haha yeah i just had this problem two days ago in my 90 lx
first look for a little "nipple" type thing off of the slave cylinder right next to the radiator. then get a jar half full of dot 3 brake fluid. take a hose and hook it to the "nipple" and put the other end in the jar. open up the vavle by taking a wrench and turing it about 1/4 - 1/2 of a full turn. then pump your clutch untill you feel it is stiff again and there are no bubbles. repeat if necessary. once done close the "nipple" valve and put the dust cover back on
