This is what I've posted on M/R concerning my manual brake swap, thought it might help out here also. I've been watching the manual brake post here and on other sites very closely because I'm doing the same thing. I've seen alot of the same questions keep popping up (including some by me) and I thought some pictures may help clarify things. I'm not a brake guru. I hoped to have this finished up this weekend, but been called into work a few times. So here's what I've got so far. Here's the brake peddle from my parts car with power brakes, the upper hole (above the pushrod stud) is the hole thats needed for the manual brake pushrod to have the proper leverage. Here's my brake peddle with the new stud pressed in (I added a bit of loctite for peace of mind) The old power brake stud could be removed, I left it. Opening left in firewall after removing booster Here is the adapter plate I had intended to use from a manual brake s10. Notice how the mounting holes are distorted from the bolt torque. Instead....I'm using this aluminum adapter plate. Notice it has a integeral cup to retain the pushrod. More on that later... The opening in the firewall need some minor trimming when a pushrod retaining cup is used, not much, took about 2-3 minutes to open up the upper portion of the opening about 1/8", I test fitted the s10 type also, that cup size is larger and would have required even more trimming. Thats it for now. Next weekend I hope to finish up and show some pictures of the custom pushrod and Manual master bolted up. Special thanks to Malibudave1978. He's helped me get this project headed in the right direction. The guy knows his stuff!!
