New brakes

My calipers started locking up on the way home the other morning, when I would brake it was pulling to the left really bad. So I went to advance and got new calipers, rotors, bearings and pads and put them on yesterday.

And here's one of the truck with the Chrome Eskies I got off of Craigslist.[IMG][/IMG]

what you could do is test to see if the pistons in the calipers are sticking or its your lines. all you do is you try to push the piston back into the housing. if the piston does go back inside then it could be your brake lines. but good luck. you could also just redo it like your going to do lol. but if it still dont work then its most likely your lines. my best guess. and .y .02.
