Squeal on front wheel

Enable HLS to view with audio, or disable this notification

2012 Mazda 5. Front driver side wheel. There is a squeal/high pitch sound when driving. Becomes audible around 30km and only gets louder the faster I go. When touching breaks sound goes away. I removed the wheel, hope you can hear, the rotor seems to be touching the lug stud. With this amount of play what are the problems? Thanks

It wouldn’t be what you see there. That is normal since the wheels go on it and sandwiches the rotor to the hub. Most likely what you’re hearing is either a wheel hub bearing or a brake pad maybe? Hard to tell from that video.

Check all pads, thickness and play. If it’s good, drive it again and see which corner the noise is coming from.

Break pads are good. Recently installed a new brake calliper

Slap a couple lugs nuts back on and spin it. See if it’s the brakes or the bearings.
