rear brake issue

[iam]

Hi All.

Was looking at my rear brake discs recently and have noticed that on both sides only the upper part of the pad seems to have made contact with the disc.
Had it been on one side only i'd have thought of a seized piston but on both sides!?!
Any ideas why this might be?
Any tests which i can do?
Could there be any resultant problem due to me continuing to run the car like this.

Ps. It actually feels fine when braking although it could be argued that the pedal has a very slightly soft feel but that's debatable.

Thanks
Iam

That could be binding calipers or bad guide bushings. A rebuild of the calipers should fix it.
