I have received several inquiries to the installation of a disc brake on the above winches so thought I would post this. The conversion consists of two adapters which bolt to the case (using existing tapped holes), a caliper mounting plate, Kawasaki motorcycle caliper, snowmobile disc, remote master cylinder, and a remote reservoir. Hopefully, the jpgs will be self explanatory. Briefly, the disc assembly only needed bored and rekeyed to fit the former brake drum shaft; the three pieces for the mounting were whittled out of 6061 stock; a remote master was mounted below the floor (7/8 is very much overkill but is what I had), on a bracket bolted to the center cross member-operated by the right hand brake level between the seats (left is mechanically linked to D18 brake), and a firewall mounted remote reservoir that feeds the master. My setup was put together sometime in the mid 70's, and there are a lot more options for building something like this now as both ATV's and snowmobiles have hydraulic disc brakes and it is likely one could just transplant a complete system. My disc is only about 3/16 thick but given the hopefully slow speed at which it works, I do not think you could ever get it too hot in operation and I do not think you can wear out a set of pads. When I first built this, my tooling consisted of a drill press, hacksaw, and jig saw. It was refined to its present configuration after I purchased a mill in 1977 and has remained maintenance free since.
