Using existing hole in bleeder screw for pilot, drill hole of appropriate size (3/16” for 1/8 NPT, 1/4” for 1/4 NPT) completely through existing bleeder.
Increase hole to size recommended on top shank making sure to drill hole as straight as possible. (It may be necessary to increase hole size by 1/8" increments to reach the proper size diameter hole, making sure final drilling is completely through old bleeder.)
Tap hole using a taper pipe tap, at least 1/2" deep full thread.
Check, making sure bleeder hole is clear and free of any foreign material. Lubricate threads and install assembled bleeder repair fitting. Tighten repair fitting to 30-35 foot pounds torque.
Reassemble caliper. Be sure to check for possible leakage after installation and under pressure around threads. If any leakage should occur, loosen repair fitting and retourque fitting to 35 pounds.
Note: Minimum stock around hole after drilling should be at least 1/8".
