Re: 06 GT Air in rear break line
Hey Kris, The rears can be a pain - same system on the LT. I have found that if you open the bleeders too far on the ABS it sucks air into it at the base. I pack a damp piece of paper towel a round the base of the bleeder as that helps ensure I only see bubbles from the ABS. The reason you don't want to go more than half way has nothing to do with air. You can push the piston past its normal travel area and there could be corrosion there since it never wipes that area.
I also use an elevated bleeder bag/line and just crack open the bleed nipple and pump away, no press - open - close - release. It makes it go a lot faster and air bubbles will not go down hill. Just make sure you never let the reservoir get too low or you suck air into the circuit.
As far as I know BMW does not sell a repair kit for that connector. Best bet is to find a used harness on e-bay - look for early years on GTs and any LT from 2002 on up will use the same connector. I may have one in the shop - I'll check and see if that part can be removed.
Just looked at the one I have and I don't see a way to get the slide part out of the housing without breaking it. This may be a tough one to fix.
