Well so far so good. I made a trip today where in the past when the problem existed by the time I got home things were locking up. The only change is that it is not as hot (95) as it was a month ago but still pretty hot here.
I got home at it was still rolling freely. It was a fair amount of braking for the trip on city streets and used the brakes as you normally would. Although it should be fixed, I will be real happy if it really is. Being a bit skeptical on this repair operation, I need to build confidence it will not happen.
