Study Notes
Brake Pads
- Made of friction material bonded to a metal backing plate
- Types:
- Organic (semi-metallic): asbestos-free, quieter, but less durable
- Sintered metal: durable, high-temperature resistant, but noisier
- Ceramic: quiet, low dust, good for normal driving conditions
- Functions:
- Convert kinetic energy into heat energy
- Absorb and distribute braking forces
- Provide a smooth, quiet braking experience
Disc Brakes
- Consist of:
- Rotor (disc): attached to wheel hub, rotates with wheel
- Caliper: houses brake pads, slides on rotor to apply pressure
- Brake pads: attached to caliper, contact rotor to slow vehicle
- Advantages:
- Better heat dissipation
- Improved stopping power
- Less prone to brake fade
- Used on:
- Front wheels of most modern vehicles
- High-performance vehicles
Brake Fluid
- Hydraulic fluid that transmits pressure from brake pedal to brake caliper
- Types:
- DOT 3: glycol-based, suitable for most vehicles
- DOT 4: higher boiling point, for high-performance vehicles
- DOT 5.1: silicone-based, for vehicles with silicone-based brake systems
- Properties:
- High boiling point
- Low viscosity
- Corrosion protection
ABS System (Anti-lock Braking System)
- Prevents wheel lock-up during hard braking, maintaining traction and vehicle control
- Components:
- Speed sensors: monitor wheel speed and detect lock-up
- Electronic control unit: processes sensor data, activates solenoids
- Solenoids: rapidly pulse brake pressure to individual wheels
- Benefits:
- Reduced stopping distance
- Improved vehicle stability
- Enhanced safety
Drum Brakes
- Consist of:
- Brake drum: attached to wheel hub, rotates with wheel
- Brake shoes: attached to brake drum, expand to contact drum
- Functions:
- Converting kinetic energy into heat energy
- Slowing or stopping the vehicle
- Used on:
- Rear wheels of some vehicles (e.g., older models, heavy-duty trucks)
- Vehicles with drum brakes in the rear, disc brakes in the front
