Heavy-Duty Brake Pads Technical Overview

Features&Requirements

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)

Consider operating environment(mountainous/urban/off-road)

Technical Note:Modern heavy-duty pads incorporate:

Wear sensors with CAN bus integration

Asbestos-free formulations meeting EU Regulation No 305/2011

Laser-etched thermal indicators for overheating warning

Proper installation requires:

Complete brake system inspection

Rotor/drum resurfacing(if applicable)

Proper bedding-in procedure(300-500 km break-in)

For optimal performance,always use manufacturer-recommended brake fluids(DOT 4+/DOT 5.1)and follow prescribed maintenance schedules.
