I know, this is a Klaus brain teaser.......

In both cases it’s the LH caliper grabbing. Think about it - you’re rolling backward, apply the brakes, and the LH caliper grabs. That causes the LH wheel to thrust forward, which translates to the wheel arcing inward due to the steering geometry (so car turns right). Apply the brake while moving forward and the LH wheel thrusts aft which causes the opposite reaction.

But is it a case of the LH being too grabby or is the RH sticking in the bore and not wanting to apply pressure to the pads if the foot pressure is light. Jacking up the wheels and having an assistant apply light foot pressure while you spin each wheel should answer that question. How are the pads wearing?
