What Happens When Front Wheels Lock Up?

[Elsie]

Front wheel brake lock-up occurs when excessive braking force is applied, causing the front wheels to slide instead of roll. This is extremely dangerous in emergency situations because steering becomes nearly ineffective when the front wheels are locked (i.e., sliding). Below is additional information: ABS: ABS stands for Anti-lock Braking System. Function of ABS: The ABS continuously monitors the rotational speed of each wheel through speed sensors installed on the wheels or drive shafts. A computer calculates the wheel slip ratio (used to determine if the wheels are locked) and compares it with the ideal slip ratio. Based on this comparison, it makes decisions to increase or decrease brake pressure, commanding the actuator to adjust brake pressure promptly to maintain optimal braking conditions for the wheels.
