Default Broke bleed screw

hey there guys, i got a bone-stock 94 civic.

when i pish the brake pedel, the thing goes all the way to the floor, so i thought "well ill see what happens if i just bleed the brakes"

I took off the pass. side wheel, and the bleed screw opened up real nice, very easily (i know they often seize)

so im thinking that this job should be quick and i wont have to wrestle with it. WRONG

i took off the drivers side, and tried to move the bleedscrew, and it snapped without any warning. there is still a little bit above the caliper.

I'll probably end up drilling and tapping all this in an attempt to save my caliper.

are there any tricks to getting something like this out?

past experiences?

thanks.

You may be able to insert a properly sized reverse thread bolt extractor (e.g., picture) into the hole of the bolt and unscrew the broken portion. Then simply purchase a replacement bleed bolt. Note that it may be necessary to drill the hole to a larger size before using the extractor tool.

I'd go ahead with what RonJ recommended. I've used one of those to remove several snapped bolts.

I'm not sure if this is a good idea, but you may want to clamp the brake line on this side. On the one hand, you may loosen the bolt and get lots of air bubbles in the system and brake fluid will drip everywhere. On the other hand, you might just damage the line by clamping it. Anyone else have input about this?

yeah, im going to try to use an "easy out" bolt extractor today. do these thing use DOT 3 or 4 brake fluid.

4 in synthetic, and 3 is not i belive.
