That's what I was wondering about. I thought I did see something about doing that every three years if you have not reached the mileage point. Something about it just being that old is not that good. I was not sure.

 

That's difficult to call. Yes, brake fluid is hydroscopic and absorbs water from the atmosphere, which lowers the boiling point (BP). However, it is a completely sealed system and about the only place you can absorb water is via the piston seals at each caliper. The master is sealed with a flexible "accordion" rubber diaphragm that theoretically keeps the atmosphere from getting to the headspace as the pads wear. With the minimal use you put on your vehicle, I'd be willing to bet you could easily go 5-7 years without issue. There are millions of cars on the road that are 10+ years old with over 100K miles that have NEVER had the brake fluid replaced. Now, if you plan to tow in the mountains where you can easily overheat your brakes, I'd say have it done.

 

Thank you, good read.

 

Its actually quite easy to call. The maintenance schedule calls for it, so you do it.

 

Definitely time to flush brake fluid. Get a pressure bleeder and flush away easy cheap insurance.
