sorry, another drum power conversion.....1967 mustang.....

Post #1 by westu37 » Thu Jan 19, 2017 7:50 am

Hey all,

I searched the forum, but I can't find the specific info I'm looking for.

I have a 67 Mustang convertible, 200 with auto, 4 wheel drum, dual manual master cyl.

I ordered the small booster, and drilled/cut the firewall for install. The rod from the booster to the pedal assy does not seem to line up.

Of course the parts guy on the phone says it should fit....

Do I just meed the 67 automatic power brake pedal? or do I also need the pedal bracket?

The rod from the booster seems to want to mount closer to the pivot point of the pedal assy.

Any input is appreciated.

Wes

Some pictures of all the parts that your trying to use would be some help. That said generally a stock Ford power brake booster unit also used some different brake pedal linkage (as compared to the manual brake parts) to work correctly with the brake booster unit. Good luck :nod:

Yes, if you are using an OEM style power booster you will need the power brake pedal. Many of the non-OEM conversion kit boosters are designed to hook up to a manual brake pedal but it doesn't sound like you have that kind? I have done this conversion with an OEM booster and had to change the pedal.

Manual brake pedals measured 2.0" from center of pivot to center of pedal pin 1965-1970.

Power brake pedals measured 5.0" from center of pivot to center of pedal pin 1967-1969.

I'm also assuming that the power pedal assembly has to mount to the two holes that are the highest point on the pedal bracket? I ordered the power pedal assembly; waiting for it to show up. Yes my manual pedal is like described/pictured. I have the booster that is made by Master Power ( I think?). It is a small diameter and depth booster.

Yes, the 67-68 power brake pedal pivots from a 3/8" diameter bolt that goes through two holes up high in the support, higher up than the spot where the manual pedal/shaft are attached.
