- Vehicle dynamics during braking are being discussed: Technician A says that the rear of the car rises during braking. Technician B says that the front of the car lowers during braking. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardBesides indicating ABS faults for some systems, the red brake warning lamp on the instrument panel can indicate failure of the brake system, application of the brake, or low fluid level in the.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
- Technician A says that it is normal for the amber brake lamp to light when the ABS is activated during braking. Technician B says that it is normal for the red brake lamp to be on whenever the ignition is on and the engine is off. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardTechnician A says that a malfunction of the ABS causes the control module to shut off or inhibit the system. Technician B says that a loss of hydraulic fluid or power booster pressure disables the antilock brake system. Who is correct? a.

- While road testing a car equipped with an ABS: Technician A says that during heavy braking, several pulses may be felt through the brake pedal. Technician B says that a spongy pedal during normal braking is normal. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardThe purpose of the master cylinder is to. generate the hydraulic pressure needed to apply the brake mechanisms automatically pump the brakes during panic stops apply braking power when wheel slippage occurs all of the abovearrow_forwardTechnician A says that each ABS has its own diagnostic procedure involving use of the brake and antilock warning lamps, special testers, breakout boxes, scan tools, troubleshooting charts, and wiring diagrams. Technician B says that ABSs vary in the number of codes they can store and whether they will retain the code in memory when the ignition is turned off. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forward
- True or False? Disc brakes are not as likely to fade during heavy braking as are drum brakes.arrow_forwardWhen replacing an air bag module: Technician A says that the steering column clockspring should be maintained in its correct index position at all times. Technician B says that failure to keep the clockspring straight ahead or in the neutral position relative to the steering wheel can cause damage to the enclosure, wiring, or module. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardTechnician A says that some traction control systems eliminate wheel spin by applying the brakes on the driving wheels. Technician B says that some traction control systems eliminate wheel spin by retarding ignition timing and cutting off fuel injection. Who is correct?
