So just for fun and being totally honest, can you answer the following?
Yes.
1. What are slack adjusters and what procedure should you follow to check them?
-They adjust the play in air brakes...exact procedure varies a bit, but basically: pull on the end of the adjuster. If it moves more than it should (1/2"-2", depending on type, and you should really know which ones you have), it's FUBAR.
2. Do you have 1 air tank or 2?
-Actually, I recall I have five...I have two air SYSTEMS.
3. How often should you drain your tanks?
-Daily, especially in cold weather.
4. At what pressure should the spring brakes apply
-20-40psi. (It's ~30 in my Genesis.)
5. What pressure should cause the low pressure alarm to sound
-60-90psi. (~70 in my Genesis.)
6. What is the maximum air pressure allowed
-120-125.
7. How many seconds should it take to build operating pressure
-85-100psi in 45 seconds or less at idle for a dual-air system, 2 minutes for single-air.
8. What are the 2 tests for air leakage
-Brakes off and brakes applied, parking brakes released in both cases.
9. What the are maximum leakage rates allowed
-2psi and 3psi in 60 seconds, respectively, for a single vehicle.How many can you answer without Googling?
All of them. :)
Also: 10. The air compressor should cut on at 95-100psi.
Oops, yes I missed 10. :)
Wear this with pride!
