Advantages of Air Disc Brakes
Shorter stops
Research shows that fully loaded trucks equipped with air disc brakes traveling at 60 mph can come to a complete stop in about 200 feet, 20 feet shorter than trucks with reduced stopping distance drum brakes.
Better braking feel
Air disc brakes provide more of a passenger-car feel than drums, giving drivers more control when stopping.
Longer service life
Air brakes feature an “open” design, which allows air to flow over the pads and rotors. This cools the brake mechanism and can extend the life of a air disc brake’s friction material up to twice as long as that found in drum brakes.
Fewer maintenance concerns
Air disc brakes are inherently self-adjusting and have no “stroke” to measure, so trucks are less likely to be marked as out-of-adjustment at roadside inspections. Plus, air disc brakes have fewer moving parts than drums, minimizing the likelihood of repairs.
Faster pad changes
On average, friction material can be changed in just 15 minutes per brake with air disc brakes (once the wheel is removed), compared to the one hour per wheel it takes for drums.

Procedure for Replacing Air Disc Brakes
Preparation
Park the vehicle on a flat surface and engage the parking brake. Use wheel chocks for added safety.
Remove the Old Pads
Release the brakes and back off the adjuster mechanism using a wrench. Remove the retaining clip, pin, and bar to take out the old brake pads.
Inspect Components
Before installing new pads, check the tappets, guide pins, and caliper for damage. Clean the carrier to remove any debris.
Install New Pads
Place the new brake pads into the carrier, ensuring they are properly aligned. Secure them with the new retaining bar, pin, and clip.
Adjust the Brakes
Tighten the adjuster mechanism until the pads make contact with the rotor, then back it off slightly to ensure proper clearance.
Final Checks
Test the brakes to ensure they engage and release smoothly. Check for any unusual noises or vibrations.
Precautions for Using Air Disc Brakes
● Ensure the brake chamber is securely fastened to the caliper, and check that the clamp is properly secured.
● Inspect the end caps for any damage such as punctures, dents, or excessive protrusion.
● Examine the slide pins for wear and ensure the caliper moves freely on them, particularly after the piston is extended. Look for any obstructions that may affect movement.
● Examine guide pin and piston boots to ensure they’re properly seated and free of damage, rips, and tears. When the caliper is fully inboard, the guide pin and piston boots should pull a vacuum and collapse.
● Verify that the adjustment mechanism maintains the correct clearance. If the brake doesn't adjust automatically or if clearance is excessive, further inspection is needed.
● Check for water entry, especially around the air chamber and adjustment mechanism, as moisture can affect brake performance.
● If the caliper does not slide properly or components are damaged, replace the caliper or pins and bushings.
● Clean the caliper assembly regularly, removing grease, oil, and contaminants from the rotor and linings.
● Lubricate the slide pins and bushings to ensure smooth movement. Replace any damaged components.
● When de-adjusting the brake mechanism, use an extension and ratchet wrench, avoiding excessive force and rotating in the correct direction.
● By following these inspection and maintenance practices, you can ensure the caliper remains in optimal working condition, enhancing braking reliability and vehicle safety.
