Heavy-duty brake pads are critical components for commercial vehicles(trucks,buses,heavy-duty trucks,etc.)with the following characteristics:
High Wear Resistance:Designed to withstand extreme friction from heavy loads,ensuring prolonged service life and reduced replacement frequency.
Exceptional Heat Resistance:Capable of maintaining optimal performance under intense heat(up to 600-800°C)to prevent brake fade during prolonged braking.
Superior Braking Force:Engineered with high-friction materials(μ0.40-0.50)to ensure effective stopping power for fully loaded vehicles.
Stable Performance:Delivers consistent braking across various speeds,loads,and road conditions.
Material Composition
Base Material:High-strength steel or cast iron backing plates for structural integrity
Friction Material:Advanced composite containing:
Thermoset resins(phenolic modified)
Reinforcing fibers(aramid/ceramic)
Friction modifiers(graphite/molybdenum disulfide)
Performance fillers(alumina/barites)
Product Types
Drum Brake Linings:
Curved design for drum contact surface
Cost-effective solution for standard applications
Typical thickness:10-12mm(replace at≤3mm)
Disc Brake Pads:
Flat plate design with chamfered edges
Superior heat dissipation(ventilated rotors)
Common sizes:160×80×20mm(varies by vehicle)
Maintenance Protocol
Inspection Interval:
Standard:Every 15,000-20,000 km
Severe duty:Every 5,000-10,000 km
Replacement Criteria:
Wear limit:2mm remaining thickness
Visual defects:Cracking/glazing/uneven wear
Performance issues:Increased stopping distance
Selection Guidelines
Always verify OEM specifications(e.g.,WABCO/Meritor part numbers)
Match friction grade to vehicle GVWR(Gross Vehicle Weight Rating)
