If drums were that great, wouldn't they still be putting them on new cars?

Very good point.

How often does a vacuum booster fail, brakes get hot alot more than booster failure. Disc brakes is the first modification on any drum brake vehicle, car or truck. Once you have been in a bad place with drums fading, you'll dump them soooooooo fast.

Knock on would I have never had that happen. Maybe I'll go to disc brakes before it does happen to me.

By applying resistance, or friction, to a turning wheel, a vehicle's brakes cause the wheel to slow down and eventually stop, creating heat as a byproduct. The rate at which a wheel can be slowed depends on several factors including vehicle weight, braking force and total braking surface area. It also depends heavily on how well a brake system converts wheel movement into heat (by way of friction) and, subsequently, how quickly this heat is removed from the brake components. This is where the difference between drum brakes and disc brakes becomes pronounced.

It is all making sense to me now.

Thanks for being patient with me. Sometimes (all of the time) I am a little thick headed.
