I'm attempting to upgrade the single bowl brakes on my 65 FB. I have purchased a new differential pressure valve, and a new master cylinder, the master cylinder is for a 67 / 70 Mustang with manual drum brakes. The pushrod measures about 5/8 of an inch shorter than the one in the 65 master cylinder. The old on just fell out when I removed it, so I dont think that I can use it over. Won't this shorter pushrod affect pedal height and travel?? Any suggestions

I still have not done the swap but I know from reading previous posts people usually re-use the old push rod because it is longer. You might have a hard time removing the short pushrod from the new master.

Yes,

Use your old pushrod! I wish I did, don't have much pedal travel 'til it hits the floor.

I agree with Steve, use the old push rod. But look at the top of your brake pedal arm and make sure you have a brake stop that keeps the pedal from pulling forward to far. The 67 push rod has a clip on the end that keeps it from pulling out of the master cylinder. If you use the clip, make sure you are ready to install, because the push rod is a bitch to get out with the clip on it.

Wish I had used the old rod as well. I don't have much pedal travel either. I did gain back a little by replacing the return spring under the dash. Not an easy swap however.

Anybody thought about just welding in a .5" of metal?

Jas,

I thought about it, but you'd still have to pull the rod out. And it is one part that I wouldn't ever want to see break. I saved the old rod, so all I have to do is change it. Someday......

You would think that someone like SSB would jump on something like this and squeeze an extra few $$$s out of it.

For those people who have used the late model MC do you still have thi same problem?

i just did the swap over on my 66 coupe, installed a 67 manual drum master cyl, used the old brake block, ran the rear brake line directly into the master, worked fine, i removed the push rod from my old single bowl master and used it on the 67 dual bowl master, worked fine and i have a good brake pedal...
