Well if you had soft expanded rubber lines to begin with.. then yes you will feel a difference because the flexing of the line will be gone, and the hydraulic pressure will be sent directly to the caliper or cylinder.
^^^ both Dave and I use Goodridge brake lines. I've had them on for the past month or so and him for 3 years.
I am using EBC Greenstuff pads all around, and completely flushed the system and replaced with OEM DOT 3 brake fluid. I am VERY pleased with the braking improvements on the car. No mattter how many times I brake hard, each time the pedal feel is the same. In my mind the braking distance of the car has been shortened also... but there's no way to tell for sure without knowing what it was before.
^^^so true....bruddaman, I wouldn't look for brake lines in a scrap yard...u might as well find some old brake pads there while u at it and put them on ur ride one time
but the DOT rating on brake fluids have to do with the boiling point ("dry" as in "fresh out of the bottle" and "wet" as in "in use"..there's a percentage of water present "in use" but I cyah remember) as well as the chemical composition of the fluid
DOT 3 fluids are ether based and absorb water as if by magic (I sheit u not folks, by magic..u'd be surprised and scared shitless at the same time) which lowers the boiling point (sometimes by as much as 1/3 for a fluid boiling at ~400F contaminated with water that boils at ~200F)...not fun when yuh comin down Maracas hill!!!!!
let's just call it "water contamination magic" iite
when bled completely regularly (say annually maybe), u keep it performing just right
DOT4 fluids are ether based as well but treated to resist water absorption but once the "water comtamination magic" kicks in the boiling point drops off further and faster than DOT3 fluids do...so u hadda change it a bit more regularly
also the treatment doesn't bode well for seals and flex lines and fittings made for DOT3 fluid so don't use DOT4 if ur manufacturer says to use DOT3
DOT5 fluids are silicon based and resist "water contamination magic" so the boilig point is more stable..but it don't resist compression as well as DOT 3 or DOT4 fluids...thas pretty much all I know about DOT5 fluid
I got teflon braided brake lines
it cost $624.00 for the set of four at Hi Tech on wrightson rd (just after powergen if heading east) the fellas did it in about 1.5 hrs so it was pretty fast work
but u have to carry all four of your original brake lines so they can reuse the ends i think that is what fivefoward was talkin about carrying old scrapyard lines
