Brake stroke and lighting inspection

You will find detailed information elsewhere in this textbook that explains the procedure for checking brake stroke and lighting. It does not take much to identify a failed lamp, but repairing the circuit that supplies it requires a higher level of skills that are covered in the electrical chapters of this book. Similarly, anyone working on trucks should know how to identify an out-of-adjustment brake stroke. Remember that the CVSA overstroke limits shown earlier in this chapter are not the required inspection performance standards. Correcting an overstroke condition is covered in greater detail in the chapters on brake systems later in this textbook.

CAUTION: When an automatic slack adjuster overstrokes, the TMC recommends not to manually adjusted it. The cause is usually a defect in the adjusting mechanism. The recommendation is that the cause of the overstroke be identified; that often requires the replacement of the slack adjuster.
