OK now here's what you do to adj. the brakes properly on a posi. First loosen the emergency brake cable a lot. Pull the levers (on the shoes) on both sides to make sure the e brake is fully off. Then one side at a time and only one brake drum at a time. After you have loosened up the e brake push the shoes together to seat them, use the drum to help center them. Rotating forward only adj. them to a slight drag. Do not adj. the e brake yet. You must drive the car for a few miles 5-10 to seat the drums to the shoes, at this time the pedal will be low so be careful. Return to your shop and do it all over again. Your pedal should be right on top, high. Test drive again if all is OK then adj, the e brake if not re-adjust again till you get a good adjustment. You may not get it correct the first time as there is a certain feel to it.so just re adj. again as required. Again, the last thing to do is adj, the e. brake.
