Booster broke any ideas?
My booster broke on install. I pressed the pedal and this thing popped out. Anyone know why?
Also is this fixable or should I just replace it? Thanks for your input!

Re: Booster broke any ideas?
Damn son. How big is your foot?
I don't think I've seen that happen before. Is that an imported booster by chance?

Haha! I pressed the pedal with my hand while working under the dash the master cylinder wasn't hooked up at the time. I'm not sure where it was made. I got it from performance online.

Re: Booster broke any ideas?
Yeah, thats what I figured. It seems like that piece shouldn't be plastic.

Re: Booster broke any ideas?
It broke exactly for that reason, no master cylinder attached. There was no restriction of the cylinder bore, brake fluid=pressure, if nothing is there, she'll pop like a bullit

Re: Booster broke any ideas?
Now on some later boosters I have had the rod slide out and I just put it back in before putting on the M/C of course, but it didnt have any pieces broken. that bakealite piece shouldn't have broken like it did I would call them and see about a return. Did you mash the brake [break in this case]pedal without the M/C attached? That or a bed rod or booster housing or bad bakealite piece would be the only possible causes.

Well, I got another booster from a different manufacturer. And with a little bad luck and in a completely different way, knocked the thing out again. Being and different design, the piece came out with nothing appearantly being broken this time. Can I just push it back in place and trust that it won't come out after assembling everything? It doesn't appear to have anything fastening it in there. Seems weird..

Re: Booster broke any ideas?
You really ought to install a master cylinder onto the booster before you push the brake pedal again.
