Title: Diagnose pressure concerns in the brake system using hydraulic principles (Pascal’s law).
Course: Automotive Technology III (20104-III) > Section: BRAKES: Hydraulic System

Diagnosis should include checking

- the metering process
- pressure differential and proportion valves
- the master cylinder
- hydraulic hoses and lines and wheel brakes.

Process/Skill Questions:

- What is Pascal's law?
- How does Pascal's law apply to the brake system?
- What are the differences between input piston size and output piston size?
