Visit another Toyota dealer and get a 2nd opinion! When you go in don't tell them about your brake issue, just have them test the car to check if everything is normal and you go from there.

 

just have them test the car to check if everything is normal and you go from there.

I am afraid that if I will not point into the problem they will not be able to even detect it. Again, it is happening on very low speed.
BTW, any idea what it could be? Someone told me that it could be brake assistance line problem...

 

Update.
I visited dealership 4 times. 3 times they tried to fix it. Relapsed pads, rotors, adjustments, lubrication... nothing helped. On 4-rd time they suggested to take a test drive on another new RAV4 2016. So I did and found that another car is making the same grinding noise and knocks from the bottom. (btw, the tested car had the same odometer values as mine). So dealership decided to stop trying and opened case with Toyota Canada. Later on my friend, who got RAV4 2016 from his work told me that his car also making weird noise and knocks, but he doesn't care because it is not his car. Two weeks later I contacted Toyota Canada, and they said that technician said that this noise is NORMAL!!! and they will continue with my case only if they will receive more complains. So, I gave up.
If someone thinking about buying new RAV4 2016, beware, it has manufacturing defect, at least Canadian version. Think twice!!

 

I believe I am having the same issue as you. When braking slowly and coming to a stop it sounds like someone is hacking very quietly in the background. When I park on an slight incline and get of the car, the rear makes a squeak sound. I have approximately 4800 miles

 

No braking noise here. Knock on wood.

 

Finally I figured out what is this noise is. This is a gas waves hitting on the gas tank. And this is very easy to prove, the noise completely disappeared when gas goes below 1/3 of the tank, and very loudly on full tank. Going to talk with dealership about replacement...

 

Please let me know how this goes/went. I just bought a "new to me" 2013 and the noise freaked me out. I could tell upon further inspection it was the tank, but how odd is that? What would be replaced? Thanks!

 

I'm guessing your Rav was either built on a Monday when no body wanted to return to work or on a Friday when everyone was in a hurry to leave.
