Which pads please
 

4 pot Subaru Caliper's, getting squeaky/grinding noise when braking,

My97 Classic

Use the search function bro, there's plenty of choices, depending and suiting your particular style of driving

Thanks bro

Performance Friction are my personal choice or Pagid 4-2

I like Ferrodo DS2000, never used PF but they get good press on here.

Speak to Ian @ Godspeed brakes or Alyn @ AS Performance.
