A surge coupler for actuating hydraulic drum brakes, such as Titan # T43397007K, can be pumped for purposes of bleeding the brake lines by using a 2 x 4 or similar piece of lumber to compress the coupler.

The linked photo shows the general arrangement for doing this, which includes using the trailer safety chains for leverage.

The complete instructions for Titan coupler # T43397007K are linked and these include a detailed procedure for bleeding the system using this wood-with-chains method.
