My Dodge Ram did this and it drove me nuts so I took off the front wheels and pulled the brakes apart and the backing on the brake pad that rest against the piston fell out. So it would shift back and forth when going from forward to reverse and visa versa. I don't know what the inner brake pads look like on the Scat 392's but maybe it's the brake pad. Just a thought.It happens tonme when from reverse I go back forward and brake. Only few times though.
