Air brake system slack adjustment

It is a known thing that your brake system may eventually need adjustment. You know this when the car doesn’t stop as it used to. Follow these steps:

  1. You have to remember or note down the brake chamber you work on because they have own brake push-rod stroke limitations.
  2. Locate the slack adjuster nut and an appropriate wrench to adjust it.
  3. Now you have to turn the adjuster and make sure it’s in the right direction. You shouldn’t see free play on the wheels
  4. While tightening in a counterclockwise direction check the brake drum and brake shoes not to touch. Stop at that moment.
