Decent Mechanical Disc

[OakLeaf]

I need to learn to bleed mine. I bought a set of Shimano dual control levers for practically nothing, and I can't install them without bleeding (to the best of my knowledge anyway).

Much easier with one of those vacuum gizmos. Failing that, much easier with a helper to pump the lever and top off the master cylinder, while you open and close the bleeder valve and hold the bleed hose to keep it from falling off the nipple. (I've only done m/c brakes, but hydraulics is hydraulics.)


And, define "ages." Brake fluid will absorb water from the atmosphere over time, so it does need to be changed periodically.
