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, with maybe 2 sets of threads showing.

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 rebuilts is downright confusing.

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!
