did you bleed the brake ? front left to back right and front right to back left ? my 91 explorer did the same thing until i went back and bleed them. it should help. did you compressed the caliper out all the way when you changed the bakes cause if you dont then it will be a tight fit and the brakes will stick to the rotors which will cause them to warp the roto and your pads to go bad . this should help .oh and by the way make sure the line going to the caliper is not twisted.

 

thanks man ill give it a shot. i havent had a change to go work on the brakes but ill get back at yall when i do get a chance later
