I recall that silicon (DOT 5) brake fluid can be let in for long periods. See this article for the reasons why. (Yes I know, this is not a MGB). Conventional vs Silicone Brake FluidHello - apologies if this has been posted a million times and will delete if another thread exists.
I have a 2013 T&C with 66k. Runs and drives great. Brake fluid is as black as your hat and is original factory fill. Was thinking about flushing it to the nipples, but I believe it's a lifetime fluid. Is it worth the bother? I have a Nissan Altima 2016 with 34k on it and I got it flushed at the dealer today as was recommended in Nissan service schedule. Any idea why Chrysler believe they can recommend not changing it in the vehicles?
