Superior Construction Materials
Manufactured from high-grade HT250 gray cast iron, this brake drum rotor offers exceptional:
Heat resistance (withstands temperatures up to 650°F)
Wear resistance (minimum hardness of 180 Brinell)
Structural integrity (tensile strength of 250 MPa)
Performance Advantages
The 43512-3020 braking component provides:
Consistent friction surface for reliable stopping power
Optimal heat dissipation through precision-engineered cooling fins
Extended service life (typically 80,000-120,000 miles under normal conditions)
Vibration resistance to prevent brake judder
Working Principle
Activation: When brake pedal is depressed, hydraulic pressure engages brake shoes
Friction: Brake lining presses against inner drum surface (friction coefficient: 0.35-0.42)
Deceleration: Kinetic energy converts to heat energy through friction
Dissipation: Heat transfers through drum’s mass and cooling fins
Release: Springs retract shoes when pedal pressure is released
