Nope. They are not a “cone”. A cup and cone system in a bicycle context is meant to allow bearings to roll around an axle in only one orientation. The spherical washers on the brakes is meant to allow for movement in different orientations. They allow for rim brakes to be toed to the rim, for example, or in this case allow for the caliper to the tipped if needed in different directions.
and the way the two closest to the frame are installed defeats their purpose, making them merely spacers.
For the most part, they
are just spacers. Spherical washers aren’t needed on disc brakes and many brands don’t use them anymore. But even in the configuration that azzzaoo6’s brakes are set up, the spherical part of either washer can rotate in any direction the same amount independent of the orientation.
that means it makes a difference.
No. It doesn’t. You
could replace them with spacers and the brake would set up much the same way that it does now.
i'm "going on" about helping someone get their brakes sorted out.
smh.
Not by bringing up red herrings.
