Why do I hear squealing o r grinding noises from my Mercedes E-Class brakes even though the brake pads were replaced recently?

My Mercedes E-Class W211 was serviced recently, and the brake pads were changed. However, I still hear squealing and occasional grinding noises when braking. Could this be due to low-quality brake pads, improper installation, o r other issues common in Pakistan? How should I address this?

Squealing o r grinding after brake pad replacement can result from:

Low-quality brake pads: Cheap pads often produce noise and wear faster.

Improper installation: Missing shims, anti-squeal grease, o r improper fitting can cause noise.

Brake dust o r debris: Dust buildup o r trapped stones can cause squealing.

Worn brake rotors: If rotors aren’t resurfaced o r replaced, worn pads can cause grinding sounds.

What to do:

Ensure brake pads are OEM o r high-quality aftermarket parts.

Ask the mechanic to properly fit pads with shims and anti-squeal compounds.

Clean brakes regularly to remove dust.

Inspect and resurface o r replace rotors if worn.
