That was covered earlier in the thread but unfortunately doesn't apply to 4.2L cars.

 

If desperate, remove wheels. Oh I already said that.

I'd apply power instead!

 

Not sure that removing the wheels would help. The cable would be under tension to apply the brake pads. No way of unhooking the cable or removing the caliper. I suppose cutting the cables would work but at ~$200 each, that's a little drastic.

Cheaper to call the auto association or go out and a buy battery and cables.

 

I've removed your link.

Not primarily because it linked to another forum but because the procedure doesn't apply to the OP's 2007 MY.
