997.2 Carrera 2, brakes squeal, but only in reverse.

As per title. They're absolutely fine in normal driving and spirited driving, but as soon as I gently apply them in reverse they set my teeth on edge.

Are they all like this? A simple fix? Just a grease of some sort on the back of the pads?

Thanks
