guys
what is the benefit of stainless steel brake lines ? do i have to do both front and rear, or will i be ok with just front ?

also what is the best brake fluid for my car ?
i notice i get some fade and im not sure if its from the lines or maybe i boiled the fluid again ?

 

Upgraded steel braided brakelines reduce the flex a stock rubber line gives under pressure. The lines will give you a stiffer pedal feel and basically less "mush". The lines are teflon lined with a steel braided gel coated constructions. The lines have CNC machined ends. They will last longer then your stock ones, never cut and improve braking. It would be best to do front and rear together. I also recommend the Motul RBF600 brake fluid which is a DOT 4 synthetic. This brake fluid can handle much higher temperatures and will not boil. These 2 mods alone will greatly improve pedal feel.

Ditto to above, hey any more of those pads, give me a shout!

 

how many bottles of the brake fluid do i need?

 

does Porsche us SS lines on the cup cars?

 

Who did you hear that from

 

to do all 4 wheels I would say 2 but get 3 to be safe.

 

the only actual "benefit" that I know of and I am not a mechanic just a driver is that the SS will protect the lines from getting cut especially in the enduro races we do. you will not "feel" any different, no way the rubber "flexes" that much, urban legend.

best brake fluid is Castrol SRF, motul next.

fade is your pads (hot gas layer) or fluid boil=air in lines.

addressed by new and better pads, and fresh better and bled brake fluid. then RS Cup ducts front and rear.
soft pedal is NOT from your lines.

above is my learned opinion only.

tom, dont make me send you a set for free to prove you wrong if you notice it, pay for them, if not, make them into a necklace.

 

I used SS lines in the past, I stopped on my last two cars. This article was a big reason as to why. Keep in mind, my cars are mainly street driven with the occasional track day.

And the reason why I asked what Porsche uses on the cup car. I also agree w/ Craig on the Castrol fluid, great stuff. The Valvoline SynPro isn't bad for double duty cars either. Changing/bleeding brake fluid is something that is very often overlooked.

 

I usually agree with Tom, but not this time. As the rubber ages, it gets softer, and it can flex. I recently replaced the pads and rotors on my daughter's 99 Passat, and the pedal was still soft until I replaced the rubber brake lines, too. I had already changed the fluid.

I have SS brake lines on my 996TT, and have used Ate Super Blue, Motul 600 and Castrol. Currently using Motul 'cause it's so much cheaper than castrol, and I've had no brake fade issues. We'll see how they do at Road America next month. Never been there, but it's a really fast track with a reputation of being hard on brakes.

Jon, no problem that's what the forum is for for us all to share what we think and feel ourselves. My car is track driven and my comments pertain to keeping things in best condition or replacing them as failures on the track tend to cause bad things. So I would submit that if two new TT's driven off the showroom with all brand new stock brake components but one with SS lines one with factory, I myself would not be able to tell the difference as someone with less of a meat foot may be able too? That fair??

Jon, as for Road America, make sure you run the RS Cup ducts!!

 

are you doing just spirited runs? or road course/track?

If track than get the fluids changed asap especially if you feel the pedal get soft. i personally didnt "feel" the SS lines. They work when your at the track braking hard over and over again. You dont really feel them. I agree with Tom. Usually soft pedal under strenuous repeated braking is due to Heat soak on pads, and boiled or almost boiled brake fluid.

I use motul 600. 2 to 3 bottle for a full flush. Youll have some left over. I once boiled my fluids at the track. Luckily it was a cool down lap... Lost brakes completely. Scary!

If you are just driving spirited driving i dont really know how the SS will be that beneficial but for a cheap mod it doesnt hurt. dont expect much from it though. The fluids do for sure at least once a year if their is no track time involved. If track is involved people usually say once before every event.

 

You have to take into consideration that every track you go to the car will have a very different set up etc. It's easy if you ride the same track day in day out, you can dial in settings and know how the car is going to perform/usage etc. My local track is brutal on brakes and tires, and you will find other tracks like Oulton Park will give the suspension a serious workout! I have always ran braided lines as I will not take any chances on brakes full stop, it was only a Month or so ago that I ran my best lap (57 sec) at knockhill overtaking 2 RS's at the time (big cheesy grin on my face) to find myself nearly binning it at the end of the straight, not boiled my fluid but overcooked and running partially glazed brakes, lol, if only you could have seen my face then
