If you can change brakes then this is easy to do. You basically just undo the two lines to the master cylinder, undo the two bolts holding it on, disconnect the 2 electrical line thingys, then remove it. unscrew the two screws holding the resevoir on, put the old resevoir on the new master cylinder, put new fluid in without the filter in, bench bleed it (push on the metal rod thing while it's in a vice and keep doing it till there are no more air bubbles), then put the filter and cap back on, reattach to car, bleed the breaks to get all the fluid through. When bleeding on the legend you do the passenger rear, then drivers front, then driver rear, then passenger front. To bleed the brakes you just take off the wheel, have a friend press 3 times on the brakes and hold, then you turn the bleeder nut and fluid comes out, then you tighten the nut again, and your friend releases the brake pedal, then you do it again and again and again. I recommend attaching a rubber hose to the end of the bleeder thing while doing this and draining into a bucket. Keep in mind that brake fluid is very harmful to paint, so have some brake cleaner handy.
