Well, we upgraded the brakes on the car with a better master cylinder. I got the "safety valve" below the master, and the line lock below that. Had to make several lines to up grade. I had a 0.920 bore master on the car but the pedal went 75% to the floor before hard braking. So, that came off and went with a 0.975 bore which brought it up to mid travel, which is pretty much normal for everybody's car.
I might add that there is so much mis-information about dual masters and how they work. Without that "valve", what ever you want to call it, you still have a single point complete failure of brakes. You have to have that valve to cut off the front/back, which ever has failed or leaks. AND, that only works when there is a relatively sharp change in pressure from front to back.
Lots of racers and street cars have a dual master thinking they have a "dual" system, but not without that valve.

What exactly is the mc for? What about the valve? I need to change the system on 65 Coronet! I got to get back to you on the master. The valve is from a 74 Dart. The valves I will call reasonably universal if you get one for your system, drums back, discs front, or all disks. Those masters from about late 70's to the 90's look ALL THE SAME. But the bore size is different, and the actual bore may also be different from what the parts book says. That .902 bore is stated as 7/8", but that does not translate over (.875). I think the .975 was listed as 15/16, but that doesn't translate exactly either. What is a little surprising is the pedal travel change in the .073 bore size change. Edit: O'reilly's part number NMC11257 and the same NMC1983. I believe this was from a Dodge Dynasty mid to late 80's. Bring your caliper when you go, manual brakes you want about an inch bore.

The Chevelle is getting a lighter transmission that will save about 35-40 pounds and let the old man driver shift only once. Hope it helps with consistency! Attachment Deleted

Also adding something special for the Mopar and Hemi cars.........but the forum can't load any more pictures so you will have to guess and wait until next May.

Hey, good for you Jerry! That power glide just might do you right.
Its funny, 'cause I remember back in the day a friend bought a nice used '66 Chevelle with a 396! He was all puffed up about it until asked what kind of tranny it had. Completely deflated, he said "powerglide". Course to the rest of us, it was a powerslip tranny. Funny how things completely change, eh?

So Jerry, what you are saying is that running Mopars in general, especially the Hemi cars, you are too excited running down the track, and need to shift one less time ? I remember the rage in Bracket racing many years ago was to run a Glide in any brand car plus put a 2 bbl carb on it. Maybe Damon could work his magic and cut your 8 barrels down to 2. Having run early 70's GM cars most of my life, I have popped a couple of brake lines, the valve is called a proportioning valve on them, and they do work, they will close off the leak side with a valve as soon as the pressure goes away, so you have front or rears, whichever, not real strong braking, but at least you have something. That is one awesome thing about us running on the big 1/4 mile tracks, plenty of shut down. I have also popped brake lines on big trucks that have a single master cylinder, you have absolutely nothing, except the emergency brake. Going to be a long time till the Nostalgia Rendezvous in May. Hopefully see some of the Victory Family at Clay and Rosie's Christmas Party December 1st.

Polarpirate, I (as you say) popped a valve on my son's beater truck when the front pad came out (yeah, how does that happen?). Ya got brakes, but very poor. On my signature street rod (since sold) I had a dual 68 Plymouth master, without a valve, that went to heck. And, no brakes. That is how I found out about "the valve". Did a lot of research since then.
There is a lot of street rods and racers out there with dual masters and no valves that just don't know. Which is why I brought it up.

Hi Tom, miss hanging out with you guys. I love harassing Jerry, all in fun, of course. Since we are on brakes, anybody out there that has older brake lines on their car, maybe should check the lines under holders/brackets, where dirt etc. collects. That is where I have seen leaks on almost every vehicle I had to replace a line on, they hold moisture and start pitting, then pop. Kind of like how body trim holds junk then rusts under the trim.

Working on a friends sure grip that turned out to be tore up, I found an interesting, yet worthless fact. The axle shaft spline and diameter is the same as the 727 output shaft spline.
Yes, interesting in that they have the commonality, yet worthless 'cause what does it get us? Carry on.
I have a picture of an axle gear on the output shaft, but can't load it due to web is full.
