Uhh, help! Please!

My parts are coming in tomorrow morning and should be up and running tomorrow afternoon or thursday morning. They're doing a flush on top of replacing it all, I just don't have the time necessary for something like this. Will get back tomorrow!

Getting ceramics on all four corners though, so something good came out of this ^.^

Since the BMC has 2 pistons (one for front, one smaller one for rear), it is feasible that the one for the rear somehow seized. Keep us updated!

Wish I had seen this earlier since I experienced this myself about a month ago.
In my case it was just that the rear calipers were worn out enough that the pins no longer slid freely. I replaced all the calipers/rotors/pads and the parking brake shoes. I haven't had a problem since.

Depending on the condition of the calipers it might be enough to just clean the contact area of the slide pins and re-lube them. In my case all of the rubber was shot and it was much easier to replace them than to rebuild them.
