Thanks guys. Went through the old receipts and previously there were some discs purchased at GSF, part number: NBD713. It cross references with Ferodo DDF954 - which seems to be 314mm disc brake.
Ok, so it seems I have Lucas system, as I dont have PR:1ZL code on the sticker and as per ainarssems LUCAS was mounted on PF cars therefore I would need Brembo pads P 85 038 for the front and P 85 013 for the rear. I think...?
Although on the Brembo site they have brake pads for LUCAS and BREMBO systems for 314mm discs...
