I’m a bit confused about brakes which have a separate bleed point at the lever to the one at the reservoir/master cylinder,
I break all those rules of mechanical correctness I posted as well as cog/sprocket. I have two rubbish “toolzone” quality adustacle wrenches as well as a stilson for big/stubborn ones. 😳
FWIW the brake lever is the bendy bit your finger(s) move to make the brake work, which uses a cuple of pivits and other gubbins to pump the master cylinder. So in shermer’s correct world, his lever should be the simple mechanical bit of the assembly, the master cylinder or reservoir will be where he gets to pump in or drain out brake fluid.
A lever.
A master cylinder.
Of course if I referred to it as such hardly anyone would get it. When my formulas went in for warranty the excellent warranty guy and I both referred to the complete master cylinder assembly as the ‘lever’ and seemed to understand each other. I don’t think either of us got sprocket-rage about it. 😀
