Brake Pedal Issue - Help!!
I am switching my '73 from an auto to manual. I have the pedals installed and I went to install the brake booster. I need to move the brake pedal about 3/8" toward the floor at the clevis pin in order to get it to line up. This seems to place the brake pedal much lower than I thought it was with the automatic. The clevis doesn't appear to have any adjustment. With the pin installed the brake pedal is much lower than the clutch pedal, and more aligned with the gas pedal. It's also about 3/8" away from the rubber stop for the brake pedal. Is this right or do I have something messed up?
Thanks,
Jim

I just completed this swap in my 75 and didn't run into that problem. My pedals are used original, not after market. The bottom top surface of the brake pedal is about 7 1/2" from the floor with carpet.
Good luck, Dave

Thanks for the feedback. I measured the lower right corner of the brake pedal perpendicular to the pedal and right to the angled part of the floor I get 4.75" without the clevis connected and I get 3.5" with it connected. Without it connected I get about 7.5" from the lower right corner of the pedal to the flat part of the floor. I'm think the pedal is getting pulled down too far when I install the clevis pin, but I don't see where I can do any adjustment. I converted from manual to power brakes and the clevis for the power brake booster doesn't seem to have any adjustment. It just bottoms out on the booster shaft. I don't think turning the shaft extending it.
I'm stumped.

Thanks, I was reading a couple posts on the forum and it seems like there is a difference in brake pedal height if it's a manual or power brakes. If it's power brakes, the brake pedal is apparently more in line with the gas pedal and lower than the clutch. If it's a manual brake car the brake and clutch pedals are more aligned and higher than the gas. This is the way my car is, which leads me to believe maybe it's ok. I don't recall when I connected the brake booster with the automatic brake pedal if I had to push the pedal down as bit to connect the clevis and in doing so, it aligned the brake pedal with the gas. I only road the car for about 5 miles before I decided to make the 4 speed switch so I just can't remember how the brake pedal aligned with the gas. I do remember I had to move the brake light switch bracket a fair amount to get it aligned with the new brake pedal. I wonder if I adjust the bracket back to the original spot I'll find it lines up with the brake pedal when it's now connected to the booster.
