SS Brake Line on Rear...not recommended?

I am looking to upgrade my brake lines this winter and I read somewhere that it is not recommended to run stainless steel lines on the rear brake due to something about pulsating from the rear under hard braking and the non braided lines allow expansion when this pulsing occurs. Putting SS lines in wont allow expansion and can lead to problems. I do not remember exactly what the problems were or what the pulsing was, but has anyone ever heard this before?

I never heard this before and by a mechanical standpoint makes no sense especially how much a rear brake is used on a bike. I have ss braided and have had no problems in 10+ years. But i can not give insite on that comment maybe someone else can if thats the case.

"Hi,
Since Al washers are uncommon where I live, I don't like Ti banjo bolts (they breaks easily while tightening cooper washers, if you got a matter to reassembly the lines/master cylinder).
Secondly I would not advice to use braided line for rear brake. I got one exploded under hard braking, because of high pressure pulsation, while rear wheel is jumping under the hard breaking. I like rear brake stock line capability to expand/absorb those pulses.
Just my 2cnt."

Re: SS Brake Line on Rear...not recommended?

Since they're so rare, I wonder what a standard crush washer goes for on the black market in Rhode Island?

Re: SS Brake Line on Rear...not recommended?

Sounds like complete poppycock to me I've had regular lines, Goodridge lines, HEL (currently) and Kevlar lines (specifically on the rear of my original 900). All without any operational issue whatsoever. I've designed my own lengths and custom set ups on a few different bikes. Granted I've never been on a track so I can't comment on that, but I've heard and read that the rear brakes are RARELY used if ever on the track. I would give the comments in that thread in regards to your concern no credit. Especially for street use.

Re: SS Brake Line on Rear...not recommended?

I've had both on my RC51, I could hardly tell the difference. Placebo?
I did end up adjusting the angle of my brake lever so that I have to extend my ankle a little beyond comfort in order to lock the rear tire so as to avoid that possibility. That way, I can easily cover the rear brake a tiny bit with out worrying too much about using to much brake. If that makes sense.
Had the steel line on for 3+ years now.

Re: SS Brake Line on Rear...not recommended?

I don't see how people break banjo bolts, they are only tightened to something like 14 ft lbs., and if aluminum banjo bolts don't break when properly tightened, I wonder how much force was used to break Ti banjo bolts...


Ian, here is another teaser, Spiegler line and Ti bolts

Re: SS Brake Line on Rear...not recommended?

Appreciate the replies. I figured that much, but just wanted to make sure before I ordered the rears.

Re: SS Brake Line on Rear...not recommended?

I don't understand why on earth one would want Ti banjo washers anyway.
The aluminum is soft and acts like a rubberwasher to seal between the fittings and the bolt.
Does Ti do that? I was under the impression the answer would be a resounding no.

I don't see where he is talking about Ti washers, but yeah, I would stick with aluminum or copper washers there.

Mikeo, this is where I got confused.
You're right - he didn't say anything about Ti washers afterall. My bad.

I think you'll find on Hondas it's more like 25 lb/ft
