    Right adjuster on the right side, left on the left. They are marked.

    The cable goes to the rear. Left and right are mirror images of each other.

    Right and Left.

    Do you have the pushrod from the brake pedal to the master cylinder adjusted so as to have just a bit of slack in it? If there isn't any then the the master cylinder piston may not be coming back far enough to allow the brake fluid to return to the reservoir. After a while the fluid heats up, expands & pushes the brake cylinder pistons out causing the the shoes to drag, making more heat, making the fluid expand more, putting more pressure on the pistons, making more heat, causing the brakes to- eventually- lock up.

    Jeeps aren't really noted for this problem but I've seen it happen on other vehicles after a master cylinder swap..

    x 2 just went thru the same thing, started out with the brake light staying on, first long trip after mc replacement all for wheels locked up so tight I had to loosen bleeders to get home, shortened pushrod and all is well
