Tech A says that a metal-on-metal grinding noise in drum brakes generally requires replacing
the brake shoes and resurfacing or replacing the drums. Tech B says that one way to help
identify whether a problem is coming from the front or rear brakes is to test-drive the vehicle in a
safe place at a relatively low speed and lightly apply the parking brake. Who is correct? - correct
answer-✅both A and B
Tech A says that most brake drums are designed to be machined if minor surface issues are
present. Tech B says that brake drums can be reused if they are machined larger than
specifications, as long as the surface is smooth. Who is correct? - correct answer-✅Tech A

correct answer-✅It is standard practice to hone out deep pits in the wheel cylinder bore.
The component of the drum brake system attached to the backing plate is the: - correct answer-
✅wheel cylinder
Tech A says to use an air hose to clean the backing plate of dust and contamination. Tech B
says to use a water-based cleaning solution to clean the backing plate of dust and
contamination. Who is correct? - correct answer-✅Tech B
Among the tools used to diagnose and repair drum brake systems, the wheel cylinder piston
clamp is used to: - correct answer-✅hold the pistons in the wheel cylinder while the brake
shoes are removed.
Choose the correct statement: - correct answer-✅The backing plate has holes stamped in it.
Tech A says that duo-servo brake shoes are only anchored on the top. Tech B says that duo-
servo brakes typically use single-piston wheel cylinders. Who is correct? - correct answer-
✅Tech A
Tech A says that both secondary shoes should be installed on the passenger side of the vehicle.
Tech B says that the lining on the primary shoe is typically shorter in length than the lining on
the secondary shoe. Who is correct? - correct answer-✅Tech B
When the driver releases the brake pedal, the brake shoes are withdrawn by the: - correct
answer-✅return spring
, Which of the following brake tools is used to adjust brake shoes when the drum is installed? -
correct answer-✅brake spoon
Tech A says that when performing a brake job on the rear axle of an older vehicle, inspection
finds brake fluid under the dust boot; the wheel cylinder should be replaced. Tech B says that
when a drum brake return spring has failed, springs on both rear wheels need to be replaced.
Who is correct? - correct answer-✅both A and B
Tech A says that riveted lining is usually for heavy-duty or high-performance vehicles. Tech B
says that bonded lining is glued to the metal brake shoe. Who is correct? - correct answer-
✅Both A and B
Choose the correct statement: - correct answer-✅Riveted linings are used on heavier duty or
high-performance vehicles.
All of the following statements with respect to brake systems are true EXCEPT: - correct
answer-✅trailing shoes are self-energizing.
Tech A says that a cleaned-up self-adjuster can be installed on either side of the vehicle. Tech B
says that grease seals are meant to be reusable. Who is correct? - correct answer-✅Neither A
nor B
The component that prevents a direct path for water spray and dirt to enter the brake drum is
the: - correct answer-✅Labyrinth seal.
Tech A says that an antilock brake system (ABS) allows the front wheels to be steered during a
panic stop. Tech B says that ABS sensors apply or release hydraulic pressure to the wheel
brake units during ABS brake events. Who is correct? - correct answer-✅Tech A
If we triple the speed of an object, the kinetic energy will: - correct answer-✅increase by nine
times.
All of the below statements are true EXCEPT: - correct answer-✅Service brakes consist of
drum and/or disc brakes and are operated by hand.
Tech A says that tire pressure does not affect braking. Tech B says that heavy vehicle loads
increase stopping distance. Who is correct? - correct answer-✅Tech B
Tech A says that the heavier the vehicle, the more stopping power is needed. Tech B says that
the faster a vehicle is moving, the more braking power is needed. Who is correct? - correct
answer-✅Both A and B
Tech A says that water soaked brake shoes can be a cause of brake fade. Tech B says that disc
brakes dissipate heat faster than drum brakes. Who is correct? - correct answer-✅Both A and
B
Tech A says that kinetic energy is created during braking to stop the vehicle. Tech B says that
kinetic energy is converted to heat energy during braking. Who is correct? - correct answer-
✅Tech B
