Definition
Independently operated wheel brakes on the main landing gear, applied by pressing the top portion of each rudder pedal with the toes. The left pedal controls the left main wheel brake; the right pedal controls the right main wheel brake. Each brake can be applied separately or together, allowing the pilot to slow the airplane, hold it stationary, or assist in steering during taxi.
Plain English
The brakes for the airplane's wheels, worked by pushing down with your toes on the tops of the rudder pedals. Left pedal stops the left wheel, right pedal stops the right wheel.
Context Anchor
Encountered during taxi, before-takeoff checks, engine run-up, and any ground operation where the pilot must control the airplane’s movement.
Derivation
Called 'toe brakes' because the pilot uses the toes (the upper part of the foot) to press the top section of the rudder pedal. The lower part of the same pedal is pushed with the ball of the foot to move the rudder. The name simply describes which part of the foot operates them.
Why Pilots Care
They allow the pilot to control speed and make tight turns on the ground using differential braking.
Intuition Check
Toe brakes are not a separate hand brake and they are not used in flight. They are foot controls for the airplane’s wheel brakes, used while the airplane is on the ground.
Example Sentence 1
During the before-takeoff check, the pilot held the airplane stationary with the toe brakes while advancing the throttle for the run-up.
Example Sentence 2
During the before-takeoff check the student verified both toe brakes operated smoothly.
