Should I change my brake fluid?

[lh59]

Hi all, I am thinking of changing my Yaris brake fluid. The last time it has been change is 3 years ago by the local mechanic. It has already done 70k since. I am a very conservative driver and hardly use the brake since most of my journey is on the highway. The fluid in the reservoir is still at the maximum level and the color look really clean. Do you still think that I should change the fluid?

It is not a bad idea to change it once in a while. The alcohol based brake fluid absorbs moisture and that water ends up corroding the steel parts, which are the calipers. On my vehicles I typically do a full change of the brake fluid every 2 to 3 years.

I did mine after three year, it's not hard. Get a helper to pump the brake pedal for ya...

I did mine after 4 years, and the fluid that came out was almost just mud for the first few pumps, and the difference in color was extreme once I got the new fluid running.

I did it again after 1 year, and the fluid wasn't nearly as dirty--but some dis-colorization was present.

I have not changed my brake fluid since I purchased my used 07 Sedan.
Around 85K.
How much brake fluid is required for the fluid change?
Recommended fluid off the shelf or from Toyota?
What tools are required?
