Passenger side rear wheel not rotating in gear
I am having a weird issue with my 05 X5 3.0. I had replaced all the rotors/pads/brake lines and bled the system. I tried to drive the car around the block and noticed that the passenger side rear wheel not rotating/has a drag. I drove home, put the X5 on jack stands and removed the wheel hoping it was a stuck piston/caliper. I replaced the caliper with a used one and still have the same issue. While the car is on jack stands, I've started the X5 and put in reverse to see if the wheel is rotating. And no luck. I had opened the bleeder screw and fluid started coming out and and I gave a little push on the rotor and it started rotating. I went in to the car and pressed the brakes and there was very bad pulsation and the wheel stopped rotating again. I tried to use a 36mm socket on the axle nut and started turning the wheel with a ratchet and the wheel spins. I had also removed the parking brake hardware and no luck. Any thoughts on what is causing the issue? I was wondering if the ABS module is going bad, but I don't have any lights on the dash.. Could this be a pressure sensor issue? Any other tests that you could think of that I can perform? Thanks,

I think you might have some air in the system.

Thanks for the reply. Do you think this is not causing the piston to "uncompress" after I press and release the brake pedal?

Yes, that could very well be. A volume of air under the normal residual pressure could be your problem.

- Maybe the wheel bearing is seizing? But I doubt it.
- Just a thought.

It's not difficult to push the calipers off the rotor to eliminate that source of the problem. Pry the caliper apart and with car off the ground you should be able to turn the wheel and have the opposite side turn the other direction.
If as suggested above an air bubble is pushing the caliper tight the pads will snap right onto the rotor as soon as you let go. Sent from my iPhone using Tapatalk Pro

Question, is there anyway I can remove the caliper and put the car in gear and test on jack stands? I am worried that I may pop the piston out of the caliper when I press the brake pedal to change the gear... With the caliper removed and the car in gear, I want to see if the wheel is rotating..

You can avoid the piston pushing out by putting something in the way such as the old rotor. I don't know the amount of force so I don't know if wood is strong enough.
Re-reading I'm seeing you are just taking about pressing hard enough to get out of park. Wood would be enough for that. You should also be able to get the parking brake to stop the rotor to safely put into park. It sounds like the parking brake is adjusted too tight on the one side. You said you removed the p brake hardware? Eg removed the rotor and took out the brake shoes? That's a lot of work or do you just mean the external gizmos? Sent from my iPhone using Tapatalk Pro
