Technician A says that a bleeder screw wrench is needed to manually bleed brakes. Technician B says that a length of plastic hose and clear jar should be used when manually bleeding brakes. Which technician is correct? - answer-Both technicians A and B Technician A says that the bleeder valves must be located at the highest part of the caliper or wheel cylinder. Technician B says that the bleeder valves have a hole in the center. Which technician is correct? - answer-Both technicians A and B Technician A says that the brake pedal should be depressed with as much force as possible during the normal bleeding procedure. Technician B says that the brake pedal should be pumped rapidly during this manual bleeding procedure to force the air down toward the bleeder valve(s). Which technician is correct? - answer-Neither technician A nor B Technician A says that the wheel brake farthest from the master cylinder is generally bled first. Technician B says that the wheel brake closest to the master cylinder is generally bled first. Which technician is correct? - answer-Technician A only Technician A says to bleed the conventional brake system before bleeding the ABS modulator. Technician B says a scan tool may be required to bleed the ABS modulator. Which technician is correct? - answer-Both technicians A and B The bleeder is opened at a caliper and no brake fluid flows out. Technician A says that this is normal and that brake fluid should not flow or drip out of an open bleeder valve. Technician B says that the vent port in the master cylinder may be blocked. Which technician is correct? - answer-Technician B only The brake bleeding procedure usually specified for a rear-wheel drive vehicle with a dual split master cylinder is ________. - answer-RR, LR, RF, LF The button on the ________ valve should be held when pressure bleeding the brakes. - answer-metering The usual maximum pressure that should be used when pressure bleeding a brake system is ________. - answer-30 psi Two technicians are discussing bench bleeding a master cylinder. Technician A says that the front (nose end) of the master cylinder should be bled first. Technician B says that the rear (brake pedal end) should be bled first. Which technician is correct? - answer-Technician B only Two technicians are discussing bleeding air from the brake hydraulic system. Technician A says to depress the brake pedal slowly and not to the floor to prevent possible seal damage inside the master cylinder. Technician B says to wait 15 seconds between strokes of the brake pedal. Which technician is correct? - answer-Both technicians A and B Two technicians are discussing how to loosen bleeder valves. Technician A says that a shock is usually necessary to break the taper at the base of the valve. Technician B says to apply steady, loosening torque to the bleeder valve using a 6-point wrench. Which technician is correct? - answer-Technician A only Vacuum bleeding requires ________. - answer-a suction pump Vacuum is applied where during vacuum bleeding? - answer-At each wheel brake bleeder valve When bleeding the brakes on a vehicle equipped with an antilock brake system, what is the function of the scan tool? - answer-To cycle the solenoids in the ABS unit When bleeding wheel brakes, the bleeder screw is usually loosened one-half turn. - answer-True When manually bleeding the wheel brakes, press the brake pedal rapidly to the floor. - answer-False Which of these is NOT a method of brake bleeding? - answer-release While bleeding brakes, how long should you wait between strokes? - answer-15 seconds Why shouldn't a service technician depress a brake pedal all the way down when bleeding brakes? - answer-The sealing cups can be damaged.

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

degrees C)

If the weight of a car doubles, its kinetic energy ________. - answer-doubles

Rear brakes do less work during hard braking than the front brakes because ________. -
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
