Vacuum Brake Boosters: Small Part, Big Impact

“Hey buddy, do you know why a truck’s brake pedal feels as light as a car’s, even though it carries a much heavier load?” My friend, a truck parts dealer on Nguyen Van Linh Street, Long Bien, asked me with a grin. This seemingly simple question reminded me of a small but crucial component in vehicles: the vacuum brake booster.

What is a Vacuum Brake Booster?

A vacuum brake booster is a part of the braking system that uses engine vacuum to assist the driver in applying the brakes with less effort, especially in heavy-duty trucks. Without it, braking would be significantly more difficult and potentially dangerous.

Structure and Operating Principle

A vacuum brake booster is typically round, made of metal or hard plastic, and located in the engine compartment near the brake system. Inside, a diaphragm divides it into two chambers. One chamber is connected to the engine’s vacuum line, while the other is connected to a control valve and the brake pedal.

When the driver presses the brake pedal, the control valve opens, creating a pressure difference between the two chambers. The engine vacuum then acts on the diaphragm, providing significant assistance to make braking easier.

Benefits of Using a Vacuum Brake Booster

• Reduced braking effort: This is the most obvious benefit. The booster significantly reduces the force required to apply the brakes, especially in heavy trucks.
• Enhanced braking efficiency: The booster helps shorten braking distance, improving safety.
• Improved driving comfort: Drivers experience less fatigue from frequent braking, particularly in heavy traffic.

Vacuum Brake Booster Price List

The price of a vacuum brake booster varies depending on the type, brand, and vehicle model. Below is a sample price list:

Precautions When Using a Vacuum Brake Booster

• Regular inspection: Regularly check the booster for leaks or damage.
• Choose quality products: Purchase boosters from reputable brands to avoid counterfeit or low-quality products.
• Proper installation: Installation should be done by experienced technicians to ensure proper operation and safety.
