Hey guys, need a bit of advice here.

Changed my pads, went for a drive.
Pads felt like they were grabbing slightly when brake was released, now they aren't.
I took the car for a drive, did some slight braking about 3 or 4 times, no complete stops.
Then did some harder braking, again no complete stops, pulled into my driveway and i thought my car was on fire, i couldn't even touch the rim it was that hot.
(I really didn't think I was braking that massively)

Anyway, now I have brake shudder under hard braking. Did i heat the rotors up that much that they warped?
