A Roadside Story

The other day, a friend of mine was driving his Dongfeng truck from Bac Ninh to Hanoi. While cruising on Vo Chi Cong Street, his brakes suddenly locked up, nearly causing a collision with the car in front. Luckily, the road was clear, and he managed to react in time. It turned out that the truck’s vacuum pump had malfunctioned, disabling the brake booster system. He had to call for a tow truck and spent the entire afternoon at a repair shop on Nguyen Van Linh Street. From that experience, he learned a valuable lesson: regularly inspect and maintain the vacuum pump in his truck.

What is a Vacuum Pump in a Truck?

A vacuum pump, also known as a vacuum booster pump, is a crucial component in a vehicle’s braking system, especially in heavy-duty trucks. Its primary function is to create negative pressure (vacuum) to assist the braking system in operating more effectively.

The Role of the Vacuum Pump

Brake Assist: The vacuum pump generates vacuum pressure to assist the brake booster. When the brake pedal is pressed, this vacuum is utilized to create force on the booster’s piston, amplifying braking force and making it easier to stop the vehicle, especially at high speeds or when carrying heavy loads.
Reduced Pedal Effort: Thanks to the vacuum pump’s assistance, less force is required to apply the brakes. This makes braking smoother and more comfortable, reducing driver fatigue on long journeys.

Signs of a Faulty Vacuum Pump

Stiff Brakes: This is the most common symptom of a vacuum pump issue. The brake pedal will feel harder than usual, requiring more effort to apply the brakes.
Unusual Engine Noise: A malfunctioning vacuum pump can produce strange noises, such as hissing or whistling, emanating from the engine compartment.
Check Engine Light: In some cases, a serious vacuum pump problem can trigger the check engine light on the dashboard.

Important Note

If you notice any of the above signs, promptly take your vehicle to a reputable garage like Thai Phong Auto on Nguyen Trai Street, Thanh Xuan, or authorized Hyundai or Hino truck dealerships on Giai Phong Street for inspection and repair.
