Car has 125,000 miles. Not sure if the brake fluid has ever been flushed, despite brake jobs in the past 5 years. I do not have the manual so not sure if it even addresses frequency of flushing the brake lines. None of the invoices mention it. Last checkup in Aprl recommends flushing brakes.
Lots of posts on Cartalk about flushing in general, but not anything for my Mazda 1996 Protege.
