When I adjusted brakes on my 500, then washer/spacer for the wheel bearing against the drum fell out when I got drum off and I didn't realise. So when I put it back would spin freely until I tightened bolts up then it was solid.
Hi Mike this is exactly what I thought at first because it was happening on both sides but I have looked everywhere but I can’t see anything anywhere that’s dropped out but if there should be one in there that would explain everything
