I'm going to order some HEL brake lines this afternoon, as advised by my cheif mechanic
Interesting point though about the calipers though Matt, although I doubt that what you say is occuring as the brakes where stripped and rebuilt last year. Might be work checking them again though while I change the lines and have access.
Thanks everyone for you're helpfull replies and consultancy on this matter
Hopefully changing the lines and having a clean out will solve the problem until I stick on a gsxr front end.
