1970 Bronco Drum Brakes

[ToddJerad]

Hey guys,

I am new to the forum and think it's really great.

I also have a question about my 1970 bronco 302 project. I have been fixing the truck up and now I have come to the front drum brakes. I would like to put new cylinders and hardware on the existing drum brakes, but cannot seem to figure out how to take the casing off. I removed the 4 wheel drive hub switch that controls 2 wheel drive and 4 wheel drive but after that i am lost since I cannot pull the case off. Is there a diagram or easy way to do this? Thank you guys again for your help.

Todd

By casing do you mean the drums? If so you need to back off on the adjuster to relieve the shoe pressure on the drum. Then it will either come right off or just give it a couple of whacks with a rubber mallet.

Good luck,

I apologize for my terminology, but I am talking about the part you see when the wheel comes off with the bolts for the wheel. After I take the hub off for the 4 wheel drive, do i not need to remove anything in the center? It should just slide off when the pressure is backed down. Thanks for your response.

If the brake drum has never been removed from the bearing hub (proper terminology is being used here, if you don't have one, you should pick up a service manual...)

Then you either need to remove the whole assembly as if you were going to perform a wheel bearing repack, or you will need to find a swedging tool. The factory wheel studs are pressed into the bearing hub and the drum from behind and are then "crimped" into place. That crimp is called "swedging" and will need to be removed in order to access the brake shoes and wheel cylinders without removing the bearing hub.
