Default Braking Question 99 Ram 3500 Dually

I have Braking question on my ram it has abs front and rear not 4 wheel abs though. The pickup wire to the front driver wheel for the abs is broken which i could care less about the abs I don't like it any way. The problem I'm having is that the right rear wheels lock up way before the rest. It has a real good brake pedal high and frim very sensitive too. I looked into the metering valve and the plunger appears to be moving with the pedel like it should i belive. I don't know if the abs is causing this or if the right wheel is getting more hydrolic pressure then the the left.
Any Ideas?

May be a dumb question, but are the shoes on your right rear drum adjusted closer than on the left? I don't even know if that could cause such a problem but it seems possible...

Well, it shouldn't be locking up at all if you have ABS.

If you're saying that the ABS system is engaging prematurely, I had a similar problem with my 98 Ram a long time ago. A leaking axle seal boogered up one of the rear brakes, making them sticky, causing the ABS to fire prematurely and also below the threshold speed (where it wasn't supposed to engage at all). Take a look and see if there are streaks on the inside sidewall of your right rear tire.

the abs is dead for now the pickup wire on the front left side is broken and the abs doesn't engage at all. I already replaced the wheel seals so there isn't any gear oil getting to the brakes.

There's no such thing as a dumb question so my teachers alway said, I already adjusted the shoes back on that side and made no change.

Lubricate where the shoes ride on the backing plate. That can make the shoes grab if it is not moving smoothly
