System Parts第 9 / 60 题
Why do heavy vehicles use a dual air brake system?
a.To make the brakes work with less pressure
b.To eliminate the need for spring brakes
c.So that if one system leaks, the other can still stop the vehicle
d.To allow the compressor to run continuously
解析
A dual air brake system has two separate air brake systems that use a single set of controls. If one system loses air, the other system can still provide braking to stop the vehicle. Each system typically operates different brakes, giving redundancy for safety.
