hum on the right wheel

Hello friends.
my 307 sounds humming right on the way going; it is as if there is a friction while pressing the brake. I removed the wheel and looked. I couldn't see anything; but when the speed of 50 km exceeds, the hum begins; why could it be; I am currently driving the car. does it make a big problem?

The ball of the wheel that had sounded had to change, I had a problem with the company vehicle, the service had changed the ball. go to the service there is a short job ..

pads are making noise how many km have you last changed?

their pads are 5000 km; I looked tightly and it wasn't a problem; it can be on the ball, now it's always a holiday; garages are closed; I go slowly until the holiday is over; thanks for informing again

that sound comes from the bearings

I do not think that the sound of my brother from the bearing may have a lot to do with the brake

it comes from the belly ball, you have to change it.

I definitely have the same problem with the bearings, the bearing is drilled and the oil inside is running out, so it makes sound, you do not hear it after a certain speed.
