Helloooooooooooooooooooooooooooo! could you please post the problem/cause/fix for the brakes not releasing,to help others.thanks
I'm sure by now you have an answer. In the past if I had similar problems it would have been a sticking piston in the calipers. I'm sure with all the work you had done the brake fluid was changed too. Just want to hear the solution.
