Brake Adjustments Not Holding

Possible Causes
Adjustment not HoldingIf the slack adjuster angle is more or less than 90° at readjustable stroke length, the push rod can be the wrong length, which can cause frequent brake adjustments.
Adjustment not HoldingCheck slack adjuster for internal wear. See how far it moves before the S-cam rotates. Push rod movement should relate to shoe movement against the drums.
