Re: Rig pulling to right when braking

There is also a fundamental design characteristic that causes the K/V trucks to go to the right during braking: the fore/aft steering drag link is trying to be compressed by the front axle windup. Since it can't be compressed it physically inputs a RH turn into the knuckle or, conversely, can also roll the steering wheel to the left. This is common on Blazers (shorter wheelbase makes them less stable and makes the phenomenon more obvious) and with 2 leaf front springs. Adding 3 leaf front springs (or a traction bar) to minimize axle windup helps the situation.

If you exhaust all of your brake options I would look at that next.
