failure or low brake fluid level. Technician B says that the red brake warning lamp on the dash
will light if there is a fault in the ABS. Which technician is correct? - answer-Technician A only
Technician A says that vehicles equipped with ABS will experience a pulsating brake pedal
even during normal braking. Technician B says that ABS will result in quicker stops on all road
surfaces. Which technician is correct? - answer-Neither technician A nor B

answer-Both the vehicle weight transfers forward and the rear tires have less traction are
correct
Technician A says that disc brake rotors may have internal passages for cooling. Technician B
says that the faster the vehicle is traveling when the brakes are applied, the greater the amount
of heat created in the brake system. Which technician is correct? - answer-Both technicians A
and B
Technician A says that the front brakes do most of the braking because the front brakes are
larger. Technician B says that due to weight transfer, most of the braking force needs to be
done by the front brakes. Which technician is correct? - answer-Technician B only
The amount of asbestos in brake friction material is being restricted because ________. -
answer-it is a health hazard
The front brakes on a vehicle do more work than do the rear brakes. Technician A says that this
is because the front wheel cylinders are closer to the master cylinder than are the rear wheel
cylinders. Technician B says that this is because the weight of a vehicle shifts to the front during
a stop. Which technician is correct? - answer-Technician B only
