Thank you, that was my concern. Interestingly having taken a closer look and compared the two sides the one with the most significant contact is actual from the nut holding the bracket. Strangely one side has a nut the other doesn’t and on the other side the bolt doesn’t reach through to the calliper. I’m going to take a look at the weekend to try and work out what is actually causing the difference, whether it’s just the nut or the bracket itself and whether I have slightly different specs on either side.
