Spring brakesQuestion 28 of 116

Why is a corroded spring brake chamber dangerous?

  1. The brake lining can freeze
  2. The air dryer can fail
  3. The governor can cut out early
  4. The park spring can escape with great force
Show answer

Correct answer: The park spring can escape with great force

Corrosion weakens the chamber. The compressed spring can then escape and cause severe injury or death.
