Stainless Steel Lines for Brake Lines
Howdy,

What are you using for stainless steel brake lines. Also, does it matter if you're currently using 14" tires ? That is, if I upgrade down the road to 15" tires, will the lines matter ? Is there really a difference in the different types of braided SS lines I see out there ?

Please let me know, and thanks in advance ! Smile

RE: Stainless Steel Lines for Brake Lines
Braided SS lines, from a reputable source have been reported as the best upgrade per $$ for brakes...

For the hardlines I'd go cunifer. If you have a hydraulic bender maybe stainless hard lines, but it's probably tough to bend & flare.

No, the braided lines. Not messing with the current hard lines.

RE: Stainless Steel Lines for Brake Lines
Stainless braided lines do make a genuine difference, the cloth impregnated rubber hoses will inflate slightly when braking, this makes the brakes a little spongey, the stainless braiding prevents the hoses from being able to bulge out so more of the pressure from the master cylinder makes it to the calipers.

I got the Centric's for my 124 off amazon. Apparently Centric is a pretty reputable parts relabeler. Was the best deal around. I'd imagine they'd fit the 123 as well. Should probably figure out the lengths (meyle has a great online catalog that lists many dimensions of parts).

RE: Stainless Steel Lines for Brake Lines
im awaiting a set of goodridge braided stainless lines,
paied 155USD including shipping from UK, and hopefully they will turn out great,

change them at the same time a switch to gen2 w126 Calipers and new Brembo-discs, so its not like i can isolate the difference between brakelines... but im hoping for an awsome improvement.

anybody got experience of Goodridge or HEL brakelines?

RE: Stainless Steel Lines for Brake Lines
I think I am going to get flamed here but my experience is that braided lines are bling only. It's a braid and it will expand if the rubber underneath is soft. Think of a Chinese finger puzzle. Braided lines are the same. They will expand with pressure. Getting a good set of well made rubber lines are better than braided lines. IMHO the braid is on the outside for show.

RE: Stainless Steel Lines for Brake Lines
No. It's there to protect the teflon liner underneath and stop it from expanding (tie it together so to say). And there are more aspects... Rubber gets soft under heat influence - teflon/braided lines don't. There's less expansion especially under hard conditions (hot brakes & hot fluid). Rubber ages - braided lines have an almost infinite life. And last but not least, they'r less prone to damage by foreign objects.

They do have less expansions and there are some valid reasons to go for them. I've just had a set made for my car (about 100€) - and as soon as the bloody bleeders & hard lines have soaked some more days in penetrating oil they'll go on. They have a black rubber sleeve - and are far from any "bling".

That said - rubber brake hoses are much cheaper and for normal every-day driving they are more than adequate! If maintained well (i.e. replaced every now and then). In my case - my car needs to park in two areas with different martens - that's caused trouble in the past... So I'd rather have armored lines ;-) And then I also like to take my car for a very fast spin through the mountains...

Anyway; everyone needs to make they'r own excuses to fit expensive brakes lines. But there are good reasons that speak pro braided lines.

RE: Stainless Steel Lines for Brake Lines
I don't recommend replacing good rubber lines with stainless if you think you're looking for a performance increase.

When need custom hoses, I make my own using Speedflex. Good for 3000 psi and it's genuine teflon/stainless bling. I like to put heatshrink (red, if I can get it) over the socket nut and the first inch or so of the hose to make sure nobody ever makes the mistake of loosening the wrong nut when removing the lines.

RE: Stainless Steel Lines for Brake Lines
mainly durability "increase"
the 17" rims scraped against the brakelines on the peppy car, still works, but i dont want them to fail doing 250km/h ... so new lines it is.

also, im driving old w123s, nothing newer than 30years, and most of them have never had a brakeline change.... so i will change them Tongue

RE: Stainless Steel Lines for Brake Lines
My old rubber hoses are probably from 1987 so anything is probably better than what is there now.

Are stainless lines not preferred anymore for some reason? I have no experience with them but have always been told they hold up better and firm up the pedal feel since they're supposed to be stronger than rubber lines.

Braided SS covered extruded teflon hose is probably the best you can get. How much better it is than good modern rubber hose is up for debate. By '87 I think rubber brake hoses were good enough to be competitive with SS braid/teflon. If you've got original hoses from the '60's, replace or upgrade. The vast majority of brake system compliance comes from caliper flex. If you've got more hose swell than caliper flex, your case is exceptional.

I like braided SS because I'm into pretty plumbing and Speedflex allows me to roll my own if I've made a change that requires custom lines. Teh claims of making your brakes better are dubious though.

Here's a thread with some actual test results

RE: Stainless Steel Lines for Brake Lines
That's some interesting info. I'll probably still go with the lines from deerfield. I checked stock lines from ATE and it would be about $86 for all four so it's actually less for me to get the lines from the deerfield guys. The Speedflex hose sounds interesting and might end up being less expensive though. Do you know what size ends we need for our cars? The hose seemed fairly inexpensive but I didn't check out the fittings so that might make it equal to the deerfield lines.

The devil is in the details on the speedflex stuff. All the reasearch you've got to do to make a line can be a pita.

RE: Stainless Steel Lines for Brake Lines
Dumb question: are the lines already made and ready to install OR do you have to fab them in some manner ?

RE: Stainless Steel Lines for Brake Lines
The lines from deerfield are pre-made and ready to bolt on. The speedflex stuff is just hose and then you buy the fittings you need for your application.
