some of the old fluid will remain. most will come out when you undo the lines and teh res cap. just flush a bit of the new fluid through the lines. when i changed lines i tried to get as much old fluid out of the calipers as possible. replace all hardware then go througn at least one res. of fluid through bleeding to try and get teh calipers cleared. fluids cheap and to me it was wortht the piece of mindFirst off, thanks!
So I do not have to remove all the old fluid first? I just release a bunch and add good stuff, repeat untill all the old fluid is out?
you can get one of the larger ones at the pharmacy, used for oral medicine.I find it helpful to use a big syringe to suck the reservoir just about dry first. Then I fill with new fluid and get on to bleeding. I honestly don't even remember where I got the syringe I use (no needle, of course). By the looks of it, I think it's used for horses... you could probably pick one up at a feed store / pet supply.
