I'm sure those could be made to work if they are of an acceptable Ohms
range, but how do you mount them?
They are just elements.
Most braking resistors on larger machines are in cages on the top or
side of the control panels.
For small drives, they are oftentimes just screwed to the panel
backplane, But then they don't get that hot.
By the time you fab the cage, you can almost buy one new with a cage and
that is rated.

Looks like the cheapest one is about $30.
I've used stovetop elements from eBay for about $12 or so. If they
are good enough for
Haas in mass manufacture, they ought to be good enough for me.
