comment Does the age of brake pads make any difference?
Sorry, I did neglect to acknowledge that the properties of the brake pads can affect (1) how much heat goes into the rims vs. the pads and (2) how you use them, thus how quickly things heat up, thus what temperatures are reached. However, “effective at creating heat” is exactly the same thing as “effective at braking”. Conservation of energy is absolute.

I dispute your anecdote: the effectiveness of the brakes cannot affect whether overheating occurs, only how you use them. Any brake, if it works at all, converts kinetic energy (slowing you down) into heat. It cannot produce heat without also slowing you because that would be energy from nowhere.

comment Can I approximate how much air pressure is lost from disconnecting the hose?
@CareyGregory Yes, but this answer addresses the confusion that “the hose length and diameter” matter. Additionally, in my experience, how much air is lost by pulling the chuck off varies a lot and I don't think it could be usefully determined except empirically.

@CareyGregory Yes, real inner tube valves aren't separate. I cover that in the last paragraph. I've edited to emphasize that the first description is idealized.
