Firming up the brake pedal - steel lines?
#16
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.

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,

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.

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....

By far the vast majority of racecar engineers will disagree w/ you on that. You are confusing effort w/ modulation.
ergonomically the human leg is far better able to modulate force at a fixed position vs over a moving range of positions, particularly so if you are operating the gas and brake w/ the same foot
w/ the 23.8mm m/c mention combioned w/ 930 brakes the effort goes way up but the pedal is rock hard and doesn't move a lot especially compared to a stock setup. This is mostly due to the slave/master ratios, the lower the harder the pedal
thru '76 911 41.3
boosted 911 thru '83 35.2
930 '78-89 33.1 early car w/ 930 brakes and 23.8mm m/c is the same just not boosted
964RS/Cup 32.8
993 37.3
993 tt 29.8
993RS 33.7
993 Gt2 evo 27.8
996Cup 30.1
997RSR 29.5

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.

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!

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.
