While I recognise the the brake system in my car is redundant, is it possible that failure to replace brake fluid could result in a fatal accident? or is there sufficient redundancy and warning systems in place that the operator of the vehicle would at least notice that there is a problem to have it addressed?
I ask as I just found out that my dealer, although required to replace brake fluid every two years regardless of mileage according to the service schedule, hadn't been doing it, ever (I have owned the vehicle for almost eight years now) so want to see if this is something that is simply a maintenance cost issue or a life safety issue.
My guess is it could result in corrosion of the components (as the corrosion inhibitors would be used up) and both hydraulic systems would likely corrode at a similar rate, potentially resulting in near-simultaneous failure, though that could take a while, and might be unlikely.
Are they putting lives at risk by failing to change brake fluid? Is it a big risk?
