I'm sure there are many posts but the search didn't quite bring up what I was looking for.

Today my 3 year old Guide RSC suddenly got squishy, then it was fine, then squishy again. It almost feels like there is something moving around in the piston that gets out of place.

What do I do to fix it? Don't say buy XTs (although I might depending on how annoying this is).

Air in the reservoir can get into and out of the lever cylinder causing intermittent squishiness. A full bleed is best, but a quick fix is to rotate the lever so that the bleed screw is pointing up, attach a bleed syringe with fluid in it and push gently and pull gently until bubbles stop coming out. That'll get rid of air in the reservoir. This is best done with a bleed block in place to ensure you don't over fill the brake.
