Why does my car’s RPM go up when braking?

I recently got a new car and I noticed that sometimes when I brake, the RPM goes up. I don’t know if this is normal or if there’s something wrong, but I’ve never seen a car do that before. Why does my car’s RPM go up when braking?

If your RPM goes up when you are slowing down or braking, don’t worry, this is totally normal. When you brake, your car is slowing down to a stop. Your car’s automatic transmission is trying to adjust for the change in speed and this adjustment can cause your RPM to go up.
Now if you notice that your RPM is unusually high, you may want to check in with your mechanic to find out why your engine is working so hard.
