During a safety inspection, a technician finds the parking brake holds the vehicle on level ground but not on a grade. What is the most likely cause?
Answer: Rear brake shoes or pads need adjustment or replacement
Worn or out-of-adjustment rear friction components reduce parking brake holding force on inclines.
A tire shows wear concentrated on both outer shoulders with the center tread intact. What does this indicate?
Answer: Chronic underinflation
Underinflation lets the tire sidewalls carry the load, wearing both shoulders faster than the center.
Which measurement is used to determine if a brake rotor must be replaced rather than resurfaced?
Answer: Discard (minimum) thickness stamped on the rotor
If machining would bring the rotor below its minimum thickness specification, it must be replaced.
While checking steering components, a technician observes play in an inner tie rod with the wheels on the ground. What is the correct inspection technique to confirm?
Answer: Squeeze the rack boot and feel for socket movement while a helper rocks the steering wheel
Feeling the inner tie rod socket through the boot while the steering wheel is rocked reveals looseness in the joint.
A vehicle's exhaust system has a leak upstream of the catalytic converter near the passenger compartment. Why is this a safety concern?
Answer: Carbon monoxide can enter the passenger cabin
Exhaust leaks near the cabin can allow odorless carbon monoxide to reach occupants.
When inspecting a windshield, which defect typically causes a vehicle to fail a safety inspection?
Answer: A crack within the driver's critical viewing area
Cracks in the driver's primary viewing area obstruct vision and are a common inspection failure item.
A brake pedal slowly sinks to the floor while steady pressure is held with the engine running. What is the most likely cause?
Answer: Internal leak past the master cylinder piston seals
A slowly sinking pedal under steady pressure without external leaks usually points to master cylinder internal bypass.
