Question

Front brake limiting valves are found on:

a. Older vehicles made before 1975.
b. New 'Import vehicles only.
c. School buses.

Answer 1

Front brake limiting valves are usually found on older vehicles made before 1975, and not on new import vehicles or school buses. Modern brake systems include a motorized pump that assists in braking.

Step-by-step explanation:

Front brake limiting valves are typically found on older vehicles made before 1975. They are not commonly used on new 'Import vehicles' or specifically on school buses. Brake systems on various vehicles, including those with power brakes and machinery like bulldozers, often incorporate a motorized pump. This pump does most of the work in the brake system, providing the necessary force to engage the brakes effectively.
