I posted before the Old forum became the new forum and now the new forum is not old and this is new I guess About my front brake just locking up during some Hot days here in Norcal. Seems the issue was simple, but lesson learned. I installed an oversize roter, went back to the stock brake line routing and then decided to go back to the CR routing brake line. In that I had been fiddling with the Brake lever itself adjusting it in and out. Seems that was the issue. I turned the Adjuster way in and this lead for no play in the handle or the plunger actuation. The hot weather simply expanded on that and locked the front calipers Well I think thats what happened. Re bled the brake last night still stiff and hanging, started looking at the adjustment and backed it out and the front wheel now spins freely and the brake is working as it should. Did not realize that the little adjuster at the lever would cause such an effect.
