Stainless braided brake lines throwing codes ???
I recently installed new rotors (from RM Racing) and Hawk pads on my 2001 Z06, and decided to also upgrade to stainless steel brake lines. Shortly after the install, I was driving when the DIC displayed "SERVICE TRACTION CONTROL", "SERVICE ACTIVE HANDLING" and "SERVICE ABS", then turned on the warning lights that show that ABS and AH/TC are disabled. When I shut down the car and restarted it, the lights cleared and the "problem" seemed to go away. Since then the same thing has happened several times. I have the car at the dealer today for other work, and asked them to check out the problem. They just called me and said that the problem is with SS braided brake lines. They claim they've seen this occur on other cars with these lines installed. Their "solution" is to either return to stock rubber lines, or accept the fact that the car will intermittently indicate a problem with the ABS/TC/AH systems. They believe the lines cause some kind of interference with the wheel sensors, and are supposed to be checking with GM technical services to see if they have more information on this. Anyone else had this problem, or been told that SS braided lines can cause this kind of problem?

Re: Stainless braided brake lines throwing codes ??? (BlackZ06)
I have seen this issue before on some other member’s vettes with the stainless steel lines. Most of the problems that have occurred have been usually on the track running under harsh conditions. I have SS lines on mine however, run it at the track, and have yet to see an issues with any codes popping up… They are telling you some factual information… I wonder if the brand of SS lines make a difference???? Good luck with the resolve.....

Re: Stainless braided brake lines throwing codes ??? (Smoke-N-Shot)
Two things I can think of, but the same issue. Mind you this is only a theory on my part. It may be a system compliance issue, i.e., the software has a function built into it to account for the system stiffness. If the lines present less overall system flexibility due to the limited "bulge" of the stainless lines when the brake sytem works, the system may be seeing this as a problem. Conversely, if the system has any air in it, there may be too much flexibility. Hard to believe they would program to this extent, but some of the work I have done on hydraulic systems has taken into account the flexibility of large actuators, but then again the system pressures are much higher.

Did you do SS brake lines all the way around the car?

Re: Stainless braided brake lines throwing codes ??? (BlackZ06)
I returned some Russell SS lines before installing them as I read of just this issue. In all the posts I read, all the users of Goodridge lines didn't have any problems, so I ordered a set of those and have yet to put them on. If you do a search of the archived "ss" topics, you should find the threads about this. Here's a link to the Goodridge lines I bought :

Re: Stainless braided brake lines throwing codes ??? (BlackZ06)
I think that my braided lines were made by goodrige? What ever they sell over at LAPD. I have not gotten any codes relating to the ABS or TC. Bu ti do have on about low coolant that is a MF to try to diagnose.
Good luck with the brake lines

Re: Stainless braided brake lines throwing codes ??? (BlackZ06)
I have recently started failing with C1226 RF Excessive Wheel Speed Variation (DIC displays same messages you are getting). What code are you getting?
The dealer has replaced the RF hub, connector, & harness, but I'm still failing with the same code.
I have had Russell SS lines installed for at least a year. If the theory of interference is true, why would it start now?

I saved this post on the Russell lines:

Although I think there is a slight chance these lines can cause problems (the Russell lines are not very good quality, and tend to bend at the crimps), I think you will ultimately find another cause for the problem.

Re: Stainless braided brake lines throwing codes ??? (BlackZ06)
Get rid of the Russells and get the Goodridge!! :eek: That will take care of it! I have been there, done that and bought the Concert T-shirt on this issue... I do speak from vast experience! ;)

Re: Stainless braided brake lines throwing codes ??? (vetterdstr)
Thanks everyone, I just placed an order for the Goodridge lines, and will install them as soon as I can find the time to get the car up on the jack stands ... Which hopefully will be this next weekend.

Re: Stainless braided brake lines throwing codes ??? (vetterdstr)
After a year and a half and 10,000 miles, I can't imagine why they would fail now, but had the front Russell SS lines replaced with stock today (rear on order).
Will see if that cures it.
Why would Goodridge lines be any different?

Re: Stainless braided brake lines throwing codes ??? (TooManyIDs)
I had the Russel SS lines for about a year when the C1225 codes poped up everytime I drove more than a mile. I changed to the Goodridge SS lines and the problem disapeared...I don't know the differences between the two products, but Goodridge SS lines will solve this problem.

The Goodridge lines appear to be higher quality. The Russells loose the ability to keep a good ground... that is what is causing the problem.

Re: Stainless braided brake lines throwing codes ??? (vetterdstr)
So, who has had the Goodridge lines installed for the longest period of time & miles?
Are the electrical gremlins that possess the Russell lines also going to possess the Goodridge lines in a year from now?
Since the stock lines are rubber, they are not conductive right? If you are saying that the SS lines are, I'm still confused on why the Goodridge lines would be OK?
Maybe I should perform a dissection on the Russell lines I removed?

The lines have to be grounded to the frame. the Stock lines are... the Goodridge lines are... the Russells are such POS that they dont ground correctly.

Re: Stainless braided brake lines throwing codes ??? (vetterdstr)
I had purchased a set of the Russells and when I went to install them, they started to leak. So I returned them & just kept the stock lines.
Recently, I bought the Earls but haven't had the chance to install them yet.
