brake booster

[Tourniqet]

aren't the boosters stuck together by like metall.. ( baisically almost impossible to get apart?)

...Moved from another thread....

This is EXACTLY what is wrong with my car and yes, I did remove the engine side of the rod to compare the length with my existing (it was adjusted in way shorter which I chalked up to being in an auto? Probably not correct, but that is not the issue at hand). The rod did offer a bit of resistance the first time I pulled it out and from then on it was just floppy. Reaction disk huh? So....to reiterate and unanswered quesiton: Can you get a booster apart? Does not look like fun.

Or, couldn't you just adjust the rod out longer to compensate for the dropped disk? Or is it more complicated than that?

If the reaction disc is the problem, the only fix I have heard is to pull the booster, then tip and turn it until you find the disc and replace it securely where it belongs.

I believe that the booster can be opened but special tools are required.

And where does it belong? Sounds like I need a new booster.

Right behind the rod that you mentioned (center of the booster). If you have an FSM, I believe (could be wrong, since it's been a while since I looked) that there is a illustration that shows the part.

As for needing a new one, well..........I guess that depends on if you have extra money to spare, or cannot find the disc to reinstall. They aren't cheap by my standards.

The Haynes manual has a section on how to take apart and rebuild a sevo. But I heard only the early (1970-1972) booster can be rebuilt 'at home'.

FWIW

So i guess I have the wrong special tools...

My hammer, screwdriver, and vise were not special enough i guess...

So you say you just have to flip flop it around untill the disk just kind of goes back into place? Or you take the rod out to look into it and then try to get it back?

If either of you end up not being able to fix it shoot me an email or PM, I have one for sale.

If the disc has fallen out from where it belongs, you remove the booster, take the rod out and twist and shake the booster until the disc (hopefully) reappears. Then you grab it (disc) and when the booster is installed, you carefully reinstall the disc where it belongs, insert the rod, mount the M/C. If nothing else is wrong, your brakes should work right.
