Got the bump steer?.... (edit: juts brakes locking up I found out)

So. been a while, been busy, but found out the problem. It was the brake system. Something with the hydraulic locking up and not releasing. It was in an accident in 2015 and the guy that crashed it slammed both pedals....broke the gas pedal sensor and I thought brake was fine.... But I guess it wasn't releasing it like it was supposed to....So I guess when I pressed the brakes, they wouldn't fully release. Now it all makes sense. That is why it would start tossing the truck like that probably because one caliper wasn't perfectly smooth and at the perfect point/speed/pressure, it would be enough brakes to just catch on and toss the truck out of balance and then that would make it get tossed around even more. Upon checking my brake pads, rear right and front right were worn down almost completely. Put it on park for the winter to save some insurance, gonna start kicking tires when I get the time. But it wasn't anything with suspension at least. Just something with brakes locking up.
