Hello Felix:

If your "brakes not releasing" could possibly be under hood temperature 
related, then perhaps look into  the master cylinder being the problem.

On my urq, in stop and go driving, the under hood temps would go up, and 
the brakes would start dragging, getting progressively worse as the 
temperature got higher. If the master cylinder would get too hot to touch, 
the brakes would be dragging for sure.
Once back on open road, or after 10 minutes withe the hood up, all would 
return to normal.

Apparently not that an uncommon problem on 200's and 5000's..

New master cylinder ($50.00 at NAPA! Yea!) fixed it.

If it isn't heat related, the quite possibly the servo. No quick and easy 
answer for you for that..!
