Q1: During a routine Michigan state brake inspection, a technician measures the front
brake pad thickness on a 2019 sedan. The inner pad reads 3/32 inch and the outer pad
reads 5/32 inch. According to Michigan inspection standards, which of the following
statements is correct?
A. Both pads pass inspection since the average thickness exceeds 2/32 inch.
B. The inner pad fails inspection because any pad below 4/32 inch is considered unsafe
under Michigan standards.
C. The inner pad fails inspection because Michigan standards require each individual
pad to meet minimum thickness requirements, not an average. [CORRECT]
D. Only the outer pad needs to be measured because the inner pad is protected from
wear.
Correct Answer: C
Rationale: The best answer is C. This choice is correct because Michigan state inspection
standards look at each brake pad individually — you can't average a worn inner pad
with a thicker outer pad to get a passing grade. In a real shop situation, the proper
procedure would be to measure every pad separately and flag any pad that's worn
down to or below the minimum spec.
,Q2: A customer brings a 2015 pickup truck in for its annual Michigan safety inspection.
The technician notices the brake warning light on the dash stays illuminated after the
engine starts. The brakes feel normal during a brief test drive. How should this be
handled under Michigan inspection protocol?
A. Pass the inspection since the brakes perform adequately during the test drive.
B. Fail the inspection because a functioning brake warning light is required for
compliance, regardless of brake performance. [CORRECT]
C. Pass the inspection with a note to the customer to have the light checked at their
convenience.
D. Fail the inspection only if the ABS light is also illuminated.
Correct Answer: B
Rationale: The best answer is B. This choice is correct because a brake warning light that
stays on is an automatic failure under Michigan inspection standards — that light is
there to tell you something's wrong, and you can't just ignore it because the brakes feel
okay. This aligns with Michigan state inspection standard that requires all warning
systems to function as designed.
Q3: Which of the following brake fluid conditions would cause a vehicle to fail a
Michigan state brake inspection?
A. Brake fluid that is amber in color but at the proper level.
B. Brake fluid that is dark brown, has a burnt odor, and contains visible particulate
contamination. [CORRECT]
C. Brake fluid that is clear but filled 1/4 inch above the maximum fill line.
D. Brake fluid that has been recently replaced with DOT 4 fluid in a system originally
spec'd for DOT 3.
Correct Answer: B
,Rationale: The best answer is B. This choice is correct because contaminated, burnt
brake fluid indicates moisture absorption and degradation, which compromises braking
performance and is a clear safety violation under Michigan inspection guidelines. In a
real shop situation, the proper procedure would be to flush the system and replace the
fluid before the vehicle can pass.
Q4: During a Michigan brake inspection, a technician discovers a brake line on a 2010
sedan with surface rust covering approximately 40% of the line's visible length. The line
shows no signs of leaking, swelling, or structural weakness when gently probed. What is
the appropriate inspector determination?
A. Pass the line since there is no active leak and the rust is only surface-level.
B. Fail the line because any visible rust on brake lines is automatically a rejection item.
C. Pass the line with a recommendation for replacement if the rust progresses beyond
50% coverage.
D. Fail the line because surface rust on brake lines can mask deeper corrosion and
compromise structural integrity over time. [CORRECT]
Correct Answer: D
Rationale: The best answer is D. This choice is correct because Michigan inspectors are
trained to look at brake lines critically — surface rust isn't just cosmetic, it's often the tip
of the iceberg, and you can't reliably tell how deep it goes without further inspection.
This matches the manufacturer specification that brake lines must be free from
corrosion that could affect their structural integrity.
Q5: Under Michigan state inspection requirements, what is the minimum acceptable
performance standard for a vehicle's parking brake system?
, A. The parking brake must hold the vehicle stationary on a 10% grade in both forward
and reverse directions. [CORRECT]
B. The parking brake must hold the vehicle on any grade up to 25%.
C. The parking brake only needs to hold the rear wheels when the transmission is in
"Park."
D. The parking brake must engage within the first three clicks of pedal or lever travel.
Correct Answer: A
Rationale: The best answer is A. This choice is correct because Michigan state inspection
standards require the parking brake to hold the vehicle on a 10% grade — that's the
baseline test you perform in the shop or on the inspection lane. In a real shop situation,
the proper procedure would be to test on a known grade or use a calibrated incline to
verify holding power.
Q6: A 2012 SUV comes in for inspection with a spongy brake pedal that travels nearly to
the floor before firm resistance is felt. The technician finds no external leaks, the master
cylinder reservoir is full, and the brake pads have plenty of material remaining. What is
the most likely cause of this condition that would result in a failed Michigan inspection?
A. Worn brake pads causing excessive caliper piston travel.
B. Air in the hydraulic system or internal master cylinder bypass. [CORRECT]
C. Over-adjusted drum brakes causing premature lockup.
D. A faulty ABS modulator cycling incorrectly during normal braking.
Correct Answer: B
Rationale: The best answer is B. This choice is correct because a spongy pedal that sinks
to the floor typically means there's air trapped in the lines or the master cylinder seals
are bypassing internally — both are serious safety issues that would fail a Michigan
