Brake lines and zip ties - Subaru Enthusiasts Car Club of the Sierras

dknv · 2004-07-07, 02:28 PM

A novel idea -- but I don't think I would ever try it myself.

Good lord.

That might be useful for abrasion resistance, but there are better ways of doing even that...

sperry · 2004-07-07, 02:55 PM

good lord.

I guess that's supposed to be legal in stock classes? But what about passing saftey/tech inspection?

So if you zip tie all the way along why couldn't you just rig up a steel sheath for the hose. I didn't read the rules but this seems to push them.

You can keep your stock hose but have still basically have steel braided lines?

Why your at it, why not have a custom made sway bar that attaches to the stock one some how.

pft. perfect opportunity to use pink zip ties, and the guy goes with black.

Kevin M · 2004-07-07, 10:06 PM

I swear this got debated to death back on nasioc or i-club last year. Austin, what do you suppose would happen if the gap between 2 of those zipties got to be, oh, 3/8" wide? And then you sent 1500 psi down that rubber line? Nothing good, I can imagine.

Bah SVX owners aren't real Subie folk, they don't appreciate the STi image.

I think it's because we spent the same 6 years at Cal Poly making fun of all the same dumbshit cars in SLO. And the normal response: "good lord.

"

My guess would be nothing, because they're probably doing nothing to restrict line expansion in the first place. It's not like OEM rubber lines blow up like balloons when you step on the brake pedal, it's a pretty minor amount of expansion... probably under the amount of slack present in a zip tie that's "tight". If someone wanted to actually test it they could just take a good set of calipers & measure the line diameter under 0 & full pressure, before and after zip tie application.

I'm normally a fan of zip-tie engineering, but something about tossing them on brakelines gives me the willies.

Besides, if the zip ties don't restrict line expansion, what the hell is the point?

Nick Koan · 2004-07-08, 05:21 PM

well according to the original thread, they were there for brakeline expansion. to get around the auto-x rule against steel braided lines. Sure the zip ties probably aren't as strong as steel braids, but it may offer some advantage over normal brakelines.

That's what I was wondering too.
So, if I ever autocrossed the old red legacy wagon, maybe I'll try that on it!

If it's 10 years old, you can use steel lines.

'splain yerself! I don't remember reading that rule.

Nick Koan · 2004-07-09, 08:54 AM

from the thread linked at the top

Quote:

It's a long story Mark, but since I want to compete in G-Stock SCCA AutoX next year, vehicles manufactured on or after '92, can't use steel braided lines. This is the only way to get around that rule while still keeping my car 'legal'.

If you want to read more, check out this thread: SCCA Solo II Stock Class

and from http://moutons.org/sccasolo/Rules/stock.html#s13

Quote:

13.6 Brakes

1. The make and material of brake linings may be changed.
2. Substitution of clutch and brake hydraulic lines with solid metal or braided metal is allowed on all cars manufactured before model year 1992.
3. Alternate brake bleeder fittings such as "Speedbleeders" are permitted They may serve no other purpose.

now, I'm not a big auto-xer, nor do I know the rules really well. I'm just cutting and pasting stuff from the SVX thread.

Kevin M · 2004-07-09, 12:03 PM

Ops, 12 years old now I guess. Applies even to the stock classes.
