obp Motorsport has a wide range of lockable and non-lockable hydraulic handbrakes for drifting, rally and autocross. The hydraulic system is fitted in addition to the original cable handbrake and is used to drift or turn the car where there's not enough wheel lock for tight turns. obp have developed an adjustable lockable lever for the hydraulic handbrake. The lever provides a temporary park brake allowing the brake to be locked when stopping at time checkpoints. It is NOT intended to be used as a permanent park brake.
