Q2. What is the working principle of a brake system ?
Ans. 
A brake system works by converting kinetic energy into heat energy through friction to slow down or stop a vehicle.
• Brake pedal is pressed by the driver

• Brake fluid is compressed in the master cylinder

• Pressure is transmitted through brake lines to the brake calipers or wheel cylinders

• Brake pads or shoes press against the brake rotor or drum to create friction and slow down the vehicle
