Front brakes

[Justme03]

I have an 2003 gl 1800. Developed a brake fluid leak on the left front while riding when I got home pulled all the covers off to find it now it has no leaks that I can find while pumping up the brakes , had anyone had this issue

first welcome to the forum. second, could it be a front fork leaking? that could make it look like a brake line leaking.

Thanks M 2102 that's exactly what it is do you how much oil goes back in

[m2102]

Not sure exactly how much. Look at the tutorials and see if it has a how to there. Also it may be just needing to clean the bottom of the forks at the dust seal. They make a tool for it and some have made their own. Again can't remember what its called. Do YouTube search for cleaning dust covers on forks, simple to do. It's called seal something. Easier to do than a full rebuild on the forks. I'm sure someone will be along with what you are asking for.

Look on youtube for cleaning forks on a motorcycle, also found name of tool, seal mate is namw of the tool. Also shows how to make one. Simple ti and get back on road faster

I've used a feeler guage to clean the seals many times. Only once have I had to go to the special tool, so that can get you on the road quicker.

The amount of oil that gets out this way is minimal, so I wouldn't worry about toping up. Perhaps if you were racing it might make a difference, but not for us.

I would agree on checking the left fork and while you're at it make sure your Anti-Dive Valve (ADV) isn't locked up. It is common for the ADV to seize up when the brake fluid is not regularly flushed and once it locks up the ride gets rough it can cause the left fork seal to blow out.

Thanks for the help and advice. It's all fixed and back on the road!
