What is a normal temperature?

Slightly warm to the touch. Definitely nothing that will be uncomfortable or burn you.

Heat can also come from the sun or warm tires. Just make sure the hubs are not noticeably warmer.

Or the heat source could be from a malfunctioning break, etc.

Temperature alone is not a fool proof way of checking whether a bearing needs servicing. I believe it is a rather poor way. If it is the bearing heating up the wheel hub, it could be too late to save that bearing. Even if it's not to late, do you want to service it on the road, possibly in an inconvenient and unsafe location? I would much rather inspect and do my preventative maintenance while home. :@

I am not saying not to check the temperature of the wheels while on the road, just don't wait for a abnormally high temperature to take action.
