please read my post again mr colvert. ....
the o.p was asking about uneven pad wear. i was suggesting in my post that the pads whilst the vehicle was moving were actually springing out at an angle and could possibly be in contact with the discs at an angle thus wearing unevenly. this would also cause the pads to not sit squarely on the metal carrier guides. the pads wont move out of centre once they are up to the piston whilst being applied , thats true, but do we know that they are , and that they are fully square to the piston ? it would only take a very small amount out of square to effect them. ...
