    You have this figured it out. I'll bet you a stale donut that what is happening is the bad wobbly wheel bearing is letting the now wobbling rotor kick the brake pad which pushes the piston back in the caliper. You hit the brakes & the peddle is now longer than it should be. New wheel bearing is your fix.

    You may need a new caliper in the rear. If you do do not buy a rebuilt, thay are all junk. Buy a new one from Steven at eMINIparts.com.

    Let me us know how this turns out & where to send a stale donut if I'm wrong. :donut1:

    I was struggling to make sense on how the wheel bearing played it's role but what you said makes complate sense. Let's just put it this way the bearing was so bad I'm surprised the rotor didn't contact the carrier for the wilwoods. I'm weary about the right rear caliper but I will definitely check the link you provided as I was checking rebuilts. Curious as to what makes them junk though?

    There used to be good rebuilds out there, but over the years the quality of all rebuilds has fallen off. I put 2 rebuilt calipers on the back of my MCS. They lasted a while & went bad. They were replaced under warranty & those went bad too. IIRC they lasted about a year or so each. I bought new calipers & they were doing well when I sold my MINI & are to this day. I value my time & doing the job 3 times was a real pain.

    I can understand that, Im not a fan of doing the same job over and over. Guess my last question is if I end up replacing the right rear should I do the left as well or just wait for it to have and issue? I'm not 100% the right is in trouble but it definitely felt different turning it in.

    I'd probably wait. Check it over & make sure everything is working correctly. I had problems with the parking brake part on both my oem calipers. That was also the failure on the rebuilds I had.

    I would change out all four calipers. If one of the oem caliper wore out, the others can't be far behind.

    Good advice! I would fix the bearing First and see what you have after that.

    Can't tell if this is sarcasm, but the fronts aren't even oem anymore lol.

    I already replaced the wheel bearing. Just need to drive it a bit to see if the issue is gone.

    No, I meant it, I would have put an emoticon afterwards if I were trying to be funny. If the fronts are already new, I would definitely change both rears. I would never change just one caliper.

    Good to know, I agree I wouldn't change just one on the same axle. Not sure if they were all OEM I would do all 4 but definitely both rears if I change one.

    I have drove a little bit since replacing the wheel bearing and messing with the rear calipers. Brake pedal feels good, I figure after a couple more drives I will know for sure if what I did fixed the issue.

    I'm pretty sure you have it nailed. Now about that donut? :donut1:

    I believe you are correct, after going for a few drives the brakes have not had the issue, the pedal feels better than before actually. No donut for me, not allowed carbs on my diet :(
