Hi All, thank you for the help and advice, just to answer a few of the questions I bought the wheels from Swiftune although they had MiniSpares tape on the box just because MiniSpares didn't have any and yes they are def 7.5 cooper s brakes.
With some better light and and a bit of renewed vigour this afternoon I tried again and typically the wheel I had picked up originally had 4 weights and it was only these that were catching on the calliper, I thought the back of the bleed nipple was rubbing on the inside edge of the wheel but thankfully it wasn't. I fitted one of the other wheels that only had one small weight and this was just rubbing so with a bit of time and a file I have smoothed the calliper off so it doesn't catch the weight at all.
However, I'll take all the wheels back to the tyre place and get them to relocate the weights
Thanks once again for all you help
Darren
