The Difference Between Foot Brake and Hand Brake in Automatic Transmission Cars
1 Answers
The difference between foot brake and hand brake in automatic transmission cars: The foot brake generally refers to the service brake, which distributes hydraulic pressure or air pressure from the master cylinder to the wheel brake cylinders, then pushes the brake pads to friction against the brake discs (or drums), thereby achieving deceleration or stopping. The hand brake, also called the parking brake, operates on a different principle. It uses a steel cable connected to the rear brake shoe assembly to apply braking force to the vehicle. Explanation of car foot brake and hand brake: 1. Hand brake position: The hand brake is typically designed near the gear lever on the right side of the driver's seat. Pulling up the lever engages the hand brake, while pressing the button on the hand brake lever and lowering the handle releases it. Foot brake cars are generally automatic transmission vehicles, with the foot brake pedal located where the clutch would be (slightly higher position). Some people mistakenly confuse it with the clutch pedal. To release the foot brake, simply press it down. 2. Return spring: The hand brake system includes a return spring. When the hand brake is engaged, the spring stretches; when released, it returns to its original length. With prolonged use, the spring may deform. Any component subjected to long-term, frequent use will experience reduced effectiveness. This doesn't mean "don't use it," but rather that components should be used normally according to their characteristics. The foot brake serves as an emergency braking system that applies braking force directly to the wheels.
