w212 rear wheel brake squealing

[krotov71]

hi
my car with 11k on the clock, one side brakes squealing badly when slow braking
i sent the car to main dealer to sort the NOx sensors out and see the brakes, they said the brakes need to be replaced to get rid of noise, charge £211 for rear only. the pads are almost new, i took the calliper out and clean all, put the MB brake grease but its help for one day only...
new pads?
thanks

Its possible that caliper slide pins need a clean and lithium grease . pads could be glazing .so even new pads would do the same.

I was take the original pads away, clean it, put greese on and use file to rub them on ages. Noise free for half a day and then again, piss me off a lot so bought ATA new set and no squick for 3 days already, let see... Thanks for response
