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 |
|
provides higher hydraulic pressure in the braking system |
|
utilizes battery power to assist in braking |
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.
The __________ converts pressure on the brake pedal to hydraulic pressure in the brake lines.
master cylinder |
|
brake linkage |
|
brake knuckle |
|
brake cylinder |
The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines.
What is the large casing that contains the cylinders and many of the internal components of the engine?
engine block |
|
manifold |
|
chassis |
|
transmission |
The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.
