Well, yesterday after installing a caliper and then bleeding the entire system, when I was on the last bleed sequence (lower front), the bleed valve broke off on the first pull (yes, I had PB Blaster'd them prior to the job). S___ happens! Well, I was told to just drill out the remainder of the broken screw, vacuum the hole and spray it out with brake cleaner or brake fluid, use a screw extractor, and IF I get it out, then install new bleed screw. The metal drill particles will push backwards and not enter the caliper hydraulic cavities.

But another guy tells me that the metal filings from the drilling will go into the caliper cavities, eat up the seals, and can't be gotten out because they sink to the bottom and bleeding will not remove these metal particles. New caliper is the only solution.

Both approaches sound logical. I prefer the first solution. I'm getting really sick and tired of replacing parts on this car. Anyone do this job with success?
