I lost that foam seal by the fire wall too. I just did this upgrade with partsd from NAPA, under $200. I used a peice of copper pipe foam insulation, works. I have to bleed them again, but big improvement. the peddle seems to have alot of travel, is this right? I pulled the old MC and Booster off, and let the brakes completely drain, then installed the new MC after bench bleeding, and let it gravity bleed. any hints or tricks would be great.
