[QUOTE="davidd, post: 44562, member: 1177"] Eugene, Welcome! The brake works much like a side pull brake on a bicycle. It will pull on one side and you want to adjust the other side so all of the shoes, left and right, are hitting the brake drum at the same time. To start, make sure that the cable is pulling the left and right levers on the brake at 90 degrees. Much lower or higher and you are giving up the best leverage. If you have trouble getting the lever in exactly the right spot, take the nut off and there is a serrated washer underneath. If you index it 90 degrees different, it will change the adjustment slightly. While doing the adjustment, I try and make sure that when the lever on the brake is at 90 degrees to the cable the shoes are extremely close to full on the brake, namely, the less travel in the lever on the brake the better. Once the levers on the brake plates are as good as you can get them attach the cables and see if you can adjust them so they will pull both left and right levers the very small distance so they reach full on at the same time. You may encounter lots of little problems. The cables may be stretched or not correct. The shoes may be worn and not trued to the drums. The return spring or springs might be fighting you, you may have adjusted the levers on the brake so that the shoes on one or both sides are so close the the drum that they are on all the time. Just ask more questions and try to eliminate the problems one at a time. Good Luck David [/QUOTE]
