Was just wondering if there is any real benefits to having stainless steel brakelines installed on the S5?
Thanks Ian, was talking about something like this: http://www.brakes4u.co.uk/goodridge-car.asp but the S5 has something like this already?None.
...If you're talking about the flexible hoses... I'm informed by APS that the S5 has braided lines already, but they have a plastic protective sheath, so they look like plain old HT Plastic.
...as for the fixed pipework... definately none!
Your welcome... I asked APS if they could find some for me and they told me that they were steel braided already with a plastic/rubber coating... so no benefitfrom the linked Goodrich lines...
...You probably already know this, but for those that don't; the benefit, is from the fact that rubber/plastic lines become 'soft' at very higher automotive temperatures (such as when on a track day) and this 'softens' the brake pedal as some travel is taken up making the lines expand instead of pushing brake fluid through them... when really bad, your foot hits the axminster and you're still not stopping... which I did several time in my dad's old MG, before I learned to drive properly! ... and it is somewhat alarming.
Steel braded lines do not expand this way, retaining the brake feel... If you can't stop then, then you have exceeded the temperature of the friction material and you need better cooling or higher temp materials... or to slow down and use the gears more!
Ian could this be another difference between the UK/US spec cars or could APS have got it wrong?I just checked my factory brake lines since they were replaced with S/S brake lines previously when I went with a BBK. The factory lines are definitely 100% standard OEM rubber lines. Very flexible and not stainless steel braided. I did notice more positive feel once they were changed out. My pedal is very linear compared to the factory setup but it is questionable regarding improved stopping distance since the factory setup is excellent already. Probably much less fade and more consistency though.
Just a quick note to keep in mind, DOT 5 can only be used in brake systems it's designed for, it's not a simple matter of changing it over. However DOT 5.1 can be used in normal brake systems.Brake fluid upgrade always helps as well, something like dot five will give an improvement for tracking and fast road, less air bubbles form in the fluid at high temperatures, thus performance doesnt deteriorate as fast
'Ian could this be another difference between the UK/US spec cars or could APS have got it wrong?
Correct yes, with better fluid as well they certainly will be better.I take it then that the stainless steel brakelines are worth getting then....
