Sensor installation
Epoxy the small rare earth magnet into the disk. Drill out the hole in the carrier to 17/64”. Thread the hole with an 8x1.25 tap. Remove any jam nuts on sensor and thread the sensor into the hole being careful not to twist the wire . Do not force sensor. If it is too tight use some oil or recut threads. Removing the carrier will make this easier. Position sensor so it is about 1/16” away from magnet.
The correct method for routing the sensor wire is shown at bottom left. The wire is routed along the brake cable all the way to the master cylinder, then back across handlebar. Make the connection to the computer and zip tie the connector so it does not move. This will last forever. Do not route sensor wire directly from computer to the brake line. This will stress the sensor wire every time the forks compress and will quickly wear out the wire.
First find a protected spot on or near the caliper carrier that you can drill and tap. Make sure the selected spot is over a part of the brake disk that can be drilled for the magnet. Drill thru the carrier and into the brake disk with a 3/16“ drill. Just spot drill the disk for now. Rotate the disk and finish drilling for the magnet. Go about 1/64” deep...about 1/2 the thickness of the magnet.
