thanks for the advice
I tried your suggestions yesterday resulting in even brake temperatures. Looks like I just needed to concentrate a bit more in the landing roll.
1) Less eager to get on the brakes early.
2) Definately no nose wheel input above 60kts
3) Consiously using even brake pressure (checked by Capt on the guages)
That confirms it was my problem and not the aircraft. I was a bit suspicious of the spoilers on this aircraft because it had an intermittent fault occassionally preventing green spoiler deployment.
Thanks
