake pedal....... How old are your pads? What do your rotors look like? Sounds to me like both are going to be glazed, in which case, they just don't work very well.

I have no idea on the age of the pads and rotors either, they’re the ones that were on the truck when I bought it last year. I’ll start there and see how I’m feeling after, thanks!
I would go for some REALLY good grade brake pads....

Lots of opinions on what's 'best'..... Ceramics are generally considered 'highest performance', but, they also tend to be squeaky....... (which can be HIGHLY annoying.) Best bet is to poke around a bit, read some reviews, and decide from there. I don't go in for the drilled/slotted rotors though. All that does is give cracks a nice place to start.
