when your brakes fail, can you shift to Reverse in order to stop the vehicle? why or why not?

Question

I’m mostly thinking about a scenario where you are going down a highway (say, at 120kmh for the sake of the example) and suddenly your brakes fail

could shifting to Reverse function as a brake in that situation?

edit: thank you all for the answers, I want to note that I myself don’t drive and did not consider doing this, I was just wondering if this was possible

have a lovely day o/

I did it once in. 1972 mercury. Brakes went while on the highway, I smashed the parking brake to prevent a crash, that didn’t take enough speed off so I slammed it in reverse and locked up the back wheels. It did stop. I didn’t hit anything. I’m sure the trans hated it, pretty sure I messed up the bearings of the drive shaft a bit too…

But, and old enough car, it is a viable (terrifying and last resort) option.
