Title: Test the anti-compounding brake function.
Course: Diesel Equipment Technology II (20107-II) > Section: Brakes: Servicing the Parking Brakes

Testing should ensure that simultaneous applications of the service brake and the parking (spring) brake forces to the slack adjuster do not occur.

Process/Skill Questions:

- When the treadle valve is applied, does it continue to exert force? Why, or why not?
- How does the anti-compounding valve prevent over pressuring the spring brake chamber?
