Metal Brake Line Source Recommendations?

[mssl72]

Has anybody tried to treat/coat the OEM type lines to keep that "like new" appearance?? How often do you change out the brake fluid?

Thanks

I spray them with Boe-Shield and they last for quite some time with no deterioration.

In my case, once in 42+ years [img]<<GRAEMLIN_URL>>/shocked.gif[/img] .....although I don't know that I would <span style="font-style: italic"><span style="font-weight: bold">recommend</span></span> that to anyone. I had a 73 Z28 that I purchased new and kept until 2000, and that still had the original fluid in it when I sold it. Never had any brake problems with that car, either.

Seriously, this seems to be a subject on which no one has any universally-agreed-upon opinion. As best as I can determine, this is a fluid for which manufacturers of most vehicles have no recommendations for change intervals. If it was as important as many repair shops and technicians would like you to believe, I find it odd that the manufacturers have nothing to say, when they are very specific about motor oil, trans fluid, coolant, and many times differential fluid change intervals.

The lid has never been off the master cylinder on my 1970 Z28 since the car was built.
