Technician A says that in a traction control system, the control unit can independently apply individual brake units even though the driver is not stepping on the brake pedal. Technician B says that a vehicle equipped with ABS can automatically reduce engine torque if the wheels are skidding. Who is correct?
Technician A
Technician B
Both Technician A and Technician B
Neither Technician A nor Technician B
______ gives greater control of the braking system to the computer, which can react more quickly and more deliberately than a driver, especially in a panic situation.
Disc brake
Band brake
Scrub brake
Brake assist
Scrub brakes are an example of a simple ________ system.
Hydraulic
Pneumatic
Mechanical
Electrical
Identify the brake system that uses a metal band lined with friction material.
Scrub brake
Band brake
Hydraulic brake
Drum brake
Tech A states that the band brake system worked well in the reverse direction. Tech B states that the band would try to unwind in the forward direction. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
Tech A states that too much brake force can cause the tire to lose traction and skid. Tech B states that ABS systems have helped to reduce the number of vehicle accidents each year. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
Tech A says that the brake pedal uses leverage to multiply foot pressure. Tech B says that when braking hard while moving forward, the vehicle's weight transfers to the rear wheels, increasing their traction. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
Tech A says that light-duty service brakes are typically applied hydraulically. Tech B says that light-duty parking brakes are typically applied hydraulically. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
Tech A states that designers can vary the size of hydraulic cylinders to increase or decrease the force applied by a brake. Tech B states that the hydraulic cylinders of a brake system must always be of the same size. Who is correct?
Tech A
Tech B
Both Tech A and B
Neither A nor B
If we triple the speed of an object, the kinetic energy will:
increase by three times.
increase by nine times.
decrease by three times.
decrease by six times.
Static friction is resistance between nonmoving surfaces and is present in which type of brakes?
Parking
Standard
Both parking and standard
All types
Technician A states that in the Traction Control System, the control unit can independently apply individual brake units even though the driver is not stepping down on the brake pedal. Technician B states that this function can also be carried out by the driver in manual mode. Who is correct?
Technician A
Technician B
Both A and B
Neither A nor B
The ______ tells the computer how firmly the driver intends to brake.
Brake-by-wire system
Anti-lock brake system
Brake pedal emulator
Brake assist
Which of the following is MOST likely to be a parking brake system on a vehicle?
Top hat drum style
Electric pull-cable style
Electric motor caliper style
All of the above
Parking brake cables transmit force from the parking brake actuating lever to the ________.
Return spring
Adjuster
Brake unit
Reactor spring
The air pressure for air brake systems comes from an engine-driven air compressor that pumps air into storage tanks.
True
False
A(n) ________ brake (or compression brake) uses an extra lobe on the camshaft to control an auxiliary exhaust valve at the top of each cylinder.
Electric
Parking
Air
Jake
Trailers must be able to be hooked up to multiple tow vehicles, therefore, connecting a hydraulic brake system to each tow vehicle becomes difficult. Tech A states that this is because of the leaking of hydraulic fluid. Tech B states that this is because of the air entering the lines. Who is correct?
Tech A
Tech B
Both A and B
Neither A nor B
All of the following are benefits to brake-by-wire systems, EXCEPT:
weight is reduced and space is saved.
drivers do not feel ABS brake pulsations.
brakes are applied more quickly in an emergency situation.
initial cost.
Tractor-trailers achieve minimized brake application by using which of the following?
Relay valve
Separate air tank on the trailer
Both A and B
None of the above
