Adjusting The Brakes
Adjusting the brakes of your vehicle is an essential maintenance task that should be performed regularly to ensure proper functioning and safety. Properly adjusted brakes contribute to reliable stopping power and overall vehicle performance. Following the correct process is crucial to achieve optimal brake adjustment. In this section, we will guide you through the step-by-step process of adjusting self-adjusting air brakes, starting with preparing the vehicle for adjustment.
Preparing The Vehicle For Adjustment
Before you start the adjustment process, it is vital to ensure that the vehicle is properly prepared to allow for accurate adjustment of the brakes. Here are the preparatory steps:
- Ensure the vehicle is on a flat and level surface to work on.
- Place wheel chocks behind and in front of the wheels to prevent unexpected vehicle movement.
- Engage the parking brake to secure the vehicle in place.
Step-by-step Process Of Adjusting The Brakes
Now that the vehicle is adequately prepared, you can proceed with the adjustment process. Below are the step-by-step instructions to adjust the self-adjusting air brakes on your vehicle:
- Start by locating the brake adjustment access hole on the backside of the brake assembly.
- Use the appropriate tool, commonly a brake adjustment spoon, to turn the adjustment wheel or screw in a clockwise direction to tighten the brakes or counterclockwise to loosen them.
- Turn the adjustment wheel or screw in small increments, continuously checking the brake shoe clearance by spinning the wheel hub and listening for any rubbing or contact between the brake linings.
- Continue making adjustments until the correct clearance is achieved, ensuring that the brake shoes are not excessively tightened or overly loose.
- Once the proper clearance is obtained, recheck the adjustments on all wheels, and ensure that the adjustments are uniform across the entire braking system.
- After completing the adjustments, remove the wheel chocks and disengage the parking brake before testing the vehicle to ensure the brakes are functioning correctly.
Benefits And Safety
Learn the benefits and safety of adjusting self-adjusting air brakes. Follow the proper steps to ensure efficient performance and safe operation. Proper adjustment prevents brake issues and maintains vehicle safety on the road.
