Nasty sound this

morning - passenger wheel, scraping noise and screeching like a banchee! Noise was with the wheel turning while moving … obviously… anyway - parked up and looked at the brakes (it sounded a bit like when I had a brake pad come loose in a drum - maybe a little less rattle) the front pad on the passenger side was worn right down at the front only, rear of the pad appeared new! Checked the other side - it was the same! Beautifully chamfered! I was wondering if there are two ‘pots’ and if they are on separate systems - and maybe only the front pots are pushing? Is that possible? I had the brake system - pads and disks replaced a year ago, so m thinking maybe there is some missing brake fluid - I’ll try and check.. I’m an Mc wrencher but don’t know cars so we’ll. any ideas - im thinking the noise could have been the disks and brake pads. Taking the car anyway for a service tomorrow at the same place that did the brakes last - could it have been that they didn’t fill the brake fluid… I think it takes less than a year to wear like this though - I guess it could have leaked at some point recently - need to look in the reservoir I guess… so have to look where that is..any thoughts welcome! 

I think you'll find that brand new pads look like this.

As above, the chamfer is completely normal...

 

Random new example pads:

Shame, then the horrible noise

is something else

Such noises are often caused by a small stone getting caught between the dust shield and the inner surface of the disc. Generally will fall out again once they've worn down a little.

 

Hopefully that’s it

Reversing can also sometimes dislodge a stuck stone (assuming it's that).

The dust shield behind the brakes can corrode off its mounting bolts and then contact the disc. Lots of noise but not serious. More likely to be a stone if your car is less than 7/8 years old.
