I'll chime in here even though all the brake "experts" have already spoken. Recently swapped out the original rubber lines for some SS ones. Also switched from ATE to SRF. I can tell you that there is no perceivable difference between the 2 setups for street use. Mind you I have always run fresh brake fluid since I flush that twice a year. My pedal has always been firm even before the switch. On the track, I run Pagids and noticed the pedal feel is more consistent with the SRF vs ATE, but I doubt the SS lines made any difference. Just my 2 cents.

Hi

I fitted the SS brake lines and felt no perceptible difference in the pedal, my friend has a tip that has a rock solid pedal and the car is older with more miles than my old bus. I think that Steve W and Chris W are advocates of the original silicone lines, there lies no better recommendation.

I actually asked Joel about this a few years ago, and got a different response. He basically said it wouldn't make much difference, but for $100 why not. I change to SS lines when I did my last brake flush, and I also don't notice much difference.

It feels better that the SRF, rock hard pedal. (I am running RS calipers and Pagid Black Pads as a reference). I haven't run SRF in my car but have driven a car with the same brakes as mine with SRF.

I just spent the past weekend at Miller Motorsport park and did over 500 miles on the track and the pedal was perfect from the first to the last lap, no bleeding, no issues.... Endless fluid is superb,

Okay, thanks, Steven. So, you haven't run the SRF in your car and done a back-to-back "test"? There are definitely car-to-car brake pedal differences. Too bad I just bought five bottles of SRF.

my brake is super tough not at all like a mercedes or bmw

SS vs OE comparo aside... at this point in the life of the 993, replacing the lines is not a bad idea

Personally, I wouldn't track a 993 with the original lines

Sorry, no back to back in my car..... Hey there is always next year to try some Endless. Funnily enough the only time I bleed the endless is when PCA requires a fresh bleed of fluid, otherwise I would only be doing it once a year (if that)

This really is the best advice overall. Our cars are getting old.

When I replaced my lines I put on stainless ones, as I had a set from a previous project, would I have been happy with OE, absolutely.

Mark, see my post about my experience with SRF. I was quite happy with ATE and just decided to try something different this last time out. I'm not sure if the extra cost of SRF is worth it performance-wise, but I just saw a guy with a 996TT at the track boil his fresh ATE fluid and had his pedal go to the floor! In this case, the extra money would be well worth it compared to track time lost....

I can query a friend who was an IRL team manager. But I hear what you're saying from an engineering standpoint. In practical, real-world-on-the-track experience I was never happy with the large master/930 brakes with a 245 or 275 front tire on a 9" wheel. Maybe it's me. (It's better with the '73 faux RS and 225's on 7" wheels.) I can say I've driven 5-7 cars similarly set up to what my '74 morphed into, and I was never satisfied with any of the setups. Not all built by me, either. Absolutely if you put in a Tilton pedal box with dual masters it turns out beautiful. Even more so when coupled to a vacuum assist. Which I'll have a chance to drive on Friday in the form of a newly built Mat Lowrance state-of-the-art car ('86 930 chassis for PRC GTL) that will be out on its maiden test day.

Hi

In my experience the steel braided lines are inferior to the standard hoses. A new set of steel braided hoses are preferable to 15 year old standard hoses though. Just do not expect them to last 15 years.

I see engine oil, transmission oil and Brake fluid as Insurance, and cheap insurance at that. The delta between SRF, Endless etc. (~70/pint) and ATE (~15/pint) is considerable. However the DELTA between stopping at the end of a main straight vs NOT stopping is much much higher...

It's time for me to do a brake job on my 1995 cab. New brake hoses are in the mix for certain. My cab is an early build and I've read here about other 95 owners having trouble with getting the right hoses for early build calipers. Can someone advise how to determine what the proper hose is for an early build 95? Many thanks in advance!

mike993c2s

Yes indeed.....

Isn't it, to paraphrase Clapton, in the "way that you use them"? Three years of racing the RSA using ATE, at/near lap records, and zero brake issues. Even in Reno (testing only) at altitude. (Other than Laguna eating half a set of front pads per race weekend.)

Been using ATE in the faux RS for my whole ownership; have to remind myself to bleed the brakes a couple of times a year.
