Dexter Axle K23-398-00 Left Hand 7 x 1-3/4 Inch Hydraulic Uni-Servo Trailer Brake

The Dexter Axle K23-398-00 is a left hand (LH) 7 inch x 1-3/4 inch hydraulic uni-servo trailer brake, built for light duty trailer axles. It is a hydraulically actuated uni-servo brake assembly designed to mount on the left side of the trailer axle only -- the matching right hand assembly is sold under a separate part number, K23-399-00, so trailer owners replacing both sides need to order both part numbers rather than two of the same one. The uni-servo design uses a single hydraulic wheel cylinder to actuate both brake shoes, a common configuration on boat and utility trailer axles that keep the axle within the 600 to 8,000 lbs axle capacity range covered by Dexter's light duty brake line.

This assembly is intended as a direct replacement for a worn or damaged left hand 7 inch x 1-3/4 inch hydraulic uni-servo brake on a compatible trailer axle. Note that the axle spindle itself is not sold separately as part of this kit.
