Hello everyone.

I need some help with a problem i'm having. I replaced the rotors, pads and calipers. When I hit the brakes hard the drivers side locks up and seems to stick. I replaced the caliper so I have no idea whats causing it. Could it be the master cylinder is going out? Could the break lines be the problem? The car stops much better know but from time to time it locks up.

 

try replacing the brake lines on the front they are old anyway. This has been suggested with good results on other posts.
