Introduction Everybody knows that when you press your foot on the brake pedal the vehicle is supposed to stop. But how does the pressure from your foot get to the wheels with enough force to stop a heavy vehicle? In the following sections, we will study the systems and components required to allow brakes to work effectively. Course Objectives Upon completion of this course, technicians should understand and be able to apply their knowledge of: • • • • • • • • • • • • Brake functions and components Split hydraulic systems Master cylinder operations Balance control systems Power brake booster systems Disc brake operation Micrometer reading Drum brake operation Brake fluids Brake bleeding operations Brake lines and hoses Basic diagnosis Using the Job Sheets As you proceed through the online module, on some pages you will find links that will open a window with a printable procedure or job sheet containing hands-on lab activities based on the NATEF standards related to the content you are studying. When you come upon a procedure or job sheet link, click on it and print the job sheet for completion in the shop. See your instructor for guidance in completing the job sheets. Some jobs sheets will require supplemental materials such as a vehicle service manual, equipment manual, or other references. Brake System Functions Automotive brakes are designed to slow and stop a vehicle by transforming kinetic (motion) energy into heat energy. As the brake linings contact the drums/rotors they create friction which produces the heat energy. The intensity of the heat is proportional to the vehicle speed, the weight of the vehicle, and the quickness of the stop. Faster speeds, heavier vehicles, and quicker stops equal more heat. Automotive brake systems can be broken down into several different sub-systems (fig. 1): • Apply system • Boost system • Hydraulic system • Wheel brakes • Balance control system • Warning system (fig. 1) Base Brake Systems .
GENERAL PROCEDURES Driveshaft Runout and Balancing Special Tool(s) Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) or equivalent Mastertech® Series MTS 4000 Driveline Balance and NVH Analyzer (Vetronix) 257-00018 or equivalent Driveshaft Inspection NOTE: Driveline vibration exhibits a higher frequency and lower amplitude than high-speed shake. Driveline vibration is directly related to the speed of the vehicle and is noticed at various speeds. Driveline vibration can be perceived as a tremor in the floorpan or heard as a rumble, hum or boom. NOTE: Refer to Specifications in this section for all runout specifications. 1. NOTE: Do not make any adjustments before carrying out a road test. Do not change the tire pressure or the vehicle load. Carry out a visual inspection of the vehicle. Operate the vehicle and verify the condition by reproducing it during the road test. • 2. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02. • 3. The concern should be directly related to vehicle road speed, not affected by acceleration or deceleration or could not be reduced by coasting in NEUTRAL. The driveshaft should be kept at an angle equal to or close to the curb-weighted position. Use a twin-post hoist or a frame hoist with jackstands. Inspect the driveshaft for damage, undercoating or incorrectly seated U-joints. Rotate the driveshaft slowly by hand and feel for binding or end play in the U-joint trunnions. Remove the driveshaft. For additional information, refer to Section 205-01. Inspect the slip yoke splines for any galling, dirt, rust or incorrect lubrication. Clean the driveshaft or install new U-joints as necessary. Install a new driveshaft if damaged. After any corrections or new components are installed, recheck for the vibration at the road test speed.

W hile many people agree that a roaring fire on a cold day helps make a house a home, choosing from today’s myriad of hearth options can be confusing, especially when trying to balance aesthetics with efficiency. From style to fuel type and heating needs to installation restrictions, there is a fireplace, stove, insert or log set that is right for you and your house. Traditional fireplaces provide the ambiance of a roaring fire, but send most of their heat and all of the combustion by-products up the chimney. Today’s consumers not only demand ambiance, but also want to capture the heat while reducing the environmental impact. Manufacturers have responded with attractive fireplaces, stoves and other options that warm the living areas of your home while saving you money on your heating bill. Enjoying a fire can be as simple as pushing a button or as engaging as cutting your own wood, building and tending a fire. Your local hearth retailer can help determine the best product based on climate, lifestyle and your home’s layout. Did You Know? Zone heating (putting heat where you need it, when you need it) allows you to turn down the thermostat on your central heating system, and save money on your energy bill.
