Typical Applications

Trailer Axle Installations

Figures 10 through 13 show typical and alternative brackets for self adjusting brake adjuster installations on trailer installations.

Universal Anchor Bracket

Tip: The universal anchor bracket mounts to the “S” cam

bushing support bracket. Rockwell, Dana and Fruehauf brakes mount with two bolts. Position plate on adjuster side of the “S”

cam support. Added bracket thickness requires the use of longer mounting bolts. Eaton trailer axles manufactured after

January 1993 have the anchor bracket as an integral part of the "S" Cam shaft bushing support.

Refer to pages 9, 10 and 11 for detailed installation procedures.
