I wondered if it was the wrong size shoes fitted but the last time they were fitted it was done by a garage so just assumed they would ensure they were correct. 
The wheel bearings have all been replaced in the last 18 months and i only do approx 5000 miles a year in it... i just wanna try and get it sorted as i want to sell her on. 
Ill have to take the pads off and have a look. They are not that expensive to buy and ill fit them myself this time. 
Ill have a look at the back shoes as well to see. just wanted to see if anyone else had had a similar problem before i started spending the day trying to find the problem. 
Thanks
