Brakes quizes

Materials that maintain a stable friction coefficient over a wide temperature range generally require _____ pedal pressures to provide efficient braking.

• Higher

• Lower

• Equalized

• Variable

Tech A says that the brake pedal uses leverage to multiply foot pressure. Tech B says that when braking hard while moving forward, the vehicle's weight transfers to the rear wheels, increasing their traction. Who is correct?

• Tech A

• Tech B

• Both A and B

• Neither A nor B

All of the following can cause brake system dragging, EXCEPT:

• stuck caliper piston.

• misadjusted master cylinder pushrod length.

• restricted brake line or hose.

• Coefficient

• Magnitude

• Velocity

• Gradient

Technician A states that in the Traction Control System, the control unit can independently apply individual brake units even though the driver is not stepping down on the brake pedal. Technician B states that this function can also be carried out by the driver in manual mode. Who is correct?

• Technician A

• Technician B

• Both A and B

• Neither A nor B
