While driving into Austria via the German side via Garmisch, with the very hot weather conditions in Europe this summer. Some of the exccess grease of the pre-deaparture lubrication went so fluid. And unfortunatley made it's way to some hot part of the front disc brakes.
-A huge smoke cloud surrounded the truck going downhill on the steep mountain road !
Luckily we managed to find a safe parking spot, where able to smore the now burning grease with our precious mineral water !
While the smoke disappeared we had a mandatory lunch.
