Annoying brake issue....
Discussion
Brake guru's I'd appreciate your take on this as it's beginning to drive me nuts...
When applying the brakes to come to a gentle stop, all is fine until I'm scrubbing off the last 0.5mph at which point the pads seem to 'grab' the discs and I get a deep sounding creak/groan coming from the brakes.
I initially thought this was because my discs/pads were very worn so I set about replacing them.
- I bought OEM discs and Mintex pads (incase the OEM pads were known for it)
- I completely cleaned out the calipers, wire brushing everything and washed them out with STP brake cleaner.
- I used copper grease on the back of the new pads, on the back of the shims, around the pistons.
- I used red grease on the sliding pins
Put it all back together, and it still friggin makes the exact same noise!!!
The only time it seems to ease up/go away is after a fair amount of braking when I assume that they have got quite toasty.

Sorry, thought it was an annoying Brake issue. 
S'pose that all you can do is approach the Stop line at a (slightly) higher speed and apply the brakes sharply. Or just put up with it - at least you know the anchors are in good condition for when they are really needed
Yeah It's just annoying that on a car that is designed for the ultimate silence, I have to put up with the brakes creaking S'pose that all you can do is approach the Stop line at a (slightly) higher speed and apply the brakes sharply.

The only thing that I've just found out it could be is that the pads/discs need conditioning as they are new. Granted it did it on the old ones too, but maybe its worth a shot.
Now I need to find somewhere to slow from 60mph down to 10mph at least 10 times in succession.

What does this mean? You bought OEM discs and non OEM pads?
If so, that's almost certainly where your problem lies.
It wasn't so much through choice. I bought non-OEM pads AND discs, but it turned out that my car has some 'sports pack' with bigger discs so I ended up buying OEM discs and keeping the Mintex pads.If so, that's almost certainly where your problem lies.
I've never heard of it being an issue tho?

Op, a mate had this on his Mazda 6. Nothing I tried would stop it. It almost seemed like vibration happened at a particular frequency at low speed which resonated through the rear suspension. It was very odd. Mazda were unable to improve it either.

Sounds like you've done a pretty cracking job pulling it all to bits - the only thing I would suggest is swapping the caliper retaining bolts around and making sure they're torqued up correctly etc. How does the rest of the suspension look?
I'll give that a try, thanks for the suggestion.Rest of suspension looked pretty much mint really and its had new air shocks in the past 5k miles too. I even went so far as to waxoyl'ing everything under there while it was looking so good.
Fair enough, but although all brake pads look more or less the same and do more or less the same job even tny variations in formulation of the pad material can give a greter tendency to grab, squeal, judder or whatever.
These effects rarely threaten safety in any serious way (unless you buy cardboard brake pads from India or Malaysia on ebay) but can be gently annoying.
Car manufacturers and their brake suppliers put a lot of effort into delivering a brake system which is tailored to the particular car.
