A hydraulic handbrake, also known as a hydraulic e-brake or hydraulic drift brake, is a device used in certain vehicles, particularly in motorsports such as drifting or rally racing. Unlike the conventional mechanical handbrake that operates using a cable system, the hydraulic handbrake relies on hydraulic pressure to engage the braking mechanism.
Here's a basic overview of how a motorsport hydraulic handbrake works:
Hydraulic System: The hydraulic handbrake is connected to the vehicle's hydraulic brake system. It typically taps into the rear brake lines.
Master Cylinder: The handbrake lever is connected to a master cylinder. When the driver pulls the handbrake lever, it activates the master cylinder.
Hydraulic Pressure: As the master cylinder is activated, it generates hydraulic pressure in the brake lines.
Calliper's or Drum Brakes: The hydraulic pressure is then directed to the rear brake calliper's or drum brakes. In some setups, it may be connected to a separate set of calliper's specifically installed for the handbrake function.
Brake Engagement: The hydraulic pressure applied to the rear brakes causes them to engage, leading to braking force on the rear wheels. This is independent of the vehicle's primary braking system, which is usually operated by the foot brake pedal.
Control and Release: The driver has control over the amount of hydraulic pressure applied by adjusting the handbrake lever. Releasing the handbrake lever allows the hydraulic pressure to dissipate, releasing the brake force.
The primary purpose of a hydraulic handbrake in motorsports is to facilitate controlled slides and drifts. In situations like drifting, where the driver intentionally induces oversteer, the hydraulic handbrake is used to lock the rear wheels, allowing the driver to initiate and maintain a slide. It provides a quick and direct way to modulate the brake force to achieve the desired level of rear wheel lockup.
It's important to note that the use of hydraulic handbrakes is often limited to specific motorsport applications, and their installation and use on public roads may not comply with road safety regulations. Additionally, modifications to a vehicle's braking system should be done with careful consideration of safety and performance implications.
