    Back when I had the 2001 V6 master cylinder, 13" Cobra brakes, and a Booster Dewey rebuilt booster, I could only get 925 psi to the front calipers which would not lock up the brakes. I removed the booster, changed brake pedals, got over 1,300 psi at the calipers, and the brakes have worked perfectly since. Because of the increased leverage of the manual brake pedal, locking up the tires is quite easy. I have never once wished I still had power brakes. More room in the engine bay is an added feature.

     
    Good info- so I believe I should be able to use my v6 mustang master cylinder. But get a manual pedal. Does that sound right?

    That's what I did. I made an adjustable push rod to fit.

    Pretty sure you'll need to buy/fab the plate between the firewall and MC.

    Where were you able to source a manual brake pedal? I gave mine to a friend when I converted to power brakes. Do you know if 1967-1969 pedal will fit? They are all over.

    Re: Brake issues

    For 65-66, the manual and power pedals are the same. When I swapped to 4 wheel power disc brakes, I moved the pin down to get the ratio change.
    I ground the weld off the back of the pin, and drove it out with a drift, re-welded it into the new location.
    If your original pin was cut off, MS sells a new pin. You should be able to change your pedal back to how it use'ta be.

    Re: Brake issues

    68-70 manual brake pedal will work in 65-66.. offset is a little different and foot contact plate is wider, but it can be easily cut to fit. The offset should not matter.
    Power brake pedal 67-70 is different and will not fit 65-66 pedal support.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Thank you , update- I think it may be a differential issue causing a rattle- I took it out and is at the shop. He will look it over and fix if needed. Going to have it narrowed a bit more while it’s there.
