What is the minimum cooling period between rotor brake applications?

• A. 3 minutes
• B. 7 minutes
• C. 5 minutes
• D. 10 minutes

Answer: (C)

When you apply the rotor brake, a lot of heat is generated in the braking assembly. The brake needs time to shed that heat so it stays effective and doesn’t overheat or wear prematurely. The minimum cooldown period is five minutes because that’s the published interval that allows temperatures to drop to safe levels before the next rotor brake application. Shorter waits, like three minutes, can leave the brake too hot; longer waits, such as seven or ten minutes, are not necessary for the minimum requirement, though they would be safe if you’re seeing high temperatures. So five minutes is the appropriate minimum cooling period between rotor brake uses.
