HI folks. Always appreciate the great help I get here. I snapped a bleeder valve on the rear brake caliper of my 2004 TB LS. Can I put flame on it to hopefully improve the chances of using a screw extractor? Recommended drill/extractor sizes? I'd like to try that first before trying to tap a new hole. (How difficult is that?) PS. What size valve is it to replace (if I'm successful)? Thanks.
