How are many long-stroke brake chambers identified?
- A.By a longer air hose than the other chambers
- B.By the slack adjuster being painted red
- C.By markings or tags from the maker and features such as a distinctive chamber shape or port arrangement described in the service information
- D.Long-stroke chambers cannot be identified without removing the drum
Correct answer
C. By markings or tags from the maker and features such as a distinctive chamber shape or port arrangement described in the service information
Why
Correct identification matters because the allowable stroke is greater for a long-stroke design. Drivers and inspectors should rely on the maker's markings and specification, not on a guess based on appearance alone.
