What is the pimary advantage of using power brakes on a vehicle?
requires less brake fluid to operate the braking system |
|
allows the use of antilock brakes |
|
utilizes battery power to assist in braking |
|
provides higher hydraulic pressure in the braking system |
Power brakes multiply the force a driver applies to the brake pedal using a vacuum booster connected to the engine intake manifold. This provides for much higher hydraulic pressure in the braking system than could be generated by the driver alone. Antilock brakes (ABS) use speed sensors and adjust the brake pressure at each wheel to prevent skidding and allow the driver more steering control in slippery conditions.
Power brakes multiply the force a driver applies to the brake pedal using a __________ connected to the engine intake manifold.
cylinder |
|
vacuum booster |
|
brake line |
|
speed sensor |

Control arms connect a vehicle's suspension to the frame. The connection to the frame uses:
knuckles |
|
pins |
|
ball joints |
|
bushings |
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
Which of the following statements about v-type cyllinder arrangement is false?
has an odd number of cylinders |
|
has two rows of cylinders |
|
engine is shorter than an inline engine |
|
common in motorcycles, cars, and trucks |
A v-arrangement has two rows of cylinders in a V-shaped block with a crankshaft at the bottom of the V. Any even number of cylinders is possible in this configuration from the V-2 that's commonly used in motorcycles up to V-12 or bigger for large trucks. The V design produces a shorter engine than an in-line cylinder configuration and allows for better air-fuel distribution.
The __________ provides the appropriate power to vehicle wheels to maintain a given speed.
transaxle |
|
ignition coil |
|
gearbox |
|
transmission |
The transmission provides the appropriate power to vehicle wheels to maintain a given speed. The engine and the transmission have to be disconnected to shift gears and a manual transmission requires the driver to manually manage this disconnection (using a clutch) and to manually shift gears. An automatic transmission is essentially an automatic gear shifter and handles this process without driver input.
