Possibility the stop bolt may break loose on the hydraulic brake pedal. If this should happen, while it will not affect the braking characteristics of the vehicle, it will allow the pedal retractor spring to pull the pedal to a higher than normal operating position, and might cause the driver to be delayed in locating the pedal in an emergency stop. (correct by installing an improved brake pedal. )
