* Drum brakes: This was the most common type for that era. They are comprised of a brake drum (a cylindrical metal housing), brake shoes (curved metal pieces that press against the inside of the drum), and various linkages and components to activate the brakes. They're relatively simple in design but less effective than disc brakes in terms of stopping power and fade resistance. The drums would be relatively large in diameter, reflecting the truck's size and weight.
* Possibly (less likely) Disc brakes: While less common on F-250s of that year, some higher-spec models or optional packages *might* have featured rear disc brakes. However, drum brakes were standard. If it does have rear disc brakes, they will look similar in general design to any other disc brake setup – a rotor (a metal disc), calipers (which clamp onto the rotor), and associated hardware.
To know for sure what your specific 1968 F-250 has, you should:
* Look at the truck: The easiest way is to remove the wheel and visually inspect the brake assembly.
* Check the owner's manual (if available): The owner's manual should specify the type of brakes fitted to the vehicle.
* Check the vehicle's documentation: Service records or other documentation might list the brake type.
* Check a parts catalog: Using the VIN number, you can find parts catalogs that will show the original specifications for your truck.
Without knowing the specific configuration of your truck, it's safe to assume drum brakes are the most probable type you will find on a 1968 Ford F-250.
