Yes.
I had a similar problem with my MK3.
The solution to the problem was to minimize the gaps between the rear brake drums and the pads.

In the front brake mechanisms, the gaps between the pads and discs are determined only by the elastic deformation of the rubber sealing rings of the front brake cylinders and, by definition, can not be large.

In the rear drum brakes, the gap between the pads and drums is determined by the compression springs and various additional mechanisms to minimize the gap.
At the Transit MK3 ... MK5 this additional mechanism is often defective.
Therefore, in the absence of air in the system, the brake pedal has a large free stroke.
fuzzedup,lift the parking brake lever, make sure that the rear wheels are locked by the parking brake and depress the brake pedal two times.
For the first time the free stroke can be large, the second one must be normal.
If so, then a large clearance in the rear brakes.
I wish you success!
