Default Wheel vibration under braking - what is it?

Ok, so the wheel is vibrating under braking, discs?

However…. I can drive 0-50 and not have any issues under braking, soft, medium or hard.

However at 60 to 70 it is there and persistent even at part braking. Could it be suspension geometry?

I purchased car at 68,000 and was told ‘all new front brakes fitted’ however I can feel a lip on the disc which in reality is probably over 1mm quite easily! So maybe they are the original discs?

I have ordered a set (I am keeping the car anyway so will keep them in my garage if it’s something else).

It’s annoying as I fitted new front pads 5,000 miles ago. I have bought new pads but I got 55k from the last set and they still had lots of life. Is it a real no no to use 5k pads on new discs?

All I can assume is that they are the original discs where I assumed they were replaced on purchase. That said I got 55k from last set with quite a bit of life at replacement so it’s not inconceivable that at 68k when I purchased it the original pads were replaced and the discs have in fact done 120k???

Any thoughts?
