I can be a serious idiot, I had the parking brake on and I drove for a couple miles(kinda got on it too). I was tipped of by the "you're an idiot the parking brake is on light ". I'm having a serious hard time even admitting I did this on a public forum. I swear I'm usually not this dumb, I swear!

My rear brakes are squeaking a bit now(AXXIS Ultimate pads in the back) and I'm not sure if I should be worried. Any possible damage short of a little used up brake pad? I'm just not exactly sure how the parking brake works with the hydralic brake system and I'm feeling too lazy to look it up in the factory manual tonight.

Any educated thoughts? How's that fancy parking brake work? Any possible damage?
