1. What Are Brake Pads and Shoes?
Brake pads and shoes are essential components of a vehicle’s braking system. Brake pads are used in disc brake systems, while brake shoes are used in drum brake systems. Both components create friction against a rotating surface (rotor or drum) to slow down or stop the vehicle.
- Brake Pads: These are flat, rectangular blocks made of friction material. They are pressed against the brake rotor by the caliper when the brake pedal is applied.
- Brake Shoes: These are curved pieces of metal with friction material bonded to them. They press against the inside of the brake drum to create friction.
2. Factors Affecting Brake Pad Lifespan
Several factors influence how long your brake pads will last. Understanding these can help you anticipate when a replacement might be necessary:
- Driving Habits: Aggressive driving, frequent hard braking, and stop-and-go traffic can significantly reduce brake pad life.
- Environment: City driving, with its constant braking, wears pads faster than highway driving.
- Brake Pad Material: Different materials (organic, ceramic, metallic) have varying lifespans.
- Vehicle Type: Heavier vehicles typically require more braking force, leading to quicker wear.
- Quality of Brake Pads: High-quality pads generally last longer than cheaper alternatives.
