I am quite bored, so I thought I will write up how to change your brake fluid.
You probably need:
-Screwdriver
-Brake Fluid
-Spanner 8mm usually.
First of all. Locate your reservoir. Usually near your brake lever. For the rear usually it is above the pegs. You will see a canister that holds liquid.
Open it. There are 2 kinds. The bottle kind with a screw on cap or the other kind with a metal casing and 2 screws holding the top down.

After you open the top, there should be a rubber lining, remove that as well.
This is what you should see.

Go down to the caliper, you will see a small rubber covered nipple thingee. There should be a nut below and attached to it. Remove the rubber cover.
*either get a cloth or a rubber tube to attach to it. This is where the brake fluid is going to come out of.

Depress on the brake lever and open the valve, brake fluid should ooze out. Close the valve before letting the lever go.
REMEMBER: NEVER EVER LET THE RESERVOIR RUN DRY. KEEP TOPPING IT UP WITH BRAKE FLUID. You can't afford to have air in the brake lines.
Remember to start at the caliper that is FURTHEST from the reservoir.
Once satisfied that the old fluid has been flushed with the new one.
Close the valve and pump the brake lever until the pressure has built up. Hold the brake lever down hard and open the valve (do not let go of the brake lever, hold it down) the minute your lever is almost all the way in, close the valve. Pump the brake lever until pressure has built up again, then repeat the process a few more times.
At this point, the fluid should be oozing out with NO bubbles. If it isn't, keep repeating the process till the air bubbles are gone.
Move on to the next caliper, if you are working on the front.
Once done, fill up the reservoir to its "F" mark. Do not overfill as there should be space for air in there. There should be a little bubble in the gauge once you put the rubber lining and cap back on.
It is common for the metal cased reservoirs to have rusty or stripped screws. You can get the screws from a engineer. They are very hard to find as they are quite short and have counter-sunk heads.
It is best not to mix brake fluids. I usually use DOT4. If you want brake fluid that is BLUE in colour, MOBIL. THere is yellowish BP. A few other colours around as well.
HOpe this helps.
REMEMBER TO TIGHTEN THE NUT BEFORE RIDING AND PUMP UP THE PRESSURE IN THE BRAKE LINES.
Correct me if some of my processes are wrong. :D
