Speed sensor comf

Can i assume there's no way to test them?

With a multimeter, disconnect the WH senser, hook the meter to the two wires, should be a signal volt reading when the caliper is spun.
I think thats how it works.

Ring with teeth? Do you mean on the back of the rotor?

I was wrong on the ring with teeth. . I think The ring I remember was on the half axle on a 4 wheel drive.

I'm not sure how exactly the speed sensor works but I know the sensor does come with a new backing plate. it might be a good idea to replace it anyway. the sensor is only for the ABS not the trans. as for the grinder, I wouldn't grind anything but only use a wire wheel to clean off any built up rust. you can use a flap disc on the rotor only to smooth and flatten the build up where it ate into the pads and for the outer ridge on the rotor, just once that is done get you a new set of pads.

once you get it all back together and before you press on the pedal, you can test the slides by moving the caliper side to side by hand seeing if that is moving good.

And then before attempting to drive the truck, push the brake pedal as far down as it will go, about a half a dozen times.
