Many thanks all :-)
If it were me, I would:
1. Inspect the front calipers, there are slider plates in the caliper at either end of 'where the pad sits'. These become mishapen due to a build up of corrosion behind the plates. This wedges the pad and makes it more difficult for the pads to do their job. Also check out the caliper mounting lugs, I had one that was corroded through. The pistons in the front caliper do not
need a brake rewind tool - are they all working? Any corrosion on the pistons? How shiny are your discs and is it even wear on the disc? If not even & shiny then suspect caliper/piston problem.
You can buy caliper refurb kits but it can be a pain dismantling those slider pads.
2. The front calipers need to be bled properly, which means your bleed nipples have to be changed. Pretty sure I've used an Irwin extractor in the past. You need to see new fluid at the front & rears.
3. By the sounds of it you may have had the rear compensator brake lines sorted out. If not then look at mine here at Post 16. (Winter Refurb......getting there)
Reverse the car onto ramps and check out the compensator there by the rear sub frame.
4. Nothing wrong with getting decent pads, but you maybe masking the underlying faults in the system if you don't address the basics above and IMO snazzy discs are nice for show but I would be spending the money elsewhere for now.
