Too easy. I better get around to doing this. I occasionally get a rubbing sound under light braking and the pedal always feels a tad firm like it's biting a little bit the whole time. I'll definitely replace all the fluid. It's too cheap not to and it gets rid of all the crap that's got in there.

As an update for mine.
Almost 2 years and still working as intended. One of the best things I've done on the Hyo, besides HIDs  ;D

I did mine the other night. I ended up stripping it all apart just to be nosey. It was cleaner than I expected. No sign of moisture at all. I had a look to see if changing the original spring was an option. Being tapered it wouldn't be worth the hassle. Drop in the pill and bleed the line. I have a stiffer longer spring I could drop in, but it sounds like the C612 is all it needs. The thought of the rear wheel locking up sounds rather scary, so I'm happy I've done this now.

Yeah mine locked on but not hard enough to lock the wheel, could smell something riding along, then got home and couldn't 'walk' the bike. Smell was strong and the disc discoloured and hot as shit!
Mine's an '08 and had about 10,000km at the time

Do you guys have a hardware retail chain that does enormous warehouse sized hardware stores? In Australia the franchise is called Bunnings. Their stores are massive. That sort of thing is what you're looking for. A hardware store. Over here, it's next to the nuts, bolts and screws section.

I got mine from ebay, it was about 3 quid for a packet of three.  If you can't find it on there, pm me - I still have 2 left and don't expect I will need them so I can post you one.

I've noticed from some of the posts symptoms of wheel lock but why do we actually need to do this spring mod? What causes the problem?
