A hydraulic handbrake system designed specifically for the BMW E46 chassis replaces the standard, mechanically actuated parking brake. This modification enables the operator to independently lock the rear wheels via hydraulic pressure, offering enhanced control during specific driving maneuvers, particularly drifting and rally driving. This system generally comprises a separate master cylinder connected directly to the rear brake calipers, bypassing the factory parking brake cables.
The implementation of such a system offers increased braking force and more precise modulation compared to traditional cable-operated handbrakes. Its application in motorsports allows for quick initiation of slides and maintaining a desired angle of attack. Historically, similar systems have been prevalent in rally and drift cars due to their robust performance and immediate response. However, installation may require modifications to the vehicle’s brake lines and interior.
