Michigan State Brakes
Certification Exam
Questions and Answers
1. Basic Brake System Operation
Q1. What is the primary purpose of a vehicle’s braking system?
A. Increase engine power
B. Convert kinetic energy into heat energy
C. Improve fuel efficiency
D. Reduce emissions
Answer: B
Rationale: Brakes convert motion (kinetic energy) into heat via friction.
Q2. Brake fluid is classified as:
A. Compressible
B. Incompressible
C. Gas-based
D. Volatile
Answer: B
Rationale: Hydraulic systems rely on incompressible fluid to transmit force.
2. Hydraulic Systems
