Radius Rod Loose/Rear Brake Drum
Hey Guys, I just discovered the Left/Rear radius rod bolts are very loose at the backing plate. I can`t tell if they have elongated the backing plate holes(which is where I assume the bolts go through) and if not what would I need to replace in any case. Where can I purchase new radius rods if they are available? Secondly, can any drum puller be used to pull the rear brake drum, or does the Model A require a special puller?
Thanks Richard/Maine |

Re: Radius Rod Loose/Rear Brake Drum
It depends. Sometimes the rear drums come right off, other times you don't think they ever will, not with ANY kind of puller. Start with a simple three arm puller. You can always graduate to tougher measures. Whatever method or tool you use, leave the nut on the threads a little so the drum doesn't come flying off and do you damage.

Re: Radius Rod Loose/Rear Brake Drum
the bolts that hold the radius rods to the backing plate fit through a sheet metal grease shield. The holes in this get worn through. Then the nuts will bottom out on the shoulder of the bolt before thoroughly clamping the backing plate and radius arms. If everything else is not too worn, replacing the grease shield will provide enough shim the allow the nuts to be tightened. However, by now the nuts are probably worn down too and it is possible the backing plate and radius arms will show wear. You will have to inspect them after disassembling to determine if they can be re used.

Re: Radius Rod Loose/Rear Brake Drum
I've seen flat washers under the head of the bolt in order to prevent the nut from bottoming out before tightening things up. The cotter pin will keep the nut from loosening. If the nuts and / or bolts are worn, the vendors have replacements that work quite well.

BTW, the brake housing (backing plate) was also snug on the bolts but additionally was snugly centered on a lip machined on the end of the axle housing
