✔ Mount carrier using OEM hardware; torque fasteners to Bendix/Freightliner specifications.
✔ Confirm rotor compatibility: 430 mm OD, 45 mm thickness (new), 37 mm minimum discard.
✔ Ensure ABS sensor alignment; tone ring is mounted to the rotor, not the carrier.
✔ Replace both carriers/calipers on the same axle simultaneously for balanced braking performance.
✔ Inspect mounting flange and hub face for corrosion or damage prior to installation.
