I have been taking my time over the past couple of weeks, but I have finally installed a Mitchell transmission in my '30 coupe. The transmission went in fine. The rear end went back in fine. Everything was going great. I was trying to finish hooking everything up today and found an issue with my brake pedal.

I put the brake and clutch pedals back on and hooked them up. I stepped on the brake pedal and it didn't want to move so I pushed harder. There was a loud bang and then the pedal moved. I released the pedal and it bound up again and again made a large bang when I pushed it hard.

I had my son push the pedal and I got under the car. What is happening is that the actuator rod (or whatever it's called) that runs from the brake pedal to the stop light switch is sliding under the switch's push button. The bang comes when you depress the brake pedal and the rod slips out from under the switch plunger.

I have no idea why it is doing this. I changed nothing when I disconnected the brake and clutch pedals. Another interesting note is that I had one of those aftermarket brake pedal return springs hooked up before I took the car apart. The spring had a lot of tension. Now, I threw it on just to see what would happen with that installed and it's like way loose.

Is there more than one way to install the clutch and brake pedals on the bellhousing shaft? Do I have them not sitting in the right position or something? I can't figure why it worked fine before and not now.
