9/29/23: Continuing on installing the booster, I bent and flared new lines from the MC to the proportional valve, then remounted the booster assembly with the push rod so I could measure the amount the rod needs to be shortened. I estimated, if I shortened it by an inch, it would leave plenty of room to adjust it.

Having a lathe made shorting the rod easy. I cut the bulk off with a wafer wheel then cleaned it up on my lathe. I ran a tap to clean up the threads and screwed it on the booster. It lined up perfectly with plenty of adjustment.

9/30/23: I finished the adjustment on the rod and tightened it up. The instructions say that there should be about a 1/4” of movement before you feel any resistance. I couldn’t really determine what resistance they were talking about, so I left it as is for now.

I want a new access hole over the new MC for ease of maintenance so I removed the carpet and the felt padding to access the floor. Not such an easy job because I didn’t slit the mat at all when I installed it, preferring to remove pedals and cut the holes to fit. I ended up removing the parking brake, accelerator pedal. When it came down to the clutch a brake pedals, I decided to slit the mat as I wasn’t going to remove them.

My floor needs to be replaced so a previous owner installed some crude patches on both sides. I needed to remove the drivers side to get to the original floor. I never removed the patch before and it confirmed that the floor really needed to be replaced. I am not going to get into that can of worms right now so I cut my access hole, fabricated a temporary cover then reinstall the patch.

10/3/23: Today I bench bled the MC then finished assembling the proportional valve to the booster and new lines to the MC, hopefully for the last time. I started running new brake lines. I ran the rear line first as it was the most challenging. I opted to split the run in two as it would have been really difficult to form it all in one piece especially since I was laying on the ground. If I only had a lift!
