This article describes the working principle of disc brakes. It discusses the different components of a disc brake assembly, the working principle of the disc brake, and the advantages and disadvantages of disc brakes.

Questions

• What are the different components of a disc brake assembly?
• What is the working principle of a disc brake?
• What are the advantages and disadvantages of disc brakes?

Answers

• The different components of a disc brake assembly are the brake pads, caliper bracket, caliper frame, piston, slider pin, and dust boots.
• The working principle of a disc brake is based on Pascal’s law. When the brake pedal is pressed, the high pressure fluid from the master cylinder pushes the piston outward. The piston pushes the brake pad against the rotating disc, which creates friction and slows down the vehicle.
• The advantages of disc brakes are that they are lighter than drum brakes, have better cooling, offer better resistance to fade, provide uniform pressure distribution, and are easy to replace. The disadvantages of disc brakes are that they are more expensive than drum brakes, require higher pedal pressure, and are more difficult to attach a parking attachment to.
