Strange squeak from rear end after burnout (Video attached)
Today I decided to do a little brake stand just having fun in the GTA. Almost immediately after leaving the empty lot and making a turn I hear a weird squeak from the rear end. Never heard this before. Doesn't do it in a straight line, really only when making a U-turn turning the wheel all the way. It'll do it turning left or right. I got under and looked but found nothing of the obvious. The rear isn't grabbing or slipping, no other sounds except for the squeak and it's not constant. The video will tell all. What do you guys think this could be? Any help would be greatly appreciated.

If you don't have a line lock you probably glazed the pads and rotors bad. Then when you turn you're loading the tire causing the pads to rock and making that noise. There's probably a rust ridge on the outside of the rotor that's causing the issue.

Just did the rear pads not too long ago but they were the cheapest auto zone ones.
Haven't pulled the tires yet so I'm not putting anything past it.
Jonesy, I forgot for that moment that I had 4-wheel disc brakes and it could have messed something up. Definitely don't have a line lock. You make a good point, but wouldn't it make that noise all the time? Or like you said only when a load is applied?

Well drove the car last night and this morning and got everything up to temps and some, and the noise is completely gone. Tried to replicated it last night for my fiance and it wouldn't do it. I'm not complaining. But it wasn't for nothing

I've heard brakes do funny things at funny times. Never know what'll happen.
