Hi,
I just watched Dale Stone's video on the MT520s where he briefly talked about a "uniquely" shimano problem which he dubbed "storage contamination".
That immediately rang some bells (or brake squeals), as I over the course of two weeks made two of my bikes (both MTBs) season ready. Both were stored indoors, in my heated bedroom (standing, not hanging). Yadadada both of the rear brakes (XTs) somehow contaminated themselves standing still, all I ever did in those four months was staring at them. Lustfully.
Is there anything I can do to avoid that from happening in the future?

I had a similar issues with my bike. And I think it’s going to be difficult to track down the source of the contamination.
So my idea is to remove the brake pads and store them in an airtight container. And when the time comes, I’ll wipe down the rotors and calipers with brake cleaner and reinstall the pads.
What a relieve to read that. I thought, I was the only one who has that problem. <3
I was told by an experienced shop manager that the piston seals dry out and allow fluid to pass through to the pads after not being used for too long. He always made it a point to actuate the brakes every couple of weeks through the winter. I’ve started to do this as well and it seems to keep everything right.
