Brake line failures

[mach1]

So this year I know that Craig and Mason have both had brake line failures. I think Craig's was due to a broken zip tie that was keep the line off of something, Mason's happened right at the fitting. I was curious as to how long you guys are running stainless lines before replacing them, 5 years?

I was curious as to how long you guys are running stainless lines before replacing them, 5 years? I think I had about 4-5 seasons on the first set of fronts when I changed them. I am about there again and will go a little longer in length next time around. I should probably look closely at the line from the body to the diff as much as I'm off track.

I run factory fitment braided hoses on the rear axle, but I make my own 3an PTFE braided hoses for the fronts as my hardlines are all custom. Usually I take apart my fronts and re make them with fresh hose and olives after every season. About $10 in material...

I have replaced my rear axle to body hose once in 4 years, but haven't touched the axle to caliper hoses yet. My thought process being there is a lot less pressure, movement, and debris spray back there. I think I'll replace them after this season and retire the current ones as spares.

I don't worry as much about the stainless lines as I do the hard lines that were installed by the factory.

This.. the hard lines are what failed for me.

What? Any specific line? Was it rusted or fatigued or something?

The hard lines that are attached to the master cylinder failed from metal fatigue caused by the master cylinder moving up and down when the pedal is pressed. In my case, the actual flare broke off at the MC.

Ahh, mine has braided lines up there. I wonder about Jerry's lines now?

I decided to change my front braided stainless lines when I noticed a blue tinge (was using ATE Super Blue at the time) under the plastic coating. Never noticed a decrease in stopping power but changed them for peace of mind.

I forgot to take a picture last night, but on the 4th gens it is recommended to re-plumb and run the front hard line along the bottom of the radiator support. I have a ton of loops on the hard line coming off of the MC to relieve stress, but may take my front line section and turn part of it into 3an hose as that MC moves quite a bit...

All the stock hard lines on the 55 look like good with zero rust but I remember what happened to James and if I remember someone had a Fox race car blow a hole in a hard line (that looked great prior to the failure) somewhere between the M/C and the stainless flex lines on the rear.
