Don, New brake pedal geometry

Well, I final got the new motor in and the cobra on the road again. I installed the new brake pedal you sent. I also install an adjustable proportioning valve. I am just glad to be able to say The new brakes work much better !!!!! The car stops quicker and with less pedal effort. I'm not sure if the improvement is from the proportioning valve or the new pedal set but I don't care. The pedal upgrade seems to have worked for me !
There is one small problem. The brake pedal is up a little too high, but, after careful study, I think I can move it back down a little without changing the new geometry setup. This will be one of those winter projects.

Thanks again Don- you da man!!!

Paul, I'm glad your brakes improved. I'm getting mixed reaction on the pedal. Some say it works and others say no improvement. What type of prop valve did you install ? I just received a brake system pressure tester so we are going to check the entire system and see what else we can find.

Don, the prop valve is the one by Wilwood. I have it turned out all the way, giving the max pressure to the rear drums.

Thanks again

Paul

Don, I have a similar problem with the location of my brake pedal. a couple years ago I changed my booster per your recommendation (which worked great by the way), but it brought my pedal a couple inches closer toward the seat. Any ideas how to move it toward the firewall and how far in front of the gas pedal should it be for heel toe downshifting.

dvcobra, I'm not sure why your pedal would have moved closer. The car calls for a 1974 to 1978 Mustang II booster and they were all the same. I have seen a couple of the boosters that the rebuilder had added an extra bracket that moved the booster away from the firewall which would bring the pedal closer to the floor. I'm not sure what to tell you about moving the pedal back where it was. I usually set the brake pedal about 3" higher than the gas. That way there is no chance of hitting the gas at the same time (which I have seen happen). Actually you can't change the brake pedal, you must move the gas pedal with the cable length.
