I noticed that my left brake pad's were almost gone a few week's ago and they weren't that old! So I figured the caliper was bad or hung up! I replaced both side's, calipers and pad's and made sure there was anti-sieze where it needed to move! Now after a week, the brake's are pulling left when braking! What else could cause this? bad line's, master cylinder? Can someone help! This truck is draining me pretty bad after having the tran's re-done and then the turbo going out a week later! I hope it's an easy fix! Thank's
