Hi RAMVA!
Time to tackle a few problems on the bug (1970 standard with factory discs front). The brakes need some care, already ordered a master cylinder (mine has low pressure on the back) and replaced the center line. While bleeding the brakes and replacing bleeding screws that were difficult to turn (the front ones were almost round), I accidentally broke one of the bleeder screws. So, I figured I could take it out with an extractor bit and the small T-handle from my tap and die set. Well, no luck.
How can I take the broken screw out without messing up the threads? The calipers are ATE.
