You want to put that monstrosity on a tilting arbour saw, mounted
under the saw table and in the path of the saw-dust and have it work
reliably???
Not going to happen - guaranteed.

You want to put that goober under a car where it has to contend with dirt,
water, oil, ice, salt, road-kill entrails, and have it work reliably???

Common sense says it won't work and can't be made to work. Don't believe
your lyin' eyes.

It's the clearance issues around a tilting arbour more than the dirt
and sawdust. A purpose built caliper could be used on the opposite end
of the motor on a direct drive saw - but a drum would be just as
effective and smaller for the same stopping power. You don't need the
fade resistance of a disk brake for the application, nor the thermal
mass of a Lincoln car caliper.
