I have a friend building a 32 who asked me what the spacing of clamps holding brake lines should be. I said he had to much time on his hands. He said he thought there was an industry standard for correct spacing. News to me; has anyone heard of such a spec? Thanks, Tom...
Ok. I will be serious. Today cars are about ever 12". Some even closer. On an older car I would go about every 16" or what looks good. The more the better. The theory is that the vibration will work harden the lines causing them to break. A little bit of info picked up at anti-lock brake classes.
What ever it takes, and probably won't be even spacing. I've seen sections where they are 3-4" apart followed by 16" spacing back to 6
If it's safe anough for aviation it's safe for your car http://www.tpub.com/content/aviationmaintandmisc/TM-1-1500-204-23-3/css/TM-1-1500-204-23-3_16.htm later jim
Every 8" is what you have to do if you live in a country with regulations. Even without a rule to follow 8 inch is good. No rattle .
Your friend is building a '32 and can't figure out how many line clamps to use? Tell him to just use common sense and add clamps where he feels necessary. It isn't rocket science!
here is the formula to use: Length of the brake line, divided by the diameter of the line. Take this number and subtract it from the total length of the car, once you have done this weigh the car, take half of the weight of the car and add this to the number you already have. Now check the temperature outside, above zero add it to the final number, below zero, subtract it. Once you have this final number subtract you age from it. If it is less than 12, round up to 12, if it is more than 12 round down to 12.
you forgot to specify fahrenheit or celcius also windchill should be factored.does wind from east make difference?
I think this is an intelligent question, obviously some here can't manage to crawl out from under their rock and see it this way! I've always supported the ends, joints, bends and about every foot between and never had a line crack, break, or leak from lack of support. If you use the aircraft standard of 9" for 3/16 brake lines you won't be wrong.
