If your pads are sweeping outside the edge of the disc then the calipers are either not spaced out right or they are not designed to run a size disc that you use.
The last depends on your specific CP5040 caliper type:
- CP5040-12S4 / 13S4 is listed for 280,00 - 295,00 mm discs and would be OK on the normal discs
- CP5040-4S4 / 5S4 needs 315,00 - 330,00 mm discs to work
- CP5040-32S4 / 33S4 needs 330,00 - 360,00 mm discs.
(further sub-types are for trailing or leading caliper mounting, so ahead or behind the wheel center, the above are just examples!)
The casting of the caliper body is different on these so for instance an 4S4 on a standard 288mm disc would always tend to run outsde the edge of the disc with the brake pads. Can't help/solve that with spacing..
