Was all fired up to ride the FJ last week and then discovered no pressure on the clutch due to lack of clutch. Very strange that this has dropped without me notiicing it but now need to work out why. I've got some DOt3/4 brake fluid and recommended lcutch fluid is dot 3 or 4. is it the same stuff, ie. can I use the brake fluid for the clutch or is there anythign different?? Dave
