Switching back to manual brakes help!

So my car, a 67 standard, came with manual brakes. I had a local shop put a Leeds power brakes kit and Wilwood disc brakes on the front. I was not impressed with the handling of the power brakes. I want to switch back to manual. Does anyone have a suggestion for a master cylinder kit with an adjustable proportioning valve that hangs under the cylinder? Has anyone done this conversion? Any suggestions? I have found Many threads on changing manual to power, but not power back to manual.

Anyone have any experience with this? The 2 reviews say they had problems with leaking.

" I have found Many threads on changing manual to power, but not power back to manual".

Because going from manual brake to power disc is a big improvement is the reason why you don’t find information going the other way. What don’t you like about the power disc setup? I’m thinking if you don’t like it over manual brakes than something is wrong with the setup or installation.

Agree, Post some more details about your power brake conversion and what parts are used. Might be able to sort out what issues your having and why your not happy with them. It could be as simple as missed or incorrect part for your system.
