I've been noticing that my truck was progressivly getting touchier and touchier in fact 30 mph was about as fast as I could go. So the other day at work we were kinda slow so I figured that I'd have a quick peek at it so I pulled it up on the alingment rack thinking I was going to find majorly out of balance tire(s) (I thought my equal may have clumped). low and behold I couldnt turn my rf wheel by hand so (the caliper was tight). I ran and got a caliper real quick and threw it on as we got busy again. I wanted to look at it more but just wasant able to so I ended up driving it home with just a new caliper and to my suprise it was fine!
