In their defence, they certainly did work! The NDX is an excellent pad - it worked far better than anything else i've used
There's a lot of info on the scoobynet thread (its a bit of a read) but the basics are:
- Excellent pad with no issues whatsoever in Brembos and larger calipers
- Excellent resistance to fading
It seems there are several people with heat problems on the 4 pot WRX calipers - they just cannot disperse the heat effectively. Not sure why this is - could be the caliper construction, the smaller disc sweep area... who knows.
The problem was that I'm used to a pad fading before it melts, but in the NDX's case (when I was at Brands) it resisted fade so much that the copper content started to melt before the driver experiences fade bad enough to want to stop. Apparently the copper melts at 1083c

It was this heat that caused the pad to crumble and 'smear'.
I said on the scoobynet thread that I was chuffed with their performance. It was only when I removed the pads I realised the extent of the damage to them. From brand new to ready for the bin in one evening!
