SLACK ADJUSTER FAILURE

Proper brake stroke adjustment and maintenance are critical to roadway safety.

  • Measure chamber stroke by checking the distance from the chamber to the pin with the brakes released vs. full brake application. Ensure that this distance is within maximum allowable specifications for your vehicle
  • If an automatic slack adjuster has excessive chamber stroke, do not manually adjust it. Over-stroking is usually a sign of adjuster failure or a larger problem with the braking system
  • Light-duty braking cycles are a common cause of brake over-stroking. If insufficient torque passes through the adjuster, it may not cause the ratchet within the adjuster to advance. If this continues, the automatic slack adjuster is no longer compensating for the normal wear of the brakes
  • Recommended: On a regular basis, make a few full-pressure brake applications to cause the adjuster to turn over, and then visually check the stroke before leaving the yard
