IMPORTANT INSTALLATION NOTES:

✔ Mount the caliper and torque fasteners to OEM specifications.
✔ Turn the adjuster COUNTER-CLOCKWISE until the brake pads just contact the rotor (avoid over-tightening).
✔ Then turn CLOCKWISE 1/4 turn to set clearance
✔ Confirm system air pressure is between 100–120 psi.
✔ Block and secure wheels to prevent any movement.
✔ Depress the emergency brake release button on the dash to release spring brakes.
✔ Only after the wheels are secure and spring brakes are released should you proceed with caliper adjustment.
