Drum Brake Linings(Brake Drums)

Brake Drums  are the core friction components of drum brake systems,primarily used in commercial vehicles(such as trucks and buses),some passenger vehicles,and construction machinery.They generate braking force by friction against the inner wall of the brake drum,converting the vehicle's kinetic energy into heat to achieve deceleration or stopping.

1.Basic Structure

Drum brake linings typically consist of the following parts:

Friction Material Layer:Made of high-temperature-resistant composite materials,it directly contacts the brake drum to generate friction.

Backing Plate(Steel Base Plate):Supports the friction material and provides structural strength.

Rivets or Adhesive Layer:Secures the friction material to the backing plate.

2.Main Types(By Material Classification)

(1)Asbestos-Based Drum Linings(Gradually Phased Out)

Composition:Asbestos fibers+resin/rubber.

Characteristics:Low cost,but asbestos is carcinogenic and has been banned in most countries.

(2)Semi-Metallic Drum Linings(Mainstream Type)

Composition:Metal fibers(steel,copper)+graphite/ceramic particles.

Characteristics:High-temperature resistance(300~500°C),wear-resistant,but prone to braking noise and higher wear on the brake drum.

(3)Non-Asbestos Organic(NAO)Drum Linings

Composition:Aramid/glass fibers+resin/rubber.

Characteristics:Eco-friendly,low noise,but weaker high-temperature performance;mostly used in light-duty vehicles.

(4)Ceramic Composite Drum Linings

Composition:Ceramic fibers+metal powders.

Characteristics:High-temperature resistance(600°C+),long lifespan,but costly;mainly used in high-performance vehicles.

3.Key Performance Indicators

Friction Coefficient:0.35~0.45(must remain stable at different temperatures).

Wear Rate:≤0.1 cm3/MJ(wear per unit energy).

Heat Fade Resistance:Friction coefficient decline at high temperatures should be<20%.

Noise Level:Must pass NVH(Noise,Vibration,Harshness)testing.

4.Applications

Commercial Vehicles:Trucks,buses(due to strong braking force and low heat dissipation requirements).

Construction Machinery:Excavators,loaders(resistant to mud,water,and dust).

Some Passenger Vehicles:Budget car rear-wheel braking(low cost).
