    rebuilt my calipers cup seals, put it all back together and sure enough the hole to tighten up my caliper bleed screw was stripped. I didn’t have a tap set and it was raining so I called it quits after a long day. anyone have an idea on the size of that bleed screw so I can try and tap it… last resort would be to by a new caliper I guess… $220 unless someone has one, it is pretty much obsolete at this point unless you are me (on a budget). ¬†thanks.

    comet karts, super nice…. guy told me the bleed screw is 5mm .8 pitch… new bleed screws are 10mm, vs the 8mm in the factory diagram, I guess the realized it need a little more bite…
