Default Front brake line replacement

Should rubber brake lines to calipers be replaced at some point due to age?

From what I read yes.

OEM seems the way to go based on my research although some opt for SS lines.

Yes. Nothing lasts forever...OEM rubber lines last the longest, but most opt for the coated steel braided lines for a stiffer pedal and brake feel.

To some degree this firmness is just due to a new line. I'd go with rubber. I have SS on the track car and those have to be replaced as well due to age and use.

My car is 18 years old with low miles, fluid changed yearly regardless of mileage.
Put in pss10 suspension so I thought I might change brake lines too.

Very easy to do. Just make sure you have "line wrenches" and go thru the DIY's on here or elsewhere, for tips. I didn't have any of the horrors that others experienced. They all cracked free pretty easily. Again, good wrenches and square leverage will do it.

Between about $75 to $120. This will depend on relationship with dealer and/or parts manager, and whether you are a retail or whosale customer.

I pretty much only buy Porsche and Mercedes parts from dealers one of which I have dealt with over 33 years.

Some dealers charge a lot over MSRP.

Or just buy from sunset that usually charges under MSRP and sometimes significantly under and ships to your house. And no sales tax either.

Sunset is excellent and sometimes hard to beat. I do try to buy locally if It's reasonable.

Agreed...But as I originally stated, nothing last forever; so why the steel braided lines on your track car, if all else is equal?
What is/are the advantages of steel braided lines?
...Other than rubber lines over time are subject to swelling, stretching, which resluts in a decrease in braking performance.
