Nick,
Thanks for the warning, but I haven't seen or felt anything alarming yet from the EBC's (been using them for a week now)
The 6000's series is a new type of brake pad and I guess they're using diffirrent type of material for their heavy duty brake pads, as this one is specifically design for the X-Trail and the Pathfinder.
I guess, I'll let you know in about 10-20,000km's time if I'm still happy with them
The reports on the net suggest they're good pads and in fact yours is the 1st negative view about them that I've read so far (no offence to you mate)
