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
