should be: - ✔✔adjusted properly
✔✔Upon inspecting brake fluid condition, the technician observes the diaphragm in the
master cylinder cup is swollen. Which of the following is the most likely cause? -
✔✔silicone fluid added to the system
✔✔When inspecting brake fluid levels, a technician observes low fluid levels. which of
the following should be done first? - ✔✔Inspect disc brake pads for excessive wear
✔✔Which of the following is true about most properly functioning anti-lock brake
systems? - ✔✔The brakes may lock up at speeds less than 10 miles per hour
✔✔Which of the following is true about bleeding brake lines on most ABS equipped
vehicles? - ✔✔Most ABS brake lines can be bled like a conventional (non-ABS) system.
However, caution must be taken because of the extreme pressure.
✔✔Most anti-lock brake systems require the removal of the pressure modulator fuse
when: - ✔✔a "spaced-saver" spare tire is being used and mismatched tires are being
installed
, ✔✔What does a load sensing proportioning valve do? - ✔✔It increases the hydraulic
pressure during braking at the rear wheel cylinders when the vehicle is loaded
✔✔Which of the following is a true statement about proportioning valves? - ✔✔They
provide better braking balance during hard stops
✔✔A properly functioning load sensing proportioning valve will: - ✔✔cause an increase
in the hydraulic pressure during braking at the rear wheel cylinders when the vehicle is
loaded.
✔✔Why don't disc brake system usually need adjustment? - ✔✔A certain amount of
pressure is maintained by the metering valve
✔✔Which of the following would be the LEAST likely cause for an intermittent problem
in an ABS system? - ✔✔Open wheel sensor circuit
✔✔Which of the following incorrect service procedures could cause brake pedal
pulsation? - ✔✔incorrect run-out on the car brake lathe
✔✔What type of rotor surface provides the best braking with new pads? - ✔✔A smooth,
flat surface
✔✔which of the following is a quick way to isolated a defective master cylinder? There
are no external leaks in the system. - ✔✔pump up the brake pedal, then hold it firm. if
the pedal slowly drops to the floor, the master cylinder may be defective.
✔✔A common cause of pedal pulsation during brake application is: - ✔✔NOT caused
by improperly torqued wheels, damaged backing plates, or lubricated shims
✔✔the car is at reset. When you slowly apply the brake pedal you hear a squeaking
noise at the rear of the vehicle. what could cause this noise? - ✔✔dry backing plate
contact surfaces
✔✔While test driving a car, the mechanic finds that the right front brake "grabs". The
most likely cause of this problem is: - ✔✔brake fluid or grease on the brake linings
✔✔Wheel speed sensors: - ✔✔send an A/C signal to the control module
✔✔Which of the following incorrect service procedures will cause brake lock up? -
✔✔Master Cylinder push rod adjusted too long
