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.
Written by Donald P. Hessenaur As aircraft engine prices continue to rise beyond the reach of most who would like to build and fly their own aircraft, many are turning to alternate power sources. This is not a new phenomenon. From the Wright brothers on, many have designed, built or converted engines to aircraft use. At one time or another engines have been used from automobiles, motorcycles, outboard motors and even snowmobiles, with varying degrees of success or failure. AUTO ENGINE CONVERSIONS Today many automotive engine conversions are appearing on the aviation scene. They are definitely a viable alternative. The automotive engine today is very advanced technically and relatively low in cost when compared to Lycomings and/or Continentals. Unfortunately, automotive engines are designed and optimized for the automobile and not for aircraft. Generally auto engines operate at a much higher RPM. The torsional vibration characteristics of a given engine, connected to a transmission, drive train and wheels, are quite different from that of the same engine, connected to an aircraft propeller. The damping action of the tires on the road and the inertia effects of the mass of the automobile are not even close to the damping/inertia effects of a propeller turning in air.
Eaton’s Driveline Angle Analyzer Tool Kit (DAA 2) Helps Eliminate Torsional Vibration Problems The tool kit diagnoses the driveline angles that cause torsional vibrations between the transmission and front and rear drive axles. Varying ride heights, angles and configurations can create torsional vibrations throughout the drivetrain, which in turn can cause noise complaints and vibrations that result in significantly reduced drivetrain component life. Frequently, vehicles are sensitive to small changes in driveline angles, making it virtually impossible even for a seasoned technician to visually inspect a driveline and see whether its component angles are going to lead to problems down the road. Eaton’s Driveline Angle Analyzer allows you to properly measure driveline angles and diagnose potential problems before serious damage to the equipment occurs. The analyzer also identifies corrections for optimum component life.
– Drivelines and Universal Joints Universal Joint Maintenance • Most factory-installed universal joints are sealed and don’t require periodic lubrication • After-market replacement joints are equipped with a grease fitting and must be greased periodically Drive Shaft Problem Diagnosis • Road testing – Vehicle should be driven while accelerating and decelerating as well as at various steady speeds – Vibrations caused by worn U-joints usually occur while accelerating Types and Causes of Vibrations • High speed vibrations – Usually caused by driveshaft imbalance • Vibrations during acceleration – Usually caused by worn double Cardan joint ball and socket • Low speed vibrations – Usually caused by improper operating angles Noise Diagnosis • Clunking noise while accelerating from a dead stop – Usually caused by worn or damaged U-joint – Can be caused by problems including excessive clearance between slip joint and extension housing • Squeaking noise – Often caused by worn or poorly lubricated U-joint Reasons for Universal Joint Failure • Lack of lubrication • Pushing another car • Towing a trailer • Changing gears abruptly • Carrying heavy loads Steps in Lubricating U-Joints 1. Wipe off the nozzle of the fitting 2. Attach the hose of the grease gun to the fitting 3. Pump grease slowly into the fitting 4. Stop pumping when grease appears at the bearing cups Inspecting the Drive Shaft • Check for fluid leaks • Check the U-joints for signs of rust or leakage • Check for movement in the joint while trying to turn the yoke and the shaft in opposite directions • Check the drive shaft for dents, missing weights, and undercoating or dirt...
