morepower Posted September 16, 2007 Share Posted September 16, 2007 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?

Gismo Posted September 17, 2007 Share Posted September 17, 2007 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 Link to comment Share on other sites More sharing options...
