Wheels off ground = No hand brake

[the evil twin]

AHHHH. So it's the tailshaft that is locked / braked and not the wheels and it's the tailshaft being held stationary that holds the wheels stationary UNTIL they are lifted off the ground, so the hand brake doesn't act on the wheels at all, just the tailshaft.

Thanks ET, I owe you another beer. Awesome I've learnt something.

Nailed it dude ^^^^ ... (in fairness others said similar but I'll still take the Beer)

well the wheels will still spin one forward and one backwards with the tailshaft locked . me thinks ....

Hmmmmm....... that can't be correct...me thinks mate, 'cos what the handbrake effectively does in a GQ(dunno about a GU) is to lock the rear driveshaft from spinning. For example lift the rear wheels and shove a screw driver, tyre lever of something through the uni joint and try to spin either one of the wheels. You won't be able to do that. Don't damage the uni joint by putting too much force on the wheels though.

Yeah, but it works fine as long as the wheels on the ground. With my stock real LSD, it works off the ground as well(not it that helps )
