Hi Gavin. Thanks for submitting your question today. In most cases, grinding while applying brakes is caused by worn brake pads (which you indicate were recently replaced), debris trapped between the pads and caliper, or using lower quality pads than OEM. Worn wheel bearings will also make this type of sound. Unfortunately, without completing an onsite inspection personally, it’s hard for us to give you a repair solution.
