Hi all. Been back since Friday. Checked each wheel and one of the rears wouldn't spin by hand. It was the dreaded build up between the caliper and the arm. I had already done the other side some months ago after i heard the wheel grinding against the caliper. For some reason there was no noticeable noise coming from this one. Just split it enough to get a blade between the two as the last one was a 'pig' after i got it off. All seams good now. Thanx to all for your help. Well done!
