I was bleeding the brakes the other day and ran into a problem with the rear fluid reservoir. The problem is I could not find an easy way to top it off. I tried using a funnel, but the "spout" was too large to fit.
My GF came up with an idea: Use a stiff plastic tube and a funnel. Check out the attached pics....
The tube is the perfect size to thread into the plug hole, it is stiff enough to hold the funnel upright, and transparent enough to show fluid level. Who says women aren't smart?
Y'All ride safe...
