Re: Brake Temperatures - 1940 Packard 160

The rear axle will run above ambient temperature if the car is driven much, due to normal friction and fluid friction in the axle lubricant. Some of that heat will find its way to the rear hubs and drums. If the brakes don't drag significantly, the heat is bound to be coming from normal temperature rise in the drive axle. Of course, brakes generate heat when they are used, and some heat from the engine will pass under the car and reach the rear axle.
