Posted September 16, 200717 yr Hi all, I have a 91' jap fzr 400 exup. it's great apart from the front brake does not work correctly. if you pump the handle the brake starts to work but once it has been used the handle goes all floppy again. there are no leaks. any body have any ideas on how to fix it?
September 17, 200717 yr Must be air in the system, or, getting into the system. Can be that the pads are well worn initially, is there fluid in the cylinder?? The hoses may be bulging, maybe need replacing

The hoses may be bulging, maybe need replacing Hey Gismo! thanks for the reply! the pads are half worn the disc is 90%. the hose's air o.k and there is fluid in the cylinder. i think it could be air in the system. do you know how to bleed it? cheers
