Claim:
1. A line lock braking system for a vehicle, the system comprising: brake module integrated control unit (ICU) configured to selectively apply hydraulic braking pressure against front wheels and rear wheels of the vehicle; and a controller in signal communication with the brake module, the controller configured to: upon receipt of a request, initiate a vehicle line lock mode and perform a line lock braking of the vehicle where the brake module ICU is controlled to selectively apply hydraulic braking pressure against the front wheels and not the rear wheels such that the rear wheels are free to rotate based on a throttle applied by a driver of the vehicle; monitor, during the vehicle line lock mode, a number of rotations of the rear wheels while the front wheels are maintained in a substantially stationary state by the brake module ICU; upon release of a button being depressed to enter and maintain activation of the vehicle line lock mode, complete the vehicle line lock mode such that the hydraulic braking pressure against the front wheels is released; and deactivate the vehicle line lock mode upon determining the number of rotations of the rear wheels exceeds a predetermined number of wheel rotations during the vehicle line lock mode.
