To adjust the front brakes the front wheels will need to be removed.On the right front wheel, looking at the drum with the wheel off, to tighten the front adjustemnt,The screw driver will be moved from top to bottom (will turn wheel clock wise)on the front slot and bottom to top on the rear slot.The L.F. wheel will be just reversed.Just adjusting the fronts will probably bring the pedal up to a reasonable height.Common,especially if the brakes have not been adjusted for a long time , for the adjusters to be froze.Also common for the wheel cylinder pistons ,at least some of them, to be froze or sticking in the wheel cyl. bore.
The rear will be adjusted thru the backing plate.Remove the adjusting hole plugs , if they are still there, so you can see the adjusting wheel.Will help guide you to see what your aiming for, (same for the front)......When looking at the rear adjusters from under the car , on the right side, the front adjuster will be turned "tighter" by going up with the SD handle-down with the rear.-just opposite on the left.If you are going in the correct direction the brakes should begin to drag after about 20 or so clicks.Hope this will help you to picture what you are trying to accomplish.
