I have a 66 mustang that has drum brakes all the way around. I was wondering if the 1967 mustang power master cylinder that came off a all drum brake 67 will botl up and work on my 66?

I did this conversion about a year ago and love it. Not only is the dual MC safer, but will increase braking performance.

I have a '66 with all drums no power brakes. I converted to power with a booster from NPD and a '67 all drum MC from autozone. You can order it online and save yourself some money over what is charged in the vendor catalogs.

If you are doing a '67 MC upgrade without power, you will need a non-power MC, if you are going to upgrade to power (and I strongly suggest it!) then get the power all drum MC. The front bowl will connect to the rear lines, and the rear bowl (closest to the driver) will connect to the old distribution block for the front lines. There's another guy on here doing the same thing, i should take some pics and post them.

For the brake lines, there are kits you can buy but I ended up taking my new MC down to the auto parts store with a few of the old lines to match everything up. I ended up needing an adapter screwed into both MC ports for the lines to work. I bent the lines myself. It wasn't too difficult, just go slow and check & recheck!

I have the 1968 Mustang Fastback with drum brakes all around. My Mustang had a manual transmission and now has an automatic transmission. Do you know if the brake pedal will need to be changed to add the master cylinder and power booster?
Thanks

Do you have the same brake pedal as you did with the manual transmission? If so, I would assume you need the booster that fits that pedal. When I bought my booster from NPD, I still used my original brake pedal without problems. However, I think this is not always the case on the 67/68 cars? Not really sure on this one.

Perhaps someone else here knows and can shed some light on the subject. Or, do what I did and call NPD NPDLink | National Parts Depot
tell them what you have, and they can help you out. They were really nice when I called them!

Here are a few shots of how the lines are plumbed on my '66. Note that the front bowl has a line going to a union that then goes to the rear brake line. This rear line was unplugged from the distribution block already on the car, and a plug was installed. The plug and union both came in a kit from CJ Pony Parts.








The rear bowl line is now connected to the dist. block. It connects where the old MC line did. That is to say, the old MC had a single line connecting it to the dist. block. With this rear bowl connected to the block, the block now becomes a dist. block for just the front brakes.

Hope this helps y'all. Most people just do the front disc conversion, not a lot of MC only or power upgrades for front drums out there.
