Actually, you're wrong. It was dry on the 25th July 1976. I remember it well. They gave us a national holiday.I know the sound you guys are talking about now.. I only get it after I have washed the car, moved the car back into the garage with wet brakes and the next morning the disks stick to the brake pads and it sort of pops as you move forward. You guys probably get it all the time, because it is never dry up there.
