Noise when braking, even if at very low speed

[Prisoner627]

Hello everybody,
Does anybody have an idea of what could be this noise?

None of the 3 workshop (and one is Seat/Cupra) has a solution...everybody told me that it's "normal"...well, for me it's not...

Please, can anybody help me??

There are several things that could cause brake squeal. Has it had new brake pads? Has it been driven hard, so that the pads have overheated? Has it been driven so gently that the pads have "glazed"?

I don't think the brake pads are new (the car has been bought used), they could be the original ones. Anyway, they are in good conditions (so they told me at the ws, not seen by myself). Since the car has been in my possession, it has never been driven aggressively. I also have a young daughter, and in any case, I'm not the type of person who thinks he's on a racetrack every time he drives... I certainly don't have an overly kind guide, let's say somewhere in "between"

The noise appears occasionally, not always, it occurs when the engine is cold, especially in the morning.

What I would do is try to get the brakes hot, e.g. brake from a high speed with high pedal pressure, then carry on driving normally to get fresh air to the brakes so thy cool down evenly. There is a small chance that that might help. If not then I would take out the pads and if they are glazed/polished, sand the surface, and refit with some copper grease or something similar where the pistons push on the back of the pads. If none of that helps, I would be looking at different brake pads.

Ok, I'll try to do what you suggested @smiffypr
Thanks for now!

FYI
Problem Solved, rear brake pads replaced in a non official ws. As you suggested me @smiffypr, the front pads were glazed, and they have been polished and now they are as new

No more noise, thanks a lot!
And NEVER MORE SEAT WORKSHOP
