Hi everyone, not sure if I'm being really dumb here but gears and diffs and stuff are still a bit of a mystery to me. Basically, I've got the rear wheels of my Series 3 jacked up, and they are able to spin freely with the handbrake on. The handbrake works fine, stopping the drive shaft turning, but the wheels can still spin freely even if the shaft isn't moving. This can't be right.

Am I missing something? Cheers.

Take a look at this How a differential gear works - Boing Boing
Hope it helps.

Yeah that did the trick, obviously nothing wrong, I'm just being a bit simple...
Cheers.
