I'll have to wait till labor day to really verify that I'm good to go but after having a very hard time bleeding the rear, I think the ultimate thing was the booster-mc gap. From what I measured it had nearly 1 5/16" to start with. I got a longer bolt and got it down to 1/4"

Please explain longer bolt, I'm not sure what you mean.

The adjustment bolt on the back of the booster rod, which activates the cylinder, was only like 3/4" in total length so I wasn't able to extend it out far enough to close the gap that I needed. I replaced it with a longer bolt in order to have it extend out farther. A photo would really go a long ways here, and who knows I might be doing it all wrong but I was really moving trying to wrap it up today and didn't snap any shots

ok here we go. I changed out this little bolt with one about an inch longer. this way it extended into the rod solid but then stuck out about an inch as well. I put a new nut and a lock washer on it to lock it in place

guys please somebody let me know if I should not have done this for any reason. I was just trying to close the gap up

Man I wish I had this picture 2 weeks ago when I was screwing with my booster. This bolt you are talking about, does it thread into the main rod that goes into the booster?
When I did my measurement I had about 8-9 mm gap between the rod and the piston. I couldn't for the life of me figure out how to adjust the rod to take up the gap between the booster rod a the MC piston. I ended up shimming out the poston in the MC. Probably not the best solution but at least it made my pedal better.
Where did you find a longer bolt? I'm still not sure I understand what is going on in the pic. Is it a threaded rod within the larger rod?

Curious, do you know what size MC you have Cell? I was told to go bigger, but also hear a smaller 15/16 MC would work better. URGHHHHHHH!

Yeah so the "Hydraulic Push Rod" is what's going to activate the MC. The small bolt at the end of it even had a little lock nut on it, so it looked like it was there to provide adjustment. I pulled the bolt and it was just a standard 1/4-24 bolt, so I hit the hardware store and got a longer one. I couldn't find the exact same head so I just went with a Fabory phillips head.

What trips me out is that with my booster and MC coming together I figured it'd at least be pretty close, but it had about an 1 5/16" gap, just wayyy too big. With the new bolt I set it to about a 1/4" and it felt way better, but now I'm just doing some reading and found an article claiming .020" to be the right gap, so it sounds like I still have a ways to go. Hope that helps
