Its too cold/no time right now to change the brake fluid.... however if i just suck out the fluid in the resiviour and fill it up with fresh fluid is this going to benifit the system at all until i can make the bleed and put in fresh fluid in a month or so?

I see no reason why not as long as you follow though on the bleeding later.
I would consider the new fluid you add today to be old fluid when you bleed and replace it with new when the time comes.

when you bleed it just open the bleeder screws one at a time and let gravity drain it out. it you go crazy pumping the pedal, you are likely to damage the master buy sending the primary piston into a bunch of grit thats built up over the years. the normal stroke is a fraction of an inch when you hit the pedal.

thanks for the input.. yea the new fluid I add is for sure trash after it touches the old stuff

After how many miles should one change their brake fluid. And is it really necessary?

Brake fluid is a water magnet (hygroscopic). If you want to avoid problems due to rust and contamination change and flush your fluid every couple years.

Im ashamed to admit that I just changed mine for the first time this summer.
It came out looking like old engine oil. I flushed the old stuff out entirely, wiped the can out and refilled with synethic. The peddle pressure difference was noticibly different.
If you havent dont it lately, I would do it .

ya'll using synthetic dot 3 or what? I think I have a few quarts of it in the garage. Guess i'll do the 1 ton cylinder upgrade while im at it.

Use the Dot classification your brakes call for. If you use a silicone based brake fluid, it does compress under pressure, whereas normal brake fluid does not. However, normal brake fluid is hygroscopic.

Old trick, put a piece of 2x4 under the pedal to keep the pedal from going alll the way to the floor when bleeding.
