i removed my rotors this mornin to paint them black sanded them, got my 500* degree black paint and started painting them. after like 3-4 hours, they seem dry so i sand off the paint that got into the actual braking part, the part that makes contact with the shoe pad. then i put them back on my car the rotors still had a bit, a bit over here, another one there of paint. i thought "this will be no problem, the pads will get rid of this once i brake". well now i put everything back in its place, and go for a test drive! i go out and its not stoping good like it was. so i keep going and braking for a little less than 5 minutes or so. then i dont see any difference, its still not good enough. so i remove the wheels, and then see how hot my rotors and shoe pads are. i let them cool off for a while, sand the shoe pad, and the rotor again, and put them back on. i knew this was gonna work now. i get on my car and test drive it again. next thing you know, its still not stoping good! i drive rough(stop-n-go-stop-n-go...) than after 5 min i go back home. i get to my garage and its so hot smoke is coming out of the wheel area. i touch the wheel and its really really hot and it smells like when someone does a burnout. now my car is sitting there waiting for me to fix it but i dont know whats wrong! anybody know if i did something wrong? it was workin perfect just before i remove the rotors. my shoepads are almost new. anybody can help? thanx__________________
