wcbjr Posted March 23, 2006 Share Posted March 23, 2006 Okay, I just want to get this random though thought of my head once and for all. When I picked up my RB20 front clip a while back, the brake lines were completely zip tied (like 20-25 per line). They apparently were using them as a very cheap alternative to steel braided lines. Now how much do the rubber lines actually flex? How much would zip ties help? I am looking for mathematical answers, not the "that's so stupid, that won't work" that I am already thinking. I forgot what I was supposed to remember. Link to comment Share on other sites More sharing options...
RobY Posted March 23, 2006 Share Posted March 23, 2006 no. You would actually break the lock on the zipties if brake lines flexed enough for zipties to make a diffrence. Link to comment Share on other sites More sharing options...
wcbjr Posted March 23, 2006 Author Share Posted March 23, 2006 Math please. What are the forces on the lines? I am already thinking what you said. I forgot what I was supposed to remember. Link to comment Share on other sites More sharing options...
Xenonk Posted March 23, 2006 Share Posted March 23, 2006 rubber lines should actually have a stainless steel jacket over teflon tube line for some OEM types.. it's just that the rubber jacket is not fancy and clear like the Techna-fit lines nylon jackets You can always cut a spare OEM line laying around to find out Keefe Link to comment Share on other sites More sharing options...
RobY Posted March 23, 2006 Share Posted March 23, 2006 Math please. What are the forces on the lines? I am already thinking what you said. Yout talking a few thousand psi contained by the brake lines during HEAVY braking. A set of zipties arent going to do anything to contain that. If you could somehow get them tight enough to compress the inner tube of the brake line as soon as you stepped on the brake it would be reasonable to beleive that a few thousand pounds of hydrualic pressure would snap the lock on a zip tie that are usually rated for 30 lbs of pressure. Keefe is right about brake lines being braided. Usually they are braided with some sort of material and able to resist many thousand pounds of pressure. http://www.parker.com/hpd/images/styles/HPD-421.jpg Link to comment Share on other sites More sharing options...

Not to mention the strength of the underlying rubber hose. I forgot what I was supposed to remember. Link to comment Share on other sites More sharing options...
RobY Posted March 23, 2006 Share Posted March 23, 2006 well try it see how it works out. You can always cut them off. In my opinion it wont make much of a diffrence. Nylon zipties are probably going to flex alot more than a multi layer braided hose. Link to comment Share on other sites More sharing options...
Wangspeed Posted March 23, 2006 Share Posted March 23, 2006 Zip ties to hold them in place, or rather, out of the way, are excellent, just make sure to cover the brake lines with rubber if there is line -> metal contact anywhere, like a control arm, etc. Zip ties to attempt to firm brake pedal is pretty absurd.

Warren +1 cut/split some small diameter silicon hose and wrap the brake line areas where it may contact with metal and use zip ties to hold it in place.
