DOT 3 and DOT4 fluids are compatible and a little of one in the other is no big deal. They are both glycol based fluids. Even though this article goes into DOT5 (silicone based fluid) it pretty much says 3 & 4 are compatible. Personnaly, I would decide on which one to run, flush the system with it, and fill to the proper level.

You have to bleed you brakes. Fill it up, pump the brake several times and then hold it and crack the bleeder bolt(sorry i dont know what its called) open just enough to shoot fluid out. It might take a while but its the only way to get the air out of your brakes.

Close the bleeder bolt before you release the lever.

DO NOT let the master cylinder resevoir get low, it'll suck in air and you'll have to start all over again.

Good luck. :thumbsup:
