All was well with the first 3 corners of my brake flush this Sunday, but I snapped the bleed screw off on the driver's side front.

Wondering if anyone knows:
1) Was there only the one supplier for the front brake in 1989? I know until 1988 it was Girling and Teves (from the Haynes), but the selection on RockAuto is downright confusing - they only ID girlings, most don't indicate either.

2) Can anyone confirm the bleed screw is M8x1.25? If possible, I'd like to just replace it.

3) Anyone have experience drilling out the bleed screw?

4) To prevent air getting up to the ABS Unit, can I clamp the brake line?

Thanks!

Well, I've never experienced this before, but I can't see how you'd be able to remove a snapped bleeder with the caliper on the car. Once you do get it out, speed bleeders are a good option. I think they're very convienient.

As for clamping the brake hose, EricTheCarGuy says you'll be fine. I agree for a few reasons, one of which is that a healthy brake hose should not be damaged by clamping for a little bit. If it collapses, it was old anyway and you should replace all 4 wheels' worth. That said, don't leave it clamped for days on end. :eek:

This option may revolutionize your auto-life. Bleeding brakes and clutches with these made me feel stupid for not doing this years ago.
