I can't say that i've wroked on every tandem cylinder equiped vehicle ever made. So there mite always be exceptions. BUT USUALLY the port nearest FRONT of cylinder is for the REAR brakes.

Also there is at least two different internal piston designs.

Regardless, back off the shoe adjustment on all 4 brake shoes so that the shoes are very loose out of adjustemnt. Remove the line from the mc that feeds the FRONT brakes. Install a hose or tube into the same port and place the other end of hose into RESERVOIR of MASTER CYLINDER. Make sure the mc reservoirs stay full of fluid. MAKE SURE the end of the hose placed in the mc reservoir is always below the fluid level. We should be dealing with the MC port closest to front of car and furthest away from brake pedal rod in this case.

Now bleed the REAR brakes.

Reconnect the mastercylinder brake line.

Repeat above process for the bake line that feeds the FRONT brakes.

Adjust all 4 brake shoes as per manual.

Vacuum bleeders are makeshift at best. Bleed brakes with a helper. When bleeding brakes using a helper NEVER UNDER ANY CONDITION release the brake pedal while the bleeder screw is open. THE BLEEDER SCREW MUST BE CLOSED IF THE BRAKE PEDAL IS RELEASED even a tiny amount.
