Brakes Exam Questions with 100%
Correct Answers 2024/2025 Latest
Update
Dual-servo brakes use different lengths brake shoes. Why does the shoe with the
longer lining go to the rear? - Answer-Because of the stopping energy needed in
reverse, and because the greater amount of heat and pressure the secondary shoe
receives
The location of the anchor pin is different for dual-servo and non-servo brakes, where is
the anchor located on non-servo brakes? - Answer-At the bottom of the backing plate
The function of the wheel cylinder is to? - Answer-Convert hydraulic pressure into a
mechanical force at the brakes
Brake shoes should be replaced when - Answer-The linings are worn within .060" inch
of a rivet head
Linings contaminated with oil or grease
Linings contaminated with brake fluid
Brake shoes return springs need to be inspected for what? - Answer-Coils touching
together
Make a thud sound when dropped
Distortion
What should be done before removing a brake drum? - Answer-Wash drum down with a
water based cleaner
The automatic adjuster system uses a star wheel and a lever. Tech A says the star
wheel adjuster is the same for both sides. Tech B says the star wheel adjuster is a right
hand thread for one side , and a left hand for the other side. Who's correct - Answer-
Tech B
The star wheel adjuster is turned when? - Answer-The shoes are released after
stopping backwards
Hydraulic fluid in a closed hydraulic system is - Answer-non-compressible
, Two technicians are discussing a problem where the brake pedals travels to far before
the vehicle starts to slow. Tech A says that the brakes may be out of adjustment. Tech
B says that one circuit from the master cylinder may be leaking or defective. Who's
correct? - Answer-Both
Air in the lines will causes what type of problem - Answer-Low spongy brake pedal
Brake fluid provides lubrication to the components in the hydraulic system. Tech A
states that brake fluid also absorbed moisture. Tech B says that it is important property
of brake fluid so the lines will not freeze in cold weather. Who is correct? - Answer-Both
If the brake pedal linkage is not adjusted correctly, brake fluid may not be able to
expand back into the reservoir through the ____________ port of the master cylinder
when the brakes get hot. - Answer-Vent port (Forward hole)
The rear wheels lock up during hard braking. Tech A says that a defective metering
valve could be the cause? Tech B says that a defective proportioning valve could be the
cause? Who is correct? - Answer-Both
Tech A says that some proportioning valves are one part and used to control both rear
brakes. Tech B says that some proportioning valves are two parts, one for each rear
wheel - Answer-Both
The button on the __________ valve should be held when pressure bleeding the
brakes. - Answer-Metering
Two types of flares used in brake lines are? - Answer-ISO and Double flare.
Two technicians are discussing why the brake lines are coiled near the master cylinder.
Tech A says that is is to reduce moisture from getting into the master cylinder. Tech B
says that helps prevent cracks that could be caused by vibrations. Who's correct? -
Answer-Tech B
Flexible brake hose should be inspected for all of the following expect? - Answer-Worn
outer ribs
Two techs are discussing bench bleeding a master cylinder. Tech A says that the
front(nose end) of the master cylinder should be bled first. Tech B says the rear(brake
pedal end) should be bled first. Who's correct? - Answer-Tech B
Vacuum is applied where during vacuum bleeding? - Answer-At each wheel brake
bleeder valve.
The bleeder is opened at a caliper and no brake fluid flows out. Tech A says that this is
normal and that brake fluid should not flow or drip out of any open bleeder valve. Tech
