Re: Complete Brake Fluid Change

I'm a little late here, but what I do is open the master yearly and suck out the fluid, and replace. That changes most of it. Every *Few* years, I repeat that, and additionally open the lines at the brakes, and refill.

It's incorrect to open the lines and drag all the fluid (presumably with all the accumulated gunk) thru the lines and out the wheels, for obvious reasons. The right way to change fluid is to suck as much as you can from the the top of the master, and then open and drain the lines to remove what's in them.

Brake fluid should be replace every two-three years, (or when it turns deep yellow from the original light yellow)... there's a hole in the top of the master to allow the air to escape which results from applying the brakes and moving the fluid. However, this hole, however tiny, also allow moisture in, and brake fluid being hydrophilic, it quickly absorbs it, and over time, erodes the fluid (and your master cylinder), so regardless of OEM rec's, it should be monitored and changed.
