After thinking about a brake fluid flush on the Jeep the other day, I poked through the service records, and realized that it likely still has the original brake fluid in it. IOW, almost 14 years old, and 14 years of untouched bleed screws. At that point, being that I'm planning to re-do most of the brake system with upgraded parts anyway in a year or so, I decided against taking the risk of breaking off the bleed screws in the calipers.
So, I figured I'd try the turkey baster change on the MC just for kicks. Yesterday, I drained the reservoir most of the way and then refilled, which left it with pretty clear fluid. I drove a bit more after that, and a good bit this morning. Today, I checked the reservoir, and the fluid was starting to look dark and gross again, so I changed it out. Pedal feels seems pretty much unchanged in normal driving, although it seems to be a bit better (firmer) under heavy braking.
I'm thinking that while obviously a full bleed is much better, the turkey baster change can definitely do something (being that brake fluid is hygroscopic, the new, dry fluid will draw some moisture up through the system and drop the total moisture content of the fluid in the system). Has anyone else tried this and had any good/bad results?
