New front discs and pads - screeching

[Chris22911]

Hi all,
Recently had some new pads and discs fitted to the front of my 2016 C200D, Non genuine but of a decent quality but have noticed a screeching sound Initially when using since fitted. Has been around 4 weeks since they were fitted now, seem very responsive but the screeching noise when I press the brake initially has never disappeared, any suggestions?
Thanks

What pads were fitted . I've had mintex before and they were horrendous for it. I always look for pads with a central groove. Helps with brake dust . I avoid full faced pads.

If you pop out the pads , you'll probably see signs of glazing , basically brake dust that's been cooked , and is now sitting on the pad face . Rock hard and super shiny. Or it's bits of copper in the pad , used by some manufacturers.

Had something similar on my C240.
I replaced the rears with Brembo's and they screeched like mad, but when I put the OEM Mercedes silver backing plates on the pads and used some ceramic brake grease the screech disappeared

Interesting, recently replaced my discs and pads all round, no issues, not much dust and work perfectly. They did come with a small sachet of grease but I think I just smeared copper grease on the ears and around the slide pins.

Things have moved on since then, Mintex are now owned by TMD Friction Group GmbH, and I quote
“one of the globes largest manufacturers of OE brake friction”

Only in the initial phase of brake application - Y/N? Quietens as more pedal pressure is applied - Y/N?
