DongFeng Disc Brake Friction Plate YF3502DR01-040

The DongFeng Disc Brake Friction Plate YF3502DR01-040 is a heavy-duty friction component used in the disc brake system of commercial vehicles and trucks. It is designed to provide the friction required for effective braking and plays an important role in converting the vehicle’s kinetic energy into braking force.

The YF3502DR01-040 part number is associated with truck disc brake friction plates and brake pads. Available parts catalogs identify this reference with heavy-duty truck brake applications, including DongFeng-related applications. Some catalogs list dimensions of approximately 248 × 109 × 29.8 mm for this reference.

Sogin Parts specializes in supplying DongFeng and Cummins spare parts, including engine, drivetrain, chassis and brake system components for commercial vehicles.

Product Overview

The YF3502DR01-040 Disc Brake Friction Plate is a friction material component installed in a disc brake assembly.

When the brake system is activated, the friction material is pressed against the rotating brake disc. The resulting friction slows down the disc and reduces the vehicle’s speed.

In simple terms:

Brake Pad / Friction Plate → Brake Disc → Friction → Braking Force

Because this component is directly involved in the braking process, its quality, dimensions and compatibility with the brake assembly are extremely important.

What Is a Disc Brake Friction Plate?

A Disc Brake Friction Plate is the friction component of a disc brake system.

Unlike a brake disc, which rotates with the wheel assembly, the friction plate or brake pad is part of the braking mechanism that applies friction to the rotating disc.

When the driver presses the brake pedal:

1. Hydraulic or pneumatic pressure activates the brake mechanism.
2. The brake pad moves toward the brake disc.
3. The friction material contacts the rotating disc.
4. Friction is generated.
5. The rotation of the wheel is reduced.
6. The vehicle slows down or stops.

For heavy-duty commercial vehicles, brake components must withstand repeated braking cycles, high temperatures and significant mechanical loads.

Function of YF3502DR01-040

The main function of the YF3502DR01-040 Disc Brake Friction Plate is to generate controlled friction against the brake disc.

Its performance can directly affect:

• Braking efficiency
• Brake response
• Heat generation
• Brake system stability
• Brake component wear
• Vehicle safety

For heavy trucks, proper brake component selection is particularly important because the vehicle operates with considerably higher loads than passenger cars.

YF3502DR01-040 Brake Pad Application

The part number YF3502DR01-040 appears in multiple heavy-duty truck brake parts catalogs as a disc brake friction plate / brake pad reference. One catalog associates the reference with DongFeng Tianlong and related heavy-duty truck applications, while other commercial parts listings also identify it as a front disc brake friction component.

Because different truck configurations can use similar brake components, customers should always verify the exact application before purchasing.

Signs of a Worn Disc Brake Friction Plate

Brake friction material is a wear component and must be inspected periodically.

Possible signs of excessive brake pad or friction plate wear include:

Reduced Braking Performance

If the vehicle requires more braking distance or the brake response becomes weaker, the brake system should be inspected immediately.

Unusual Brake Noise

Grinding, squealing or abnormal sounds may indicate excessive wear or another brake-system problem.

Uneven Brake Wear

Uneven wear can indicate problems with the brake caliper, disc, installation or other components.

Excessive Brake Dust

An unusual increase in brake dust may indicate accelerated friction material wear, although dust levels can vary depending on the friction material and operating conditions.

Brake Disc Damage

A severely worn friction plate can allow the backing material to contact the brake disc, potentially causing expensive damage to the disc.

Why Quality Matters

The brake system is one of the most safety-critical systems in a commercial vehicle.

A suitable friction plate should provide stable friction performance across a wide range of operating temperatures and braking conditions.

Poor-quality or incorrectly specified brake components may result in:

• Reduced braking efficiency
• Uneven braking
• Excessive brake noise
• Premature wear
• Brake disc damage
• Excessive heat
• Increased maintenance costs

For this reason, the correct Part Number, dimensions and application should be confirmed before installation.
