2010 Prius Deceleration When Foot Off Gas

First-time poster here. I have a 2010 Prius II with 150k miles on it. About a year ago I noticed a whining sound from my front wheel and suspected a bearing was going. I took it to an independent shop and they confirmed and replaced. Noise went away but this year I noticed it again. It got louder and sounded like it may be the other front wheel this time. Recently, I wrote it off as getting snows on and them being quieter while driving and thought I might be noticing more road noise. But today I drove to get gas and noticed the car was decelerating when I took my foot off the gas. Like really decelerating. It also felt like I was in B or had my parking brake on, but I didn’t. Best case this is another bearing that needs replacing. Worst case is this has something to do with the braking system. I’m terrified it may be a brake booster issue. I had my brake booster pump assembly replaced under warranty in 2013; this was part of the contaminated brake fluid recall. I had not thrown any codes then but the dealer inspected my vehicle and said I qualified for the replacement. I really hope this deceleration is unrelated, but I’m worried it could be. Are the two connected?
