While working on the quad bag thing, I have run in to a problem with the rear brakes. There is a flat bar that goes across from the rear shoe to the front shoe. On the rear wheel it is a flat bar with no spring. On the front wheel it is a formed 90* bar with a broken spring. They are both worn from rubbing on the hub. Can I replace the formed bar with a flat bar? If so, where can I find these? I'm thinking they should be the same as a 1 ton brake. I have GMC part numbers that I will try at my local parts place. I have two pictures I would like to send to anyone that could post them here.
Thanks again, everyone.

Other than the brake cylinders both rear wheels should have all the same hardware. The part you are referring to is the strut or parking break link. It should be angled and have a spring on one end Here's a diagram:

Yes, that is the part in the photo. The front wheel has a formed piece. I'll see if I can dig up two of those flat pieces and springs.
Thank you.

The springs come with a new brake hardware kit. If they are broken/missing I would recommend replacing all the brake hardware as it is indicative of the condition of all the springs. It's cheap insurance. JimK has the kit for $13 for two wheels:

I wouldn't be surprised if Jim could dig up the struts for cheap too. - Dave

David,

I just posted a message titled "How to upload photos to the GMC Photo Site." It is very simple to sign up and post photos.

Ya know, there are a lot of GMC'rs that have converted to rear disc brakes and may have those parts just laying around. Anyone??

I have two sets from changing over the front axle, but am now 1200 miles from home with no plans to be back until April.

I have to do some more looking. It appears that the '73 and '74 rear brakes were upgraded with later model shoes. I have a '73.

Harry,

The flat link is early version, the bent and bowed is later version.

Check this tech article for more info.

Now is your chance to get it right.
