6 6 Fuel for Thought How are disc and drum brakes different? How do antilock brakes work? How do you know when brake pads need replacing?

7 7 Objectives Upon completion of this PowerPoint and brake tasks, you will be able to: –Define the purpose and principles of the braking system. –Identify the different types of brakes and their components. –Identify brake fluid properties. –Discuss the advantage of antilock brakes. –Explain how the parking brake works. –Safely perform basic inspections on the braking system.

8 8 Braking System Purpose The braking system is designed to decrease the speed of a vehicle.

19 19 Brake Fluid Links the braking components Fights corrosion, lubricates moving parts, and protects metal, plastic, and rubber components Most common type DOT 3, but always check owner’s manual or cap

20 20 Antilock Brakes An antilock braking system (ABS) minimizes wheel lockup (skidding) by using sensors at each wheel (or in the differential) to monitor wheel speed, a hydraulic unit to regulate brake pressure, and a computer/controller to command the system.

21 21 Electronic Stability Control Electronic stability control (ESC) has been added to many vehicles to help drivers maintain control during unstable situations such as attempting to avoid a crash or during unfavorable weather conditions.

22 Two common issues First issue is a dragging brake. This causes the vehicle to pull to one side. Can be caused but a stuck brake caliper or wheel cylinder. Second Sponge brake. This is caused by air in the hydraulic system. Anytime you open the system it need to be bleed. 22

23 23 Parking Brakes A hand lever in the center of the console or small foot pedal on the far left side of the driver’s foot controls engages the cable. The mechanical cable allows the systems to work independently of each other.

25 25 Summary Brake systems use friction to slow and stop a vehicle. The two types of brake systems used today are disc and drum brakes. Disc brakes use rotors, pads, and calipers. Drum brakes use drums, shoes, and wheel cylinders. Antilock brakes assist in preventing wheel lockup and provide the operator with maximum directional control.
