The left front brake caliper was siezed up on my truck. Both calipers looked pretty rough so I replaced both of them and put new pads on. Now the left one seems like it's sticking a little again. Also alot of times my brake pedal feels like trying to mash a concrete block for a few seconds then it softens up. I bled the brakes until no bubbles were coming out when I put the new calipers on. The hard pedal issue was there before I installed the new calipers. Could this be a vacuum pump problem? The pully on the vacuum pump looks pretty rough, looks like rust and a lot of gunk on it, I was thinking of taking it off and cleaning it up to see it that helped any. Thoughts?
Okay, I'll try those. As far as one caliper feeling like it's sticking, I figured that out. It seems that if you put a brake pad on backwards to where the metal side of the pad is contacting the rotor, they don't work very well! I'm such an idiot!
