What are the two major categories of brake systems?
1. Service Brakes (Primary Brakes)Purpose: Used for normal deceleration while driving.How They Work: Activated by the brake pedal, these brakes convert kinetic energy into heat via friction.
Types:Disc Brakes: Use calipers to squeeze pads against a rotor (common in modern cars).Drum Brakes: Use shoes that press outward against a drum (often in rear wheels of budget cars).Pneumatic Brakes: Use compressed air (heavy trucks/buses).Regenerative Brakes: Recover energy in EVs/hybrids.
2. Parking Brakes (Secondary/Emergency Brakes)Purpose: Prevent a parked vehicle from rolling; act as a backup if primary brakes fail.How They Work: Mechanically or electronically engage separate brake components.Types:Manual (Handbrake): Lever or pedal (e.g., traditional handbrake).Electronic (EPB): Button-activated (common in newer vehicles).
