What Is a Handbrake / Parking Brake? 🧠

The handbrake (also called parking brake or emergency brake) is a secondary braking system designed to:

> Keep your vehicle stationary when parked.

Unlike the main brake:

It works mechanically

Uses cables or electric motors

Operates independently of hydraulic system

Even if your main brakes fail, the handbrake can slow down or stop the car in emergencies.

—

How the Handbrake Works ⚙️

When you pull the handbrake lever or press the parking brake button:

1. A cable or motor activates

2. Rear brakes engage

3. Brake shoes or pads clamp

4. Wheels lock or resist movement

5. Car remains stationary

This system bypasses:

Brake fluid

Master cylinder

ABS system

Which makes it extremely reliable as a backup safety system.
