The brake pads of construction vehicles (such as trucks, excavators, loaders, etc.) differ significantly from those of passenger cars in terms of materials, structure, and usage environment. Their design focuses more on high strength, high temperature resistance, long service life, and adaptability to extreme working conditions. The following is an analysis of the main advantages and characteristics of engineering vehicle brake pads:

1. Strong and super high temperature resistance (resistance to thermal degradation)
High temperature stability:
Engineering vehicles have a relatively large weight (such as heavy-duty trucks that can reach over 50 tons when fully loaded), and the friction surface temperature during braking can reach 600-800 ℃, far exceeding that of passenger cars (usually 300-500 ℃).
Using high carbon/metal sintered materials or ceramic composite formulas to ensure that the friction coefficient does not decay at high temperatures (avoiding brake failure caused by "thermal decay").
Continuous braking capability:
Suitable for long downhill slopes, mines and other scenarios, such as trucks in Yungui mountainous areas that require long-term braking, ordinary brake pads are prone to failure, while engineering vehicle specific brake pads can maintain stable performance.
Typical technology:
Copper based/iron-based sintered materials (such as the engineering brake pads of TMD in Germany).
Ceramic reinforcement formula (used for mining vehicles to reduce thermal cracking).
2. High wear resistance and longer lifespan
Low wear rate:
The thickness of brake pads for construction vehicles is usually 2-3 times that of passenger cars (such as truck brake pads with a thickness of 30-40 mm), and the service life can reach 100000 to 200000 kilometers (passenger cars usually have a thickness of 30000 to 50000 kilometers).
Add wear-resistant components such as steel fibers, graphite, and silicon carbide to the material to reduce frequent replacement.
Adapt to harsh environments:
There is a lot of dust and sediment in mining and construction sites, and brake pads need to be corrosion-resistant and resistant to particle wear.
Comparative data:
Vehicle brake pad lifespan (10000 kilometers) Typical materials
Passenger cars (sedans) 3-5 semi metal/ceramic
Engineering vehicle (truck) 10-20 sintered metal/high carbon composite
3. Braking reliability under extreme loads
High friction coefficient (0.4~0.5):
The friction coefficient of passenger car brake pads is usually 0.35~0.45, while construction vehicles require higher braking force, especially under heavy loads and slippery roads.
Compression and impact resistance:
The brake pad back plate of the engineering vehicle is made of thickened steel plate or forged process to avoid deformation or cracking during heavy load braking.
Application scenarios:
Port trailer: Frequent start stop, requiring instantaneous high braking force.
Mining dump truck: with a load capacity of over 100 tons, the brake pads need to withstand huge inertial forces.
4. Adapt to complex environments (dustproof, waterproof, corrosion-resistant)
Rust prevention treatment:
Surface coating or special coating (such as zinc nickel alloy) to prevent corrosion from rainwater and melting salts.
Chip removal design:
The groove or perforated structure helps to discharge sediment and metal shavings, avoiding brake noise and uneven wear.
Typical case:
The brake pads of engineering vehicles in the Nordic region need to adapt to low temperatures of -30 ℃, and the materials need to maintain flexibility.
Brake pads in desert mining areas need to prevent sand particles from invading.
5. Customized design (matching different engineering vehicle models)
Adaptation by vehicle model:
The braking systems of excavators, loaders, and heavy-duty trucks vary greatly, and brake pads need to be designed specifically (such as wet brake pads commonly used in excavators).
Special requirements solution:
Fire truck/military vehicle: resistant to extreme temperatures (-50 ℃~1000 ℃).
Electric engineering machinery: energy recovery braking+friction braking coordinated optimization.
6. Stricter regulations and safety certifications
Industry standards:
Must comply with ISO 7881 (Commercial Vehicle Brake Standard), GB 5763-2018 (Compulsory Standard for Commercial Vehicle Brake Pads in China), etc.
OEM certification:
Volvo, Mercedes Benz and other commercial vehicles have separate certification for brake pads (such as WABCO certification).
7. Representing brands and products
