how do I properly change my brake fluid?
will bleeding them dry cause damage the master cylynder/calipers?

 

Here's what I do. I first suck out almost all of the old brake fluid from the plastic reservior, clean the inside of the reservior with a towel (or something that won't leave behind fuzz), and pour in new brake fluid. Then I bleed the brakes starting from the right rear, then left rear, right front, and finally left front. I always get a good solid pedal if I'm careful enough to not let air bubbles up inside the bleeder screws. It's definitely not a good thing to bleed the master cylinder dry since then you'll have to "bench bleed" it, which usually involves removing it from the car and all sorts of other stuff I've seen on TV and haven't had to do.

I've used the Ford HD brake fluid since its boiling point is 550 degrees and works great for road-racing. Speed bleeders make the job much easier, and you can even bleed them by yourself and not need a helper to push down on the brake pedal. Just keep an eye on the brake fluid level in the reservior and pump the brakes until clean fluid comes out of each corner...
