2. Review of Basics In terms of energy what do brakes do?
Convert mechanical energy to heat energy.
Why are disc brakes better than drum brakes?
Disc brakes dissipate heat more efficiently.
Which does more braking? A braked turning wheel or a braked locked-up wheel?
Braking only occurs when the wheel are turning,
