2 Technician A says that excessive pedal travel can be caused by low brake fluid levels. Technician B says that excessive pedal travel can be caused by air in the hydraulic system The brakes of a car tend to drag, which of the following could be the cause When repairing a damaged brake line which of the following is correct Technician A says that brake drums should never be machined beyond the maximum diameter designed on the drum Technician B says that the brake drum with more than 0.00 inch out of roundness should be machined true on a lathe Who is right: A customer complains that the brake pedal slowly moves to the floor when a steady pressure is applied. There is no sign of fluid leakage. Which of the following is the most probable cause of the problem? A car has an excessive amount of pedal travel during brake application. Which of the following should be the cause? Technician A says it is not normal for brake shoes to have excessive wear in the center of the shoe. Technician B says if the lining is less than? of an inch above the rivets it should be replaced. Who is correct? A car has a spongy pedal. Which of the following could be the cause? All of the following except one could cause the parking brakes to fail or not hold All of the following are in the procedure for servicing a typical duel master cylinder, except: All of the following procedures, except one describe the Correct method of bleeding individual brakes on a car after the master cylinder has been bled: A car equipped with a vacuum assist power brake system needs an abnormal amount of pedal effort to stop the car, Which of the following could be the cause?

3 The brakes of a car chatter when they are applied. Which of the following could cause this problem? Technician A says the dust boot of a caliper should be removed and a large screwdriver used to pry the piston out of it's bore. Technician B says air pressure should be injected into the brake line hole to force the piston out of the brake caliper. The brake warning light on the dash stays on all the time. Which of the following could be the cause of the problem? The front of the car equipped with disc brakes in the front and drum brakes in the rear, grab quickly as light pressure is applied to the brake pedal, which of the following could be the cause of the problem? A car's wheel severely vibrates when the brakes are applied. Which of the following is the LEAST likely source of the problem? The brakes of a car squeal each time they are applied. Which of the following is the LEAST likely source of the noise? The brake lights on a car do not light when the brake pedal is depressed. Which of the following is the LEAST likely cause of the problem? To remove air from the brake line you must: Which is not a part of the disc brake system? Which is not a part of the drum brake system? The emergency brake works on the: A wheel cylinder is found on: When the piston moves from the top of the cylinder to the bottom of the cylinder which of the following has occurred The pistons reciprocating motion is turned into rotary motion by the Pascal s Law is about: The rear piston assembly of a master cylinder is the: Which of the following could cause a trouble code for one of the wheel speed sensors? The engine oil level is checked with

4 Why does a master cylinder have two pistons? Oil filters should be tightened What kind of brake fluid does the typical car use Which shoe is larger? A customer complains of a grinding nose in the front right wheel when the brakes are applied. What is the possible cause? If brake pads are shinny they are The intake valve is open on the: The exhaust valve is open on the: On the intake stroke the piston is going: On the power stroke the piston is going: On the exhaust stroke the piston is going: On the compression stroke the piston is going: Intake and exhaust valves in an automobile gasoline engine are held closed by: An engine is found to be missing on one cylinder. Of the following, what is the most likely cause? Technician A says that pulling on the cable of a spark plug can break the conductive material. Technician B says that the fluid leaks such as oil and gasoline can cause spark plug wire insulation to break down.

5 The oil warning lamp lights whenever the car goes over a bump. Which of these is most likely the cause of the problem? The exhaust coming from a vehicle is black. What is the most likely cause?
