Persistent judder/vibration under braking

[Blackstar]

Had steering wheel and cabin judder under braking for a couple of months.

 

I have changed the discs twice and the issue goes completely away for a week or so and then gradually comes back.

 

I have:

• Replaced discs and pads (short term fix then comes back as above).
• Had the bearings/hubs tested for runout.
• Replaced a wheel bearing which showed some runout (no effect).
• Replaced both lower control arms/wishbones (no effect).

 

Other things to note:

• All discs and pads have been Pagid. Maybe a bad production run/batch?
• Vibrates less the harder you press, but you have to press really hard to not feel it.
• It's mainly the steering wheel and cabin that vibrates, not the brake pedal.
• There is a slight squeak on right lock you can hear when parking.
• Car pulls to the left a little more than it has recently.

 

Any ideas/help would be much appreciated as not wanting to throw endless amounts at the car as it is now on 100k miles. Would be a shame to let it go but thinking about cutting losses.
