Squeeling Brake

Had several arguments with Renault over this as the cars only 2 months old burns they say it's a natural occurrence as its dust build up but I think it's **** as its only coming from the front left brake.

What are your guys thoughts as why is Squeeling? It seems to shut up if I've been driving for a while? Are they crap pads they use on these brembos or something?

Here's a video sorry it's not great quality

They do get a lot of brake dust on them you have to clean them regularly and put copper grease on them that stops it squealing
 
On a new car i'd be expecting renault to sort it out.

It's not something you should have to do yourself.
