Understanding Truck Disc Brakes for Safe Operation

“Screech…” A truck’s brakes abruptly pierced the dense traffic on Nguyen Van Linh Street, Long Bien District, Hanoi. The Hino truck driver from Truong Phat dealership breathed a sigh of relief, his hands still gripping the steering wheel. He had braked just in time, narrowly avoiding a serious accident with a woman carelessly crossing the street. Shaking his head, the driver silently thanked the responsive disc brake system that had averted the dangerous situation.

Indeed, as the truck driver in the story above noted, the disc brake system is the “silent hero” ensuring safety on every journey. But do you truly understand this crucial system in your truck? Let’s delve into the details with Hanoi Trucks!

What Are Truck Disc Brakes? Structure and Working Principle

1. Definition

A disc brake system is a braking system that uses friction between the brake pads and the brake rotor (disc) to slow down or stop a vehicle. This system is commonly used for the front wheels of trucks due to its high braking efficiency and excellent heat dissipation capabilities.

2. Structure

A truck disc brake system typically consists of the following main components:

• Brake Rotor (Disc): Usually made of cast iron or steel, and is fixed to the wheel.
• Brake Pads: Made of high-friction material, these press against the brake rotor when the brakes are applied.
• Brake Caliper: This component houses the hydraulic pistons and brake pads, and its function is to convert hydraulic pressure from the brake fluid into mechanical force to press the brake pads against the rotor.
• Brake Fluid: Transmits pressure from the brake pedal to the wheels.

3. Working Principle

When the brake pedal is pressed, the brake fluid pressure increases and acts on the hydraulic pistons within the brake caliper. The pistons push the brake pads against both sides of the brake rotor, creating friction that reduces the wheel’s rotational speed, thus slowing down or stopping the vehicle.
