Its a dual over head cam engine if that is needed. I have changed both front pads, rotors, and calipers. And I noticed when its hot outside my caliper is sticking so bad that when driving for 30 minutes it was smoking when I got home and the rim what hot as hell. Now I'm no car mechanic, so be kind. But is it something simple or do I have to change the damn master cylinder? Thanks in advance. I took off the wheel today to look and the pads are just sitting on the rotor and I couldn't get it to move back.
