Brake Adjustments Not Holding

Possible Causes	If 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.
Solution	Check 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.
