Hi all-

Apologies if this has been asked before, I've been trying to search but I'm getting the blank search result page

My question is, what is the effect of storing a mountain bike with disc brakes by hanging it up by either the front or rear wheel? I've heard that doing this will cause the fluid to settle in some way that's bad for the brakes, but I don't understand why. It's a closed system, right?

Any input would be great. My garage would be much more tidy if I could hang up the mtb's next to the road bikes!

What happens is if that the caliper becomes the highest point of the brake system what little bit of air is in the brakes master cylynder (brake lever which is alright if there is a small buble there because its not being comressed in the system) the air will travel into the line and posibly all the way to the caliper itself giving a feel of the brakes needing to be bleed but abit into a ride the bubble will go back into the brake lever where it is harmless again. One option atleast on Avid juicys but should work on others also is to use a rubber band or toe strap to squeez the lever which closes off the master cylinder and the air bubble from the rest of the system.

Great, thanks for the concise explanation, it's very helpful to understand what actually happens. I'm going to give the rubber band trick a shot. It's good to know it won't cause any permanent issues even if the air bubble gets down to the caliper.
