You might want to try posting in the "Prerunner" or early model Tacoma folders. This one is for the "pre Tacoma" compact trucks and 4Runners and therefore doesn't have the traffic the Tacoma folders do.
I installed a set of Wheeler's stainless steel brake lines about a week ago.
First, I bled the system (including the LSP&BV) to replace the fluid. The fluid flush needed to be done anyway (30k interval), and I wanted to see if there was any noticable difference with stainless lines. I drove on the old lines and new fluid for about a week.
Then, I changed the lines and bled the system again (all five points).
At least for me, with the stock rotors and NAPA ceramic pads, there is a huge difference in pedal feel. There is about a half inch of play before the booster kicks in, but from that point the pedal is very firm and braking very positive. I have had to learn how to stop without that final lurch again.
I suppose the age (5 years, 110k miles) of the original lines must be considered in the comparison. I'm not certain how SS lines would compare to factory new stock lines, but i wanted to throw my :2cents: in.
BTW, Wheeler's was very good on shipping cost and time. I think next I will get a new set of rotors (and probably pads to go with) from them.
I think you will find that most stainless steel lines are only cosmetic. They put the SS sheath over a traditional hose that contains aramid or some other braiding material. True SS steal lines can fatigue and cause failure. That is why you see a lot of these lines that are not DOT approved.
