It looked so simple at first!

There's a whole spiel in the FSM about setting the proper push rod length but it requires a number of SST's that no one has access to.

Trial and error mostly. I just set the master cylinder plunger cup against the booster rod and kept adjusting the length until the master cylinder sat flush against the booster without any pressure against the plunger and no slop from being too loose. It seems to work fine, I have good brake feel and no drag.

It's a good thing they used a rod that can be screwed in or out for adjustment, someone was thinking when they designed it.
