Help. I could really use the Planet's vast knowledge right about now.

I have a 2005 Hyundai Sante Fe 3.5L. I just replaced the rotors and brake pads on the front. It was driving fine and the brakes were working fine. But the ABS and TCS lights were on for some reason.

A little while later the wife started driving it and the brakes were kind of grinding. Well, not grinding. More like buzzing. It also lost most braking power. The ABS and TCS lights were no longer on.

I have taken everything apart and put it back together again a couple of additional times and still can't find the problem.

This seems to be an intermittent problem. It doesn't always happen right away. But almost always seems to show up if I stop, turn off the engine, and then start it up and drive again.

Is this something I can fix or should I take it to my mechanic? I am okay with basic repairs but don't have the tools or know how for anything more complex.
