Default Started and drove car for first time in over a month. Brakes make a "thud-thud-thud" sound with

a nasty vibration. Brakes were fine last time I touched the car. Doesn't seem like rust or build up would cause this, but maybe i'm wrong? Brakes hardly bite just pulse and make a thud-thud sound. I drove the car around for a few miles (enough to warm the engine oil) so if there was build up or rust it would have been rubbed off. What do you think is causing this?

Cars sat for about a month and a half outside in cold weather and some snow.

mine did this. I did a few solid stops from 80-90 mph, and it took care of it.

Default Its got me a little nervous. It's pretty hard to stop and the thud is loud, you can feel it.

I'll try it in the morning when it's light out. I did a quick inspection to make sure the rotors weren't cracked and didn't see any visible cracks. Brake pads all in there too :/

I did some moderate hard braking and it was just louder and thud-ed harder.

Seems to be the general consensus. I'll give it a shot tomorrow.

Default 5th - just some rust on the rotors, same thing after my car sat at the body shop for a few weeks.

Just brake HARD a few times and you'll clean it right up.
