Brake judging

Re: Brake judging

Patrick.............that is unfortunate. Well I will beat the dead horse one more time. Of course the knowledge base moves faster then the Guides do. Thats not the point because I enjoy studying............for example I can replace my calipers if I don't rebuild them with new castings of which can be purchased with Delco Moraine casted into the caliper or the same caliper without the name casted. Guess which one is more expensive but the same casting??? So if I go to the Guide and it says they are judging color then what the heck are they looking for a DM casting for??? So what you are telling me is buy the more expensive casting because someone might ding me for originality even though the Guide says otherwise???? If thats the case this is what is wrong with this org.

If you choose to build a car according to a "guide" you will be sorry and your wallet will be lighter....especially if you're working on a 63-64.

Re: Brake judging

GM castings are no more expensive than any others. In fact, you will have to look hard to find a casting that is not GM, or at least not new GM reproduction (same molds being used). So, I'm not sure why you are concerned about cost. The brand new ones might cost more, but once an original is rebuilt there is really no difference between new and used.

Call one of the brake suppliers, ask for the correct casting for your car, install. Done.
I find it's often less expensive to get rebuilt ones than to go through the hassle of rebuilding them yourself. It's even better if you can bring your cores to Bloomington or Carlisle to get the exchange $ rather than ship them.

Re: Brake judging

Addendum - ask them to paint the calipers black. It's usually a nominal extra cost, if any.
However, I almost always will properly repaint them with black caliper paint as available at the local parts store. I find that the black applied by brake rebuilders is quite thin and allows rust to form quickly.

Re: Brake judging

I'm not making this up. Brake supplier has new Delco o-ring calipers for $200/ea. The same vendor has new calipers without the Delco name in the casting for $130/ea. Appears to be a version of the same casting. They also have rebuilt Delco castings with o-rings for $115/ea with a core charge. I will probably go the rebuilt route but you get the point. NCRS needs to back off brakes and stay with judging what is currently in the Guide. Its that way for liability purposes.There is no new knowledge regarding brakes that justifies deductions for originality other than what is currently in the Guide.

Check with Vette Brakes as well as Lonestar Caliper.

Unfortunately the Guide for your car is dated and not very comprehensive compared to the newer guides.
I don't suspect that the standards will change with regard to calipers.

It is best to paint them black yourself, as I doubt any rebuilder will leave the exterior machined surfaces free of black paint. But then you guys who have been down this road will know better than I.

There were actually 3 different series of caliper castings-----65-E67, L67-~72, and ~1973-82. They are 100% interchangeable but there are different casting numbers and other nuance differences.

1965 to E67---casting numbers 546xxxx

L1967 to ~72-----casting numbers 545xxxx

~1973 to 1982----casting numbers 547xxxx

I don't know if this is judged but, theoretically, it could be.

Re: Brake judging

Thanks Joe. I will see what i can do to maintain the pertinent series.

Re: Brake judging

Joe........ Lonestar said they will honor a request for a specific casting series # so really appreciate the heads up. They said if you don't make a request you get what is pulled off the shelf.

Re: Brake judging

Looks like I was able to answer my own question. 2 points for caliper color(black) and 2 points for rotors and hoses. Not a big price to pay if its just cosmetics. Everyones originality objective is different when it comes to performance and safety.

I look for color, DM logo and if see something suspect, look at the hoses and if the hex metal ends are plated gold dichromate are whatever plating color that is. Lonestar got a batch of an alloy hex crimped ends and I saw them on a Pace Car. It was obvious the calipers had been changed so a chassis judge gets nosey. Starts looking at other stuff! I have always considered hoses a safety item. But if its a Bowtie candidate...well you know the story there.

Re: Brake judging

Not defending the judging guides, but the A Model guys made many major revisions 60 years after the last car came off the line. Updates are a natural evolution. Nit picking is for another story.

Sounds like it to me...........change is good just tell somebody
