Front noise problem

Good morning, i have a ford fiesta mk7 1.25 82hp 2009, I bought it in September 2025 used with 25,000 miles, it did very few miles a year, I proceeded to do the routine maintenance and replaced the braking system with Brembo Xtra discs and Brembo pads, after about 1,500/2,000 miles I noticed that it was making more and more noise in the front area, I took it to several mechanics but I never solved it, I hypothesized it was the pins of the caliper support, I greased them and it improved a bit but it comes back, I suspect that it is the pads (as if they were slightly smaller and moved, in fact if I brake the noise does not), as a second problem these pads whistle, I tried to clean everything and put copper grease but it does not change, will the pads need to be changed with another brand?

Thanks everyone for the replies

Many newer pads come with their "anti-Sueal" shims, but they don't always seem to be the correct fitment - causing a squeal due to their Hot-to-cool-to-hot cycles shift the pads on the rotors and even the linings of the drums if that applies to your vehicle here.

Did you happen to compare sizing of the OEM parts or Pads you did have, to the new ones before the install? Sometimes the previous pads clip-holders would work for another session or season to help with this noise.

You didn't mention if you resurfaced (Machined) the Rotors and Drums, so don't know if the sizing issue is the true fault here.Because the pads and the Rotors at the same time - you may find slack; as in being able to rotate the rotor or even have to use a lug-nut to keep the Rotor on, or worse - the press-on effect of age can affect the hub/knuckle to rotor heat transfer and generate hot-spotting that warps the mess sooner than later - forcing you to replace them due to that warp needs machining beyond tolerance.

The Best way would be to check for fitment and that precaution would have provided clues in what to do, return them, or grind off material on the brackets and hope like Hades they fit and you won't have to remove them for the rest of the vehicles service life. Sticking with similar brand or sizing is needed to maintain the OEM performance - does not mean you have to buy Ford all the time, but if you do this in the first place - this may have cured this problem without having to take everything apart and redo with new.

Hi, thanks for the reply.
I bought the car, but since it had been sitting in the garage for a while, I thought I'd replace both the discs and pads. I think the discs were original Ford ones, and the pads were Textar.
However, according to the specifications, both the originals and the Brembo ones are the same size. Comparing them to the old ones, they look the same to me. Maybe they really are the anti-Sueal ones. I could buy new ones and try, at least to eliminate this annoying noise.
If not, I could get a pad and shim kit, so maybe I can also get rid of the whistling problem when I brake.
