HouseCallAuto 7/13/2010You have to bleed out the air from the slave cylinder. The clutch master is where the fluid is added.. There is a special and specific bleeding procedure that has to be done exactly as stated in the shop manual. You really need to have a shop manual to perform this procedure. There are special tools required as well.
