Distinguish between mechanical handbrake and electronic brake
Latest update date: February 07, 03

Car handbrake (parking brake or emergency brake) is an auxiliary braking system used to keep a vehicle stationary when parked or in emergency situations.

In today's automotive world, the two most common types of handbrakes are the traditional mechanical handbrake (Mechanical Parking Brake) and the electronic handbrake (EPB) that exist side by side, each with its own advantages and characteristics. From a technical perspective, the handbrake is not simply a lever or a button, but a complex system consisting of actuators, control units and intelligent sensors, ensuring that the vehicle is kept safely stationary in all terrain conditions.

According to safety analysis data, vehicles equipped with an electronic parking brake system show a 37% reduction in parking-related incidents compared to vehicles with a traditional handbrake, mainly due to the automatic connectivity features and integration with other safety systems.” (European Vehicle Safety Institute, 2022, “Comparative Safety Analysis of Modern Braking Systems”, Belgium).

This article will take readers deep into the development history, detailed structure, operating principles, as well as analyze the advantages and disadvantages of each type of handbrake, helping you have a comprehensive view and choose the most suitable solution for your needs.

History of development of car handbrake

Car handbrakes have been developed through three main stages: simple mechanical handbrakes, improved mechanical handbrakes and electronic handbrakes (EPB).

  • Early stages: Simple mechanical handbrake

Mechanical handbrakes have been around since the early years of the automobile industry. In 1902, a new braking system was tested in New York, consisting of a flexible stainless steel band wrapped around a drum on the rear axle. This mechanism set the stage for the development of mechanical handbrakes in the following years.

  • Development Stage: The birth of the improved mechanical handbrake

By 1904, most cars were equipped with external brakes on each wheel. However, these brakes quickly showed their shortcomings, such as wearing out quickly and being ineffective when parking on slopes. This led to the introduction of the internal handbrake, which increased its lifespan to 1000 miles and significantly improved braking performance.

  • Modern Stage: The emergence of the electronic handbrake (EPB)

In recent years, the electronic parking brake (EPB) has become popular in many car models. EPB uses an electric motor to operate, bringing many advantages such as compact design, automatic features and the ability to integrate with other safety systems on the car.

What is a mechanical handbrake?

The handbrake is an auxiliary braking system on a car that operates independently of the main braking system. The main function of the handbrake is to keep the car stationary when parked, especially on steep terrain.

The mechanical handbrake consists of the following main components:

  • Handbrake required.
  • Brake cable.
  • Brake shoes or brake pads.
  • Brake drum or brake disc.
  • Springs and adjusting parts.

1. Operating principle of mechanical handbrake

When the driver pulls the handbrake lever, force is transmitted through the cable to the brake shoes or pads. The brake shoes press against the brake drum (or the pads press against the brake disc), creating friction and holding the vehicle still. To release the brake, the driver simply pushes the brake lever back to its original position.

2. Advantages and disadvantages of mechanical handbrake

Mechanical handbrakes have advantages such as simplicity, ease of use, low repair costs... however, there are still disadvantages such as: needing a lot of cabin space, uneven braking force and being easily damaged.

Advantage:

  • Simple, easy to use and maintain.
  • Low production and repair costs.
  • Operates independently of the vehicle's electrical system.

Disadvantages:

  • Need more space in the cabin.
  • Braking force may be uneven.
  • Easily damaged by environmental impact.

3. Variations of mechanical handbrake

Mechanical handbrakes come in two main forms:

  • Handbrake lever: Common on passenger cars and some commercial vehicles.
  • Pull-bar handbrake: Commonly used on some commercial vehicles.

What is electronic parking brake (EPB)?

The electronic parking brake uses an electric motor and gears to act on the brake pads. When the driver activates the EPB, a signal is sent to the controller, which then controls the electric motor to generate braking force. This system is integrated with the vehicle's ECU (Electronic Control Unit) to ensure precise and safe operation.

Modern features of EPB:

  • Automatically activates when power is off
  • Automatically release when vehicle starts and moves
  • Hill Start Assist
  • Integrated with electronic stability program (ESP)

1. Popular types of EPB today

3 types of EPB commonly found on modern cars:

  • EPB integrated on gear lever
  • EPB separate push button
  • EPB combined with Auto Hold function

2. Benefits of EPB handbrake

The 4 main benefits of EPB handbrake include:

  • Compact, space-saving design
  • Automatic features increase safety
  • Integrated with many driving support features
  • No need for periodic adjustment like mechanical handbrake

What are common errors and how to fix them with the handbrake?

Worn brake cables/pads, stuck brake levers are common faults in mechanical handbrakes. For electronic handbrakes, common faults include: ECU fault, electric motor fault and sensor fault.

Common errors in mechanical handbrake:

  • Worn or broken cable: Reduced braking efficiency, cable needs to be replaced.
  • Worn brake pads: Reduced braking force, brake pads need to be replaced.
  • Brake lever stuck: Due to rust or dirt, needs cleaning and lubrication.
  • Solution: Check and replace damaged parts, adjust cable tension.

Common errors in EPB:

  • ECU error: EPB system is not working, need to check and repair ECU.
  • Electric motor fault: Electric motor is damaged and needs to be replaced.
  • Sensor error: Sensor is damaged, needs to be replaced.

Solution: Use specialized diagnostic equipment to identify the fault, update the software or replace the damaged component.
