How important are the floats in the brake master cylinder reservoirs? Actually, from what i've seen in diagrams, there are whole pieces of my m/c gone- the filters, etc under the caps. The remaining black rubber float looks like a burned up marshmallow. If I can just take it out and feel like I don't have anything to stress out about these parts not being there, i'd be stoked. Flushing it all out and bleeding tomorrow to see if we can get away with that rather than install a new m/c, but have a brand new one (sans soft parts and reservoirs) ready to go if necessary. The one on it doesn't look too bad but, of course, hard to tell by looking how well it's working. Oh yeah found paperwork in the car and the last time it was insured was 2006, so I'm assuming the thing sat up in Chiloquin in someone's yard for at least 3.5 years before it made its way to the junkyard.
