I just went into the garage to get the Little Truck out in preparation for the drive and this is what I spotted
A great big oil stain under the tyre with oil running down inside the wheel

So off with the wheel and brake drum and still not clear but the wheel cylinder seems OK and the brake fluid is not low.
So after cleaning the inside up it looks as if the bottom axle outer oil seal has failed - no idea was OK last week and no leaks. It is always the little things with these vehicles. The hub was down a little so I refilled it.
With everything cleaned I have placed a white piece of plastic under it and will see how much has leaked out tomorrow. If I remember correctly all I have to do to replace this oil seal is to remove the square plate at the back of the hub - remove the big nut on the inner end of the short axle and then pull it out from the other side then replace the oil seal and put it all back - that is the short version.
No matter what the season - there is always something to do on the Haflinger - and it was running so well .
