Describe a safe brake check procedure on a patrol bicycle.

• A. Spin wheels and listen for squeals only.
• B. Check the brakes after the ride.
• C. Test braking by stopping abruptly from high speed.
• D. Spin wheels, check both front and rear brakes, ensure pads align with rims or discs, test for even braking, and listen for rubbing.

Answer: (D)

The essential idea is performing a thorough pre-ride brake check that verifies both front and rear brakes are working correctly and won’t cause issues on patrol. Start by spinning each wheel to feel for any rubbing or drag and to listen for unusual sounds. Then test each brake individually, applying the front brake and the rear brake to ensure both engage smoothly and with adequate stopping power. Next, inspect pad alignment: make sure the brake pads contact the correct braking surface (the rim on rim brakes or the rotor on disc brakes) and that there’s proper clearance when the brakes are released. Finally, check that braking is even across the forward motion—no pulling to one side—and listen for any rubbing when the brake is released, which can indicate misalignment, a loose caliper, or a warped rotor.

This approach is comprehensive and directly addresses common brake issues that could compromise safety on patrol. The other options fall short: they don’t verify pad alignment or even braking, they only focus on sounds or wear after a ride, or they encourage stopping from high speed, which is unsafe.
