System Parts第 14 / 60 题
What is the function of the brake chamber and pushrod?
a.To store reserve air for the trailer
b.To cool the brake drums during long stops
c.To warn the driver of low air pressure
d.To convert air pressure into mechanical force that turns the slack adjuster
解析
When you brake, air enters the brake chamber and pushes the pushrod outward. The pushrod moves the slack adjuster, which rotates the S-cam and applies the brakes. This converts the air pressure into the mechanical force that presses the shoes against the drum.
