I have a 1968 Mustang with power disk brakes. I'm thinking of converting it from power brakes to manual brakes. What would be involved? The firewall has the big hole in it for the booster. Has anyone performed this conversion?

I would imagine the hole is the same size for both.

Your pedal carrier does not have the captive nuts for the MC bolts to go into so you would have to use bolts with nuts on the back or swap out the pedal carrier. You may want to do that anyway since a power brake pedal carrier and the power brake longer pedal are worth a lot more than the non-power brake set-up to people going the other way with theirs. You would of course have to block off the vacuum port.

Suggestion: pull the entire pedal set-up and MC and booster and sell it as a unit, then buy the cheaper manual brake set-up pedals and a new MC.

Not sure on the '67/'68, but on the '69/'70, the firewall hole is in a different location for a manual brake car vs. a power brake. You may have to "relocate" the hole.

Otherwise, it's as dustyrelics said.

You will definitely want to change the pedal, and I would recommend doing as he says, with getting the manual brake pedal hanger. Trying to put an MC on with nuts and bolts will be a Royal PIA.

Welcome to the VMF !!

The swap should be straight forward. As the others suggested, it would make life a lot easier if you picked up a new pedal support made for the manual brakes and a matching pedal (manual/automatic tranny pedals are different as well). Other than that, pick up a manual M/C from your favorite local parts store (drum/drum or disc/drum), plug the vacuum port, and you should be good to go. I'm sure others will chime in if I missed something.

BTW, I sent you a Private Topic concerning this swap. Good luck

Actually, if it's disk/drum, I would recommend using a '74 Maverick MC. It has a different bore and the pedal effort is a lot better than if you used a Mustang MC, since all Mustang disk/drum MC's are designed to work with a power booster.
