Brake fluid leaking

Post by Lovepug »

Hello everyone,
I hope I’m posting this in the right place.
This morning I came out to the garage and found a puddle of brake fluid on the floor by the center stand. From what I can see everything looks dry, but the rear reservoir is empty!!
I have a 2003 GL1800 with 93000 miles on it. Last winter I took it into the dealer for a complete look over adjust the valves that they said were good.
Any help would be greatly appreciate.

So put more fluid in it and see where it comes out.

Get a good flashlight and inspect the rear master cylinder for leaking. If the brake fluid hasn't been kept flushed yearly since new(2 years max) the master cylinder will likely be needing a rebuild kit, from gunk getting in the piston and cup causing the leak.

Sometimes if I can't find the source of a leak, I'll clean it up with brake cleaner to get rid of any leaked fluid, then dust the area with talcum powder (spray on aerosol deodorant works well). Once it starts to leak, it becomes very apparent exactly where it is coming from.
