After DW Cook gave me a little advice in the tech section, I was able to figure out how the proportioning valve works.

Rebuilt the M/C with a kit, opened up the proportioning valve to vacuum bleed the brakes and.............shazam!.................WE GOT BRAKES....................as good as they are going to get with a ZL1 cam.

Got a few things sorted out on the car, then bubba's work on the carb reared its head. The baseplate was glued where the idle screw threads in.

I've got a message into Eric to see if he has a nice baseplate for a 4053 Holley

So much for a debut at a little car show tomorrow

I'm in the process of doing some brake work to the car. After rebuilding the front calipers, I am not impressed with the brake fluid pressure or volume at the calipers when bleeding. I took the car for a road test and again, I am not impressed.

So, is there a way to test/check the distribution block as well as the proportioning valve? I know replacements are available. I would just like to keep the original parts on it.

Thanks!

Tim






Tim,

What is the code on the tab of the M/C? Looks like the same for 67 Nova with factory Disc? Code "DA"

Dave,

The stamping is really light. I would say the last letter is "T". The first, I cannot make it out. A "WT" master would have come on the car. Are the original stampings usually that light?

The way the bore of the master was corroded and the patina of the exterior, a person may be willing to speculate it is original. I'm surprised the M/C kit worked

Thanks,

Tim

Tim,

That is correct for 67-68 power disc Camaro's {WT}1 1/8 bore. The {AD 1&quot; bore} is for manual disc which is the same as the 67 Nova with factory disc. They are all hard to find!

Looks good to me on originality to the car Tim...great car!!!! [img]<<GRAEMLIN_URL>>/worship.gif[/img]

You might want to just send the master and proportioning valves to Whitepost. They did an awesome job on the original master cylinder and wheel cylinders in my survivior SD455. If you tell them in advance that it is a survivior car they will leave the outside finish intact.

Glad you got the brakes sorted out. Hopefully Eric will have what you need to get that beast running nicely again.

Eric rebuilt the carb.

..what did you call him?

The brakes are a different story. That would be Sal from American muscle cars. He's the
reason I sold the car after 13 years of ownership.

There was some &quot;JB Weld&quot; on the idle screw boss. My experiences with Eric have been nothing short of top notch. I believe someone else was in there since then.

Again, the brakes with a ZL1 cam..........pretty good!

Wicked sounding ride.

Wow what a sweet car and cool history
