Problem after installing SPC UCAs

So I just installed my SPC UCAs yesterday and got it aligned today. The truck drives wonderful. But I have two issue, when I am applying the brakes the brake pedal shakes a little bit, makes a small sounds (like something is engaging, my guess it's something to do with ABs) and my steering pull jerks to the right. This occurs right before I come to a completely stop. I also noticed that when I do not come to a complete it the throttle response is a bit delayed. It's never done that before until today.
The second issue had was that my slip indicator light came on when I was making a turn and when I got on the on ramp the same thing happens but this time the buzzer came on as well.

Has anyone had this issue, or any idea what it could be, what to look for? I'll be looking into this tomorrow morning and would love to hear your thought so I know what to look for. As of right now all I could think of is that I pinched or did something to my ABS. But the ABS light is not on.

I would guess your right front abs sensor. Pulling to your right could be from your right front brakes with no abs vs the left front with abs. The whole system on the 2001/2002 is pretty complicated but I would start with the right front sensor. Remove it clean it and then trace back the wires
 
Braking problem after installing UCAs

I would guess your right front abs sensor. Pulling to your right could be from your right front brakes with no abs vs the left front with abs. The whole system on the 2001/2002 is pretty complicated but I would start with the right front sensor. Remove it clean it and then trace back the wires



Cleaning the sensor seemed to work. I cleaned both front and rear ABS sensors and it hasn't done it since. Hopefully it stays that way, id hate to replace the sensor. They aren't cheap.

Also after researching all morning it looks like I also need to recalibrate my Yaw sensor. That's why the slip indicator light kept coming on. Does anyone have the missing picture in this thread?
