Brakes Test Questions 100% All Solved

Brakes Test Questions 100% All Solved Two technicians are discussing Newton's first law of motion. Technician A says that a lightweight vehicle requires as much energy to accelerate as a heavier vehicle. Technician B says that a lighter vehicle requires less energy to accelerate than a heavier vehicle. Who is correct? - Tech B The parking brake cable pulls on an actuating lever inside the brake drum assembly. - True Tech A states using an air-operated brake on heavy trucks is easier. Tech B states that using a hydraulic brake on a heavy truck is easier. Who is correct? - Tech A Static friction is resistance between nonmoving surfaces and is present in which type of brakes? - Parking brakes Which of the following components is NOT typically found on an electric brake system? - Wheel cylinder Tech A states that the scrub braking system worked well in rubber tires. Tech B states that the scrub braking system worked reasonably well on dry wheel surfaces made of wood or steel. Who is correct? - Tech B 2 | P a g e Author: Katelyn Whitman. ©2025, All Rights Reserved. Skidding tires on the surface of the road (kinetic friction) do not have as much friction as rolling tires, and therefore the stopping distance (blank), which can lead to an accident. - is increased Parking brake cables transmit force from the parking brake actuating lever to the - Brake unit The rotational force found in a braking vehicle tends to - push the nose down and lift the rear A(n) (blank) brake (or compression brake) uses an extra lobe on the camshaft to control an auxiliary exhaust valve at the top of each cylinder. - Jake brake The best example of (blank) is when a motorcycle rider applies the front brake hard enough that the rear wheel is lifted completely off the ground. - rotational force Tech A says that the heavier the vehicle, the more stopping power is needed. Tech B says that the faster a vehicle is moving, the more braking power is needed. Who is correct? - Both A and B Some foot-mounted parking brake levers can be released by pulling a release handle, which retracts the ratcheting tang and allows the pedal to return to its rest position. - True Tech A says that disc brakes were originally developed in the early 1900's but didn't find common use until the 1960's. Technician B says that a disc brake operates by 3 | P a g e Author: Katelyn Whitman. ©2025, All Rights Reserved. squeezing brake pads on both sides of a rotor or disc that is sttached to the wheel. who is correct? - Both A and B All the following are disadvantages to a jake brake except - increases brake effectiveness In regenerative braking, the amount of stopping power is controlled by the amount of - electricity generated For hydraulic cylinders of the same size, the (blank) transmitted from one is the same value as the (blank) applied to the other. - force, force A substantial leak in the (blank) will prevent enough pressure from building to exert the necessary braking force - hydraulic system Technician A says that the brake calipers use hydraulic pressure from the master cylinder to apply the brake pads. Technician B says that when the brake pedal is depressed, a push rod transfers force through a brake b
