non-slipping disk brake mounting

[jim beam]

thanks to carl fogel, here are some photos of my disk brake fork which i
hope offer a data point on slippage of a wheel axle when subject to
disk braking forces.

this image shows the inside of the fork end for the left side, the side
on which the brake caliper is mounted and therefore the side subject to
maximum ejection force. usage is removal and re-clamping an average of
twice a week over the course of just over 1 year. mileage is somewhere
over 2000. i weigh ~210lbs.

points to note:

1. clear bite marks from the axle facings which are stable and have
settled into a repetitive pattern of re-use.

2. no tearing or shear marks from slippage while clamped.

3. minor surface wear from repeated insertions. please also note that i
take care to jiggle the wheel around to ensure it's both seated
properly on insertion and to separate the disk pads on removal. this
will increase wear marginally.

this image shows the assembled wheel & fork. just in case anyone doubts
mileage and use, please note the thickness of the disk, or rather the
thinness of the disk. - contrast the width at the disk perforations vs.
the width at the disk spider arms. disk & fork are the same age.

Dear Jim,

It's fascinating that there have been no comments
on the only pictures concerning the disk brake
wheel ejection thread, given over 500 posts on
the original thread. Maybe everyone was out riding
and missed seeing them?
