Brake Maintenance
Best Practices to Keep Your Brakes in Good Condition
Air SystemsEnsure your brake system is well-balanced.
ChambersMake sure your push rod is even on all chambers. To help, cut the push rod to the appropriate length.
Slack AdjusterFirst, set your thorn up properly. 90 degree rules for manual apply. Also, use templates for automatic slacks (Exception: Haldex).
S-CamsMake sure no grease is on your S-cam head. Aim for free play movement in and out, and up and down. Also, seal your installation.
Hardware KitsReplace these completely, not only the springs.
ShoesDo a complete replacement, not only one wheel. The minimum should be a complete axle if it's not possible to do an entire unit.
DrumsMake sure to use heavy drums for severe applications.
Lining Wear PatternsTo begin, after removing drums look at the brake shoes and lining before you remove them off the wheel - it will tell you a story.
Brake AdjustmentJack up axles and snub up brakes, then back off ¼ to ½ turn on manuals and use templates on automatics.
Brake Lining BurnishingsHeat up the brakes until you are able to smell them. Then, allow them to cool. Do this procedure within ¼ to 1 mile. Check wheel temperature with a heat gun.
