Has the lid ever been removed before?
Did you remove the lid after you saw the leak to inspect the rubber seal? What the current oil level at in the sight glass? The reservoir isn't really under much or any pressure during normal operation so unless your reservoir is way to full then your not forcing the child out, it's just splashing around and seeping out. It looks like the rubber seal has fail because its cracked or maybe pinched because someone didn't put it back together right. If you don't see anything wrong when you take it apart then clean the rubber seal along with the edges of the reservoir then reset your oil to the proper level and put it back together and go for a ride. If it still leaks then go buy a new seal and repeat that last step with a new seal. Hope this helps. |

Did you add fluid recently?
If so it could be the diaphragm is seated incorrectly. I would remove the cover clean and inspect it then check the diaphragm for damage.

what do mean by lid? and the rubber seal? where is it? i really really have neither idea nor experience about brake, I and nobody else never opened it, serviced it. so the fluid just happened to accidentally leaked out ! when there was an oil, I just wiped it with cloth and the brake works just fine ! but I m worried about it where should i check first? what should be good position of steer to check the level of reservoir?

Remove the two Phillips screws on top and carefully pull off the lid, Under the lid there is a rubber gasket that seals the reservoir. Clean the aluminum lid with some brake cleaner and inspect the gasket for any tears. After cleaning the gasket make sure your reservoir is filled to the middle of the sight glass and reassemble. Go for a ride and see if it still leaks.

Agree with Jason.
Once you check the gasket, you'll see where the leak is coming from.

I just heard it now, will check in the nearest store tomorrow. what if I couldnt find one? can i just use water or something? i assume : lid = reservoir cap. and rubber gasket = diaphragm. are those correct ? thanks

BTW, when you wipe brake fluid, make sure you use a wet cloth then dry thoroughly. Any residue of brake fluid left on a painted surface will eventually make the paint peel. |

If so, there is nothing to worry about, unless the level is too low now. Check the fluid level through the glass window in the reservoir while the handlebar is in the neutral (center) position. Half height of that window is an OK level for the brake fluid inside. There is a neoprene diaphragm under that cover that isolates the brake fluid from the atmosphere. Those screws that hold the cover are very hard to remove, specially if you don't have a JIS (Japanese Industrial Standard) screwdriver. Yes, you can use just water and a rag to thoroughly clean the mess.

Maybe the previous owner overfilled the reservoir and now the pistons in the caliper got separated for some reason (steering rapid shake?), sending fluid back to the reservoir and over-flowing it.
If the front brake works OK and has a firm feel, there is no need to open the reservoir.

Yes you can use water and soap to clean the brake fuild but don't get any water or soap into the reservoir, you don't want water in your braking system. I use brake cleaner because to kills oils on contact and evaporates immediately so you can see if new leaks develop. Here a quick video of what to do don't mine the break in the middle, after all I still have work to get done
