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/

No, at best the car will stall.
Using the emergency brake, shifting to a lower gear/neutral, or just letting off the gas would probably be safer. At lower speeds, the e-brake or downshifting for engine braking would be ideal.

At 120kph, I would let off the gas and look for environmental things to slow me down (incline, terrain, etc). If all else fails, downshifting and e-brake.
