Question

When measuring the applied push-rod stroke on brakes having exposed push-rods, air pressure must be between:

a) 690 and 828 kPa (100 and 120 psi).
b) 621 and 690 kPa (90 and 100 psi).
c) 690 and 932 kPa ( 100 and 135 psi).
d) 414 and 828 kPa ( 60 and 120 psi).

Answer 1

When measuring the applied push-rod stroke on brakes having exposed push-rods, air pressure must be between a) 690 and 828 kPa (100 and 120 psi) (option a)

Step-by-step explanation:

When measuring the applied push-rod stroke on brakes with exposed push-rods, it is crucial to ensure that the air pressure falls within the specified range. The correct range is between 690 and 828 kPa (100 and 120 psi). This range is determined based on the optimal conditions for accurately measuring the push-rod stroke, which is essential for proper brake functioning and vehicle safety.

Ensuring the correct air pressure is vital because it affects the responsiveness of the brake system. Too low or too high air pressure can lead to inaccurate measurements and compromise the effectiveness of the brake system. Brake adjustments and maintenance are often performed within this specified pressure range to guarantee reliable and consistent performance.

In summary, maintaining air pressure between 690 and 828 kPa (100 and 120 psi) is essential when measuring the applied push-rod stroke on brakes with exposed push-rods, contributing to the overall safety and functionality of the braking system. (option a)
