Brake fluid is supposed to be changed every 2 years on any car, but it's probably one of the most ignored maintenance items. The reason is that brake fluid absorbs moisture. This has 2 effects - it lowers the boiling point and it corrodes parts. It is a very easy job that is made much easier if you invest in a little pressure tank that threads onto the master cylinder that you pump up by hand and that pressurizes the whole system. The longest/hardest part of the job is jacking up each corner in turn and removing the wheel.
