| on mountain bikes we usually bleed backwards, attach a syringe filled with fluid via a plastic pipe to bleed nipple, open it and push fluid back to master cylinder. close just before you stop pushing syringe. on an mtb system its real small volume so even a small air bubble is noticed so pushing from low point of calliper lets air travel upwards . you'll need to make something to catch fluid as it exits at the resevoir, we had custom cap covers done with a hole and pipe attached to drain to a bottle. |
