Rebuilding the booster can be done heres how... (archive)

It requires taking out the whole booster. I have done it, its fairly simple if you pay attention to the spring inside and dont let parts fly (like I did). You'll need the following size o-rings (at end of message) they are avalible at Pep Boys under the brand name Metric O tite, just simply take apart the booster and replace all the o rings. I know I had to look for a better fitting one then the "2mm 5mm 9mm" size O-ring but I dont remember the size.

Once you get the black plastic part that holds the spring in, there is a piston inside there, and another piston inside the pistion, you'll need to get the large piston out to get the small piston out. to do that just simply unscrew the part where the brake pedal attaches and push it out, then tap the larger end of the piston on a flat surface and it should just pop out.

If you need more info email me.
