Air Break Practice Test

Results

#1. When using the applied stroke method to check pushrod stroke, how much pressure should you apply to the service brakes?

80 – 90 psi

60 – 80 psi

100 – 125 psi

90 – 100 psi

After noting where the pushrod currently is with the service brakes released, apply 620 – 690 kPa (90 – 100 psi) of air pressure to the service brakes and measure how far the pushrod moves (this distance is called the applied stroke). This procedure will probably require two people: one to apply the brakes and one to measure pushrod travel.
