,EXAMINATION OVERVIEW
This practice examination contains 150 multiple-choice questions covering the seven core competency areas tested on
the Michigan Secretary of State (SOS) Brakes Mechanic Certification Exam for the 2026/2027 testing cycle. Each
question presents four answer choices (A–D) with exactly one correct answer, followed by a concise rationale that
references the applicable Michigan Administrative Rule, ASE A5 competency, or industry best practice.
The examination is structured to mirror the cognitive distribution of the live certification exam: approximately 25%
recall (direct knowledge), 50% application (scenario-based), and 25% analysis (diagnostic reasoning and compliance
decisions). Approximately 70% of the questions are scenario-based, reflecting real-world inspection situations,
diagnostic scenarios, and Michigan-specific compliance decisions that a certified brake mechanic will encounter in
practice.
To maximize preparation value, attempt each question without referencing external materials, then review the rationale
for both correct and incorrect answers. Pay particular attention to the Michigan-specific inspection criteria in Section 1
(Admin Rules 247.791, 247.792, and 247.793), as these statutory requirements differ from general ASE A5 practice in
several important respects. The parking brake test (engine off, transmission in neutral) and the 2/32" friction material
failure threshold are two of the most commonly misunderstood Michigan-specific requirements.

Section 1: Michigan State Brake Laws, Safety Inspections, & MVSRA
Compliance
Q1: A 2019 Ford F-150 is presented for a Michigan state safety inspection. The front disc brake pads measure
3/32" on the inboard pad and 4/32" on the outboard pad. The rear drums measure 2/32" lining at one shoe.
According to Michigan Admin Rule 247.792, what is the correct inspection disposition?
A. Pass the front axle; fail only the rear axle because the front pads exceed 2/32".
B. Pass the vehicle because at least one pad on each axle exceeds 2/32".
C. Fail the vehicle because the rear shoe lining is at the 2/32" absolute legal minimum, which is the failure threshold,
not a safe operating thickness. [CORRECT]
D. Pass the vehicle conditionally, requiring re-inspection in 30 days.
Correct Answer: C
Rationale: Michigan Admin Rule 247.792 establishes 2/32" of friction material as the absolute legal minimum at which a
vehicle FAILS inspection; it is not a 'safe operating' thickness. Inspection is based on the thinnest pad or shoe at any
measurement point. Because the rear shoe is at 2/32", the vehicle fails. Options A and C misapply the rule by averaging pads
across an axle, and option D has no basis in Michigan statute. ASE A5 inspection practice mirrors this point-of-measurement
standard.

Q2: During a Michigan state brake inspection, a technician observes that a flexible front brake hose on a 2016
Honda Accord is damp on the outer surface near the caliper end, with no visible fluid dripping onto the ground.
Under Admin Rule 247.791, what is the required action?
A. Pass the hose, since fluid is not actively leaking onto the ground.
B. Pass the hose, but recommend replacement at the next service interval.
C. Wipe the hose clean and re-evaluate after a 10-mile road test.
D. Fail the hose, because 'wetness' on a brake hose indicates seepage and constitutes an automatic inspection failure.
[CORRECT]
Correct Answer: D
Rationale: Admin Rule 247.791 requires brake lines and hoses to be free from leaks, cracks, and deterioration. The rule
specifically treats external 'wetness' or dampness on a hose as evidence of seepage through the hose wall, which is an
automatic inspection failure regardless of whether fluid reaches the ground. Re-evaluation or conditional pass procedures are
not permitted under the rule. This aligns with ASE A5 inspection practice that treats hose seepage as imminent failure.
Q3: A Michigan-registered fleet operator asks a technician to certify the parking brake on a delivery van. The
operator requests the test be performed with the engine running and the transmission in gear to 'simulate
real-world conditions.' Under Admin Rule 247.793, how must the parking brake test be conducted?
A. Engine running, transmission in gear, to simulate real-world operation.
B. Engine running, transmission in neutral, to provide power brake assist.
C. Engine off, transmission in neutral, to eliminate engine braking contribution. [CORRECT]
D. Engine off, transmission in first gear, to provide mechanical lockup assistance.
Correct Answer: C
Rationale: Admin Rule 247.793 requires every motor vehicle to be equipped with a parking brake capable of holding the
vehicle stationary on a 20% grade. The test must be performed with the transmission in neutral and the engine OFF,
specifically to eliminate any contribution from engine braking or transmission park mechanisms. Testing with the engine
running or transmission in gear would mask a weak parking brake and is non-compliant. The rule's intent is to verify the
parking brake alone, in isolation.
Q4: Under the Michigan Motor Vehicle Service and Repair Act (MVSRA), a customer brings a vehicle in for a
'brake inspection only' and authorizes no repairs. The technician finds the front pads at 2/32". Which statement
correctly describes the technician's legal obligation?
A. The technician may install pads without further authorization because the vehicle is unsafe.
B. The technician may verbally quote the repair over the phone and proceed if the customer agrees.
C. The technician must provide a written estimate exceeding $50 or 10% of the total cost (whichever is greater)
before performing any repair work, and obtain customer authorization. [CORRECT]
D. MVSRA estimate rules apply only to repairs over $500, so no estimate is required for pads.
Correct Answer: C
Rationale: The Michigan Motor Vehicle Service and Repair Act (MVSRA) requires a written estimate for any repair
expected to exceed $50 or 10% of the total repair cost, whichever is greater, and the customer must authorize the repair
before work begins. Verbal authorization is not sufficient for repairs meeting the threshold. Installing pads without
authorization-even on an unsafe vehicle-constitutes unauthorized repair under MVSRA and exposes the shop to liability. The
technician should document the unsafe condition and decline to release the vehicle without customer action, but cannot
perform repairs without proper authorization.
