Brake issues!

In order to properly install those brakes, the knuckle has to be grinded down for the bracket will fit properly. i just wanna make sure that was done on both sides. I'm assuming it was.

They won't install correctly without shorter slide bolts or grinded down like mentioned above. Just because they are newer calipers doesn't mean the piston will never rust and hang up in the housing. They are still 10+ years old. I'm guessing they are the aluminum PBR calipers. You could always remove them and install a rebuild kit (new pistons, rubber o-rings and slide pins). Either that or buy new remanufactured units or Cobra calipers (both with lifetime warranty). I wouldn't trust having sticky front brakes when 65% of the braking is done up front. Also with a piston that does not retract will cause the pad to hang on the rotor which means excessive pad and rotor wear.
