How To Read Your Brakes
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. |
