Methods and apparatus for controlling landing gear retract braking are described. A controller determines wheel speed data corresponding to a speed of a wheel of a landing gear. The controller determines wheel deceleration data corresponding to a rate of change of the wheel speed data. The controller generates a first control signal in response to the wheel deceleration data being greater than a wheel deceleration threshold. The first control signal initiates a wheel deceleration regulation process, the wheel deceleration regulation process to cycle an antiskid valve between a first valve position to release brake pressure from the wheel and a second valve position to cease releasing the brake pressure from the wheel. The controller generates a second control signal in response to the wheel speed data being less than a wheel speed threshold. The second control signal terminates the wheel deceleration regulation process.
