- While discussing quick take-up master cylinders: Technician A says that this design allows for increased braking power. Technician B says that this design is only used on drum brake systems. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardTrue or False? Disc brakes are not as likely to fade during heavy braking as are drum brakes.arrow_forwardWhile discussing pull during braking: Technician A says that this can be caused by one tire being underinflated. Technician B says that a frozen wheel cylinder on one side of the car can cause this. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forward
- While discussing what affects the amount of pressure exerted by the brakes: Technician A says that the shorter the line, the more pressure there will be. Technician B says that braking force will increase if the size of the pistons in a master cylinder are increased. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardTechnician A says that the master cylinder should be bled before any individual wheel assembly. Technician B says that the bleeder screw should be closed before the brake pedal is released during manual bleeding of the system. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhich of the following is a true statement? In some antilock brake systems, the power brake assist is provided by pressurized brake fluid supplied by the hydraulic accumulator. The accumulator is a small, sealed chamber mounted to the pump/motor assembly. The accumulator holds a highly pressurized nitrogen gas that is used to generate a charging pressure. All of the statements are true.arrow_forward
- Explain how drum brakes create a self-multiplying brake force.arrow_forwardTrue or False? Both the clutch and the brake system may share the same master cylinder.arrow_forwardTechnician A says that some antilock brake systems use a lateral acceleration sensor in addition to the wheel-speed sensors. Technician B says that traction control systems apply one wheel brake to get the vehicle going in the direction in which it is being steered. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forward
- True or False? If brake fluid is dark or brown colored. the system must be flushed and the fluid replaced.arrow_forwardTechnician A says that fixed calipers use a piston on each side of the rotor to apply the brakes. Technician B says that sliding calipers typically use only one piston or pistons on one side of the rotor. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhile discussing the effects of overtorquing wheel lugs: Technician A says that this can cause the threads of the lugs and/or studs to distort. Technician B says that this can cause disc brake rotor distortion. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
