Do a search here on the forum I tought plastic was a neat way to go but if you read up on it you will think different. Think about what happens if you blow a oil line or anything that would cause a fire at speed it melts the brake line now your on fire and can't stop. maybe it would never happen but don't know if its worth the chance steel is not that hard to deal with.

I have personally seen 2 diffrent cases of failed brakes during emergency stops,both times from a guy who swears by the nylon lines!!!Im not a believer in them.

The safety aspect doesn't worry me... the only fire I've ever had resulted in having steel lines when my selenoid broke allowing the battery cable to flop over and short out on the brake line which melted the line resulting in an eruption of flames from brake fluid all over the headers. Long story short: car on fire and no brakes. The way I see it freak events are going to happen no matter what.

With that said, my last car was plumbed using plastic for the "ease" factor. I won't be using it again. I mean, I don't have a problem with others using it, several folks on here swear by it, I just personally didn't like the feel of the pedal with it. With this heavy of a car I just like the steel. The stuff sure was nice to install though. ;-)

I have a couple of buddies who drive modifieds and use nylon brake lines and swear by them. They want the weight savings (every little bit helps). They never have had a problem. I wanted to use nylon so the plumbing would be easier and quicker but in my class (factory stock) we have to use steel.

if it ain't fun, then don't run

I saw a mod blow a motor at ACS and he was using plastic lines, well schrapnel flying out of the motor cut the lines and when he tried to stop, no brakes, plus when he was pumping the brakes the fluid was feeding the oil fire on the motor which by the time he coasted to a stop there was a pretty good fire burning. Of course its your choice, but whats your safety worth?

I know the incident Bill is talking about and it made for a good picture thats about it. The driver was lucky he had a good fire suit on it burnt the leg of his fire suit. I wouldn't ever run plastic lines.

the plastic brakes line vs steel is the same type of argument as a 3 speed vs a powerglide...both have their strong points but in the end both are good choices. its just up to drivers preferance.

I know better than to reply to this question....but I don't always DO better, so here

First, if you do a search, you can see where this has been debated many times.

In the past, I have said that the lines were junk.......Now I'm going to do my Kerry imitation and change my position....

I think they are GREAT. 1001 uses..... You can use them for the water line for your ice maker....use them as "krazy straws" for the kids....straws for a remote water jug during long races......a fine water level...arts and crafts.....

Anything,everything.....EXCEPT BRAKE LINES.

I have personally seen three fires caused by the plastic lines.......Two due to improper due to debris breaking the line........In all of these fires, the drivers considered it a "freak accident"........In my opinion,they were all a logical conclusion to a poor choice of materials and routing.......NOT an accident.

Now, there are those who have used them for many years with no problems.......The key here is proper routing.....

If we completely overlook any saftey issue, (because no one thinks bad things will happen to THEM) take a look at it from the performance side......

You will be giving up some amount of pedal travel and firmness by going with the plastic.......You will have LESS STOPING POWER vs steel lines.......This is a fact....there is no way around it.

The only so-called "advantage" of the plasic is ease of installation......and a very small amount of weight.....(btw, the fittings are heavier)......

Steel brake lines for me......

Good Luck,

I've used both, plastic lines are mushy, IMO. I hated them.

Steel lines aren't that hard to install and they work 648 times better.

I tried plastic on my street stock and the heat that the manifolds put out will make the lines mushy. You can't get them far enough away. I had 3 failures in 10 races and the fittings to adapt them to the calipers are a pain in the **** (leaks). I now use all steel and stock rubber hoses. Don't believe the **** about stock hoses not being suficient for racing. They work fine and never leak which is more than I can say about stainless hoses. They have to be adapted to calipers also and that is where they generally leak. IMHO

When using plastic lines you should use stainless braided to go to the calipers w/ #3 an fittings, no leaks.

when we built our 2 cars this past summer we thought about plastic because we had the notion brake lines were going to be difficult but we bought steel lines and fittings at the parts house in the sizes we needed and both cars went together in hours not days!!! its not as dificult as you think if you can change front spring you can do it and piece of mind steel over plastic, not just fire but having brakes period.
