Thanks for the info! Yes, the rear wheel was raised above the master cylinder.

Going to be a stupid question but how do you check the master cylinder for fluid on this truck? I mean is there a fluid reservoir like on modern trucks or a fill hole somewhere? If there is no fluid, then I need to add fluid and then bleed the break system? If I need to add fluid, what kind of fluid does it need - regular brake fluid?

Re-man the rear brakes is on my list to do soon. I have been reading on how to perform it on this site. My concern is over knowing if the drum needs to be replaced and where to find parts.

Thanks,
James
