It was the last one of course. I was bleeding my brakes after installing new lines and a new master cylinder, and the last bleeder valve (Front Passenger) was pretty hard to unscrew. Halfway through unscrewing it I realized that the threaded piece that the bleeder valve was screwed into was unscewing also. I called VBP and they told me to send the calipers back, but I'd rather fix it myself. Any ideas how I can get the bleeder valve out without the thing it is screwed into coming out also?

I hope this makes sense to someone besides me.........

Bleeder screws into a tapped holein the casting,unless it was repaired using a Helicoil or insert. I had rebuilt calipers come in with bad bleeder screws-not drilled through but it sounds like you have a casting issue so I would get another caliper.

:iagree: Go the easiest and smartest route...

Mine aren't tapped into the casting. They are screwed into another screw (lack of better term) which is screwed into the casting. It is like that on both front calipers on my '82. Those calipers I bought in '97 from VBP. I have a new set for my '77 sitting on the bench that do have the bleeder screws tapped into the housing though. They came from AutoZone.

It is not a Helicoil though.

Sounds like they were bushed first? I'd still send them back if they're failing.

Helicoils will not seal a fluid hole, So I'd rule that out.
Could this be a speed bleeder ? I've never delt with those.....

I've never heard of a speed bleeder, but it looks like a regular bleeder to me. The other front caliper has the same setup and worked like a normal bleeder. I guess I'll just send them back to VBP since they said they'd take care of it. Just sucks that I have to wait. Patience is not one of my best virtues.

Thanks for the help though guys!

They've been helicoiled.... IMOP you got someone elses junk... happened to me too a long time ago on my C2.... I sent good cores and got trash in return. That was the last time I purchased sleeved calipers that way (about 1976).... had SSBC sleeve & return my own original calipers.

The bleeders seal at the tip, not in the threads. That's why you have to be very careful when drilling out a broken bleeder... the drill face angle does not match the bleeders angle requirement, if you hit the casting with the drill bit, you F it up and the new bleeder will not seal.

Send 'em back... ask for some "non-helicoiled" warranty replacements.
