I am wondering how to tighten my emergency brake tensioner? I have tried finding info online for disc brakes but all I find is info on rear drums. Any suggestions or knowledge would be much appreciated!

The following is from the ZJ FSM: (*the fig.s or diagrams didn't come through, but it's for disc brake equipped ZJ's. The inside horizontal surface of the rear rotor is the braking surface for the e-brake shoes).

PARKING BRAKE CABLE TENSIONER
NOTE: Parking brake adjustment is only necessary
when the tensioner, or a cable has been replaced or
disconnected for service. When adjustment is necessary,
perform the following procedure for proper
parking brake operation.
ADJUSTMENT
(1) Raise vehicle.
(2) Back off tensioner adjusting nut to create slack
in cables.
(3) Remove rear wheel/tire assemblies and remove
brake drums.
(4) Check rear brake shoe adjustment with standard
brake gauge. Excessive shoe-to-drum clearance,
or worn brake components will result in
faulty parking brake adjustment and operation.
(5) Verify that parking brake cables operate freely
and are not binding, or seized. Replace faulty cables,
before proceeding.
(6) Reinstall brake drums and wheel/tire assemblies
after brake shoe adjustment is complete.
(7) Lower vehicle enough for access to parking
brake lever. Then fully apply parking brakes. Leave
brakes applied until adjustment is complete.
(8) Raise vehicle and mark tensioner rod 6.5 mm
(1/4 in.) from tensioner bracket (Fig. 84).
(9) Tighten adjusting nut at equalizer until mark
on tensioner rod moves into alignment with tensioner
bracket.
(10) Lower vehicle until rear wheels are 15-20 cm
(6-8 in.) off shop floor.
(11) Release parking brake lever and verify that
rear wheels rotate freely without drag.
(12) Lower vehicle.
NOTE: Do not loosen/tighten equalizer adjusting
nut for any reason after completing adjustment.

PARKING BRAKE SHOE ADJUSTMENT
(1) Remove wheel and tire assemblies.
(2) Secure rotor with two wheel nuts.
(3) Remove rubber access plug from back of splash
shield.
(4) Insert brake tool through access hole in splash
shield (Fig. 85). Position tool at bottom of star wheel.
(5) Rotate star wheel upward in counterclockwise
direction to expand shoes (while facing front of vehicle).
(6) Expand shoes until light drag is experienced.
Then back off adjuster screw only enough to eliminate
drag.
(7) Install plug in splash shield access hole.
(8) Install wheel and tire assemblies.
