So got around to changing the hubs, discs and pads; went pretty smoothly although the handbrake mechanism needed some tlc to prevent binding. I went for some mintex discs and pads from ebay so I'll see how they fare. No new shims with the pads so had to clean up the old ones and re-use not ideal but the car needed to be back on the road for Monday's commute!
The calipers (front and rear) appear to be brembo but they look the same as the Lucas OE ones to me. Anyone know if they were an option?
New hubs made a huge difference at motorway speeds and fitting them myself allowed me to buy a new torque wrench
Picture of old near side looking pretty ropy! Forgot to take a picture of the new bits fitted...
