Had a problem...any thoughts?
My C6 Z51, 6spd....every option.... had a problem today and I was hoping someone might have some ideas about it. I was pulling into a parking space at a restaurant when at the last second I decided the space wasn't wide enough so I stopped quickly, backed up and straightened out the wheel..... as I started forward it felt like a brake was locked up.... I stopped, backed up a little and went forward again....same thing..... I forced it forward into the next parking spot and went into the restaurant ....figured I'd think about the problem while I ate. Afterwards I checked under the hood & under the car... nothing visibly wrong.... started the car up, backed out, and it has run fine the rest of the day. Any thoughts or input would be appreciated..... no sense even thinking about taking it to the dealer...they wouldn't have a CLUE!!!

As far fetched as may sound. I had a C3 years ago that had the same problem. I don't even know if the setup on the rear end on the C3 and C6 are the same in this respect. The rear end had spider gears holding the half shaft universals in the rear end. There could have been clips holding the universals to the spider gears. After the spider gears was a long square block with a hole in the center that had a shaft inserted into it. The shaft had a pin screwed into block that held the shaft in place. The pin broke allowing the shaft to drop down and bind against the housing locking up the rear end. Going forward would take the pressure off the shaft and it would drop into place allowing the car to drive forward. It would only do it at times at certain positions. If this has happened or similiar you will know it, when it happpens again. Just a thought. Hoping it is a different design and has nothing to do with what I describe.

I had a similar situation in my Audi TT, and I wondered if the self-adjusting brakes might have been attempting to adjust while backing...It seemed to only happen backing uphill. Was your parking spot where this happened on a slant?

Mine does that every time I back out of the garage. I'll back out and everything is fine. As soon as I start to drive away, there's an instant where it feels like the brakes are grabbing. After that it's fine again. I asked about this a while ago and it seems to be normal for the car so I'm not concerned at all.
Curiously, it doesn't do this unless the car's been sitting in the garage for a while. Could be rust, self adjusting mechanism, whatever.
