Stainless Steel Brake Lines?????

I am going to be replacing the rubber brake lines on my 83 300d in the next few weeks, and I was wondering if anyone knows where I might be able to find some stainless steel replacements? I have read posts in the past concerning stainless steel brake lines, but I havent been able to locate them using the search function. Any input would be greatly appreciated! Thanks.

Generally, any hydraulic shop can make them, and that way they will cost less than the stock rubber ones. Make sure they have the outer plastic cover and are DOT approved, though. Otherwise the fairly delicate stainless threads can get damaged and cause it to rupture.

I wasn't aware of any DOT-approved braided SS flexible brake hoses.

Thumbs up

DOT approved exist. Troutman (in Calif) offers them. Last I heard you can buy from them direct although many others distribute them (do a search).

X2 with whunter!!! The genuine article will do the job. If SS was required then it would be used from new.
The SS isnt the issue, the flexible rubber hose inside it is more important. I would be concerned that in time if the SS wire fails from fatigue cracking (common with SS) it could puncture the inner & so cause brake failure. I think thats why, unlike most hydraulic hose, brake lines are not reinforced with wire as there is too much vibration & flexing.

i put ss hoses on the front of my chevelle years ago. they eventually broke. ss can only flex so many times before it breaks. went back to stock rubber and those are still on there 20 years later. ss hard lines are good stuff, the braided hoses not so good for an every day driver.

Rubber lines flex and absorb the bumps in the road while braking. SS does not and you either get a pulsating pedal or wheel chirp under hard braking. Race cars use them for a reason. Street cars don't use them for a reason.
On a funnier note. Once upon a time I helped a friend install a motor in his car. He had SS lines as well. Trouble was the motor did not get grounded to the chassis (check your work). The only path to ground left was the SS lines! Toasty they got

I used stainless lines on my 84 F250 4x4, since it needed all the braking help it could get. Once I put those hoses on, I had no trouble with slowing those 35s, even towing a trailer.

I used SS lines once on an Audi. They initially improved feel, then blew out after about 5 years. These were quality lines by a reputable aftermarket manufacturer.

SS lines sound good in theory, in practice a quality rubber line will do the job just as well for a lower price.

I hear that the braided stainless lines chafe the rubber underneath and therefore must be replaced annually! They are intended for hard braking conditions (like racing) and not for daily driver cars.

Rubber lines are easier to determine condition. If the outsides look bad, the insides can't be much better. Then you know it's time to replace.

Same here... I put some Russell braided hoses on my "old beater" Chevy pickup years ago. They have been great and have had no issues. They also have much better feel through the pedal. They have been on there for 70,000 of the 182,000 miles. That chafing crap is a bunch of B.S. Especially if the hose is built and "INSTALLED" correctly. I was an aircraft mechanic for many years (A.P.). Every hose on most of the hydraulic systems I ever worked on were braided in one way or another. I think they will do OK on my car.

I got them from JEGS. They probably have a set that will work on the MB. I need to look into that.
