Chapter 110 ABS Components and Operation

The maximum traction between a tire and the road occurs when the tire is ________.

Antilock brakes cannot defy the laws of physics under what conditions?

Technician A says that the ABS system may not result in shorter stopping distance compared to brakes without ABS. Technician B says that a pulsating brake pedal during normal braking is a characteristic feature of most ABS-equipped vehicles. Which technician is correct?

Which type of antilock braking system (ABS) requires the use of four wheel speed sensors?

Two technicians are discussing ABS wheel speed sensors. Technician A says that some ABS systems use a sensor located in the rear-axle pinion gear area. Technician B says that all ABS systems use a wheel speed sensor at each wheel. Which technician is correct?

Technician A says that some ABS wheel speed sensors are used as part of the tire pressure monitoring system (TPMS). Technician B says that the ABS is used as part of the hill assist system. Whichtechnician is correct?

Technician A says that ABS brakes are designed to allow the front wheel to be steered during heavy braking. Technician B says that the ABS dash warning lamp is amber. Which technician is correct?

 A passive wheel speed sensor is also referred to as a ________ sensor.

An active wheel speed sensor is also referred to as a ________ sensor.

Which part of an antilock brake system is used for tire pressure monitoring?

Technician A says that ABS-equipped vehicles can stop quickly and without skidding on all road surfaces even if covered with ice. Technician B says that steering is possible during an ABS stop. Which technician is correct?

A customer wanted the ABS checked because of tire chirp noise during hard braking. Technician A says that the speed sensors may be defective. Technician B says that tire chirp is normal during an ABS stop on dry pavement. Which technician is correct?

Technician A says that most ABS units are non-integral.. Technician B says that some ABS wheel speed sensors do not produce a useable signal below about 2 mph (3 km/h). Which technician is correct?

The faster a wheel rotates, the higher the frequency produced by a wheel speed sensor.

Technician A says that some wheel speed sensors are enclosed in a wheel bearing assembly. Technician B says that some wheel speed sensors are exposed to possible damage from road debris. Which technician is correct?
