Steel is more forgiving if you pick up track debris and for cleaning your car, I have also been told that the plastic will expand in high temp areas ( close to calipers ) giving a soft feel pedal.....we only use steel but I could see how the plastic would be much more simpler to work with.

Speedway will sell you a kit with steel line, connectors and four braided brake hoses for $99. Hard to beat that price.

I think its like the helmet rule. If you have a $5 head then buy a $5 helmet....

Put whatever you want on, I can only tell you this. I have run the plastic brake line kit from Speedway on my car for 4 years. I have broken the lines twice , once the brake caliper mount spun and ripped the line out, once it got pinched in the rear spring and smashed. I have melted the clutch line on the header pipe, but that was after we forgot to tie the line back into place after a trans change.

Wow ,lots of pros and cons....the reason I asked the ? was because the guy I am getting my parts from only has plastic in stock ,my prefrance is the longacre brake kit ,I have used it in the past and it was realy easy to install......I dont think weight is the isue here reliability is what I am after.thanks for the replys I think I will order the longacre kit.

I can see where the plastic would be easier to work with to a point, but how hard is it really to run steel? I have seen plastic lines get crushed, melted, cut,leak etc. I watched a guy coast around the track once after his engine blew and caught on fire. Burnt through all the lines to the front and rear brakes. He couldnt stop and just had to coast all the while his car is on fire around him. There were a lot of cars trash there plastic after that.
We have always run steel and really once you get the lines on the car once you never really have to mess with them again. We've never had to replace steel lines, just braided here and there.

Ran plastic on MANY cars and have had NO problems. Several trips to the wall and two fires and have not had a regret. Use your head when running the lines, we run braided lines from the master cyls down to where they can enter the chassis then we run the plastic in a cheap small fuel line to where it needs to come out for the tire.
The complete setup will weigh around 10lbs, alot lighter than steel and you do not need a flairing tool, bender or tubing cutter.
THE BEST PART is I can replace ANY line on my chassis in under 5 minutes and cary enough tube to do the complete chassis in a ziplock sandwich bag.
Even if you loose the front or rear lines in a fire you still have the brakes on the other end of the chassis

In regards to crushed lines, pinch a steel line and hit the pedal if it dosen't lock up and stay there it will heat up and cause the pressure to stop the wheel. We have kinked the plastic in a small accident and it pops back when removed from the pinch and you can smack it with a hammer and the dent dose not shut the line off like steel will.
We will not go back unless the rules change, beside you can get enough for a whole car for $30 with fittings.
