Re: Brake Drums
Did you get the shoes sized to the drums?
Did you put new drums on? Did you center the shoes on the backing plate? New linings on the shoes may be too large for new drums. You can also get thicker linings which might be too much for your set up. It is hard to know the correct answer without more information. Critical to getting full contact between the drum and the shoe, the shoes are sanded to match the diameter of the drum. After mounting to the backing plate the shoes must be centered when set to just under the size of the drum. It is important to understand as you expand the shoes at the adjuster you effectively move the center away from the adjuster. |

Re: Brake Drums
sometimes the threads on the adjusting wedge get rusted or packed behind with dried grease between them and the backing plate so you think they are backed all the way off, when they really are not. It might mean removing the adjusting wedges, cleaning out the old grease and dirt and chasing the threads, then re-installing them with fresh grease. But you can try Kroiling them after removing the shoe springs and working them back and forth until they move back. Just 2 or 3 full revolutions back can make the difference.

Re: Brake Drums
Easy to check.... If the adjuster was turned all the way out, and then assembled with the brake pins and shoes, sometimes the brake adjusting shafts are sitting on the high spot of the adjuster. Turn the square back and forth a few times to make sure you are sitting in the lower part or the groove. Just a thought, guess how I learned this!
