New Threadlocker Must Be Applied To the Brake Nut Setscrews To Prevent Premature Brake Failure!

Install new brake body on 8-32 studs until seated on brake nut and flush as detailed in Figure 4. After disc is centered brake nut may be rotated slowly to allow brake nut to line up with brake disc. Install 8-32 nuts and tighten - threadlocker is not required on these nuts.

Remove the two black wires from the old brake body from their wirenuts (attached to the red and black wires). Install the new brake body wires in the same manner as the old ones were removed. Either black brake wire may be connected to either the red or black wires - polarity is not important. Be sure not to reverse the wiring of the diode. (POLARITY DOES MATTER ON THE DIODE). Be sure wire nut setscrews are secure. Refer to Figure 5 for details of this step.
