Is the stuck caliper only on one side? Front or rear?

Yeah that makes sense. Thanks for the information,

Its on the right front

I think you have to pull the caliper and have a look.

i had that problem about a month ago where my right front caliper locks and make it shack like crazy on the left front end of the X. i did enough research on getting a kit & fixing it but it seems too much of a head ach and if u miss 1 step or dont fallow it the right way it well prevent problems within the caliper in a short period of time... its just not worth it.. dealer wanted too much for each caliper but i got mine for $85- rebuilt and they sure were BMW calipers and i was happy when i got em.. i replaced both calipers while am at it.. ( sure if one side goes bad, the other well soon, thats how i look at it.).. dont pinch the brake line or anything, u well damage em.. just take the caliper(s) out and LEAVE THE RESERVOIR CLOSED dont open it, when ur done with the job just bleed ur lines( mine took about half a bottle of break fluid that i picked up from the stealers for $4 something after i did both calipers. i aslo did a brake job and rotors changed as well.

Hey, soooo it was your caliper :) I knew I remember something I read before. I think if you have your brake pedal pressed and held with something you will be ok. That what is asked if you change your brake lines. Im glad you solved it. Cheers

ya but its not that hard to bleed the brakes, all u need is someone settin inside and bumping the brake padel about 4 times and the last time just tell em to hold it all the way down while the other one is by the calipers opening the lil breather thats by the calipers letting the air out and some fluid with it as well and tighten it back on just do it a couple times for each side and u should be fine... and yup that was me mate:D... it was a BI alternator calipers brakes all at once.. one thing goes out another thing goes with it lol
thanks mate everything is under control now:thumbup:.. its just a mod-fever season:rofl:

I didn't read the whole thread, so sorry if this has been answered. You can pinch the line using a C-clamp or something w/ a flat area like that...just don't use something that has a hardedge to pinch it, like Visegrips.

I"ve seen caliper rebuilding kits on eBay for next to nothing. Before that though, I'd flush the brakes. If you goto your local Harbor Freight you can either buy a one man brake bleeder...it's basically a silicone line w/ a one way valve in the line. Otherwise you can just use like 3-4ft of line and hang some of the line above the height of the drain valve so it doesn't all drain out. Bleeding brakes by yourself isn't hard, but I'd do that before I start tearing calipers apart.

I have rebuilt two calipers on my X and it's a simple process. And does not take much more than an hour to do.

Rebuilding our calipers seem to go over pretty well? I can't decide if i want to get the rebuild kit, buy a new one for $260, or get a reman one. I don't put any aftermarket parts on the X5 ever, only ever oem BMW.

Any suggestions? I am going to do both the front ones either way.
