Need help with 78 e150 caliper.
Getting ready to replace pads and rotors on my 78 e150 today and when I go to pull the caliper off, all I find is one bolt on a braket at the back of the caliper. After careful consideration, I took it out. At this point I still don't see ho I get the caliper off of its mount so I can remove the pads and rotor. I am used to more modern systems and cars. Am I missing something? Will I need some special tool made of unobtainium?

OK, I got it....I am just not used to doing work that requires a hammer. LOL
Now if I can just get it to maintain pedal pressure. The master cyl. is full, I have new pads and rotors up front, new drums in back, and new adjuster hardware in back. I have made sure the drums were adjusted out so they apply fully. I am currently getting 3 inches of pedal travel before noticable engagement. I have just gone out and given it a good run and a few hard stops from 50-60 mph to bed the new pads in. I don't see how I would have air in the system, but maybe I will try a 4 wheel bleed tomorrow.
Any other ideas? I hope I don't have to replace the master cyl.

Though you adjusted them, I think the rear shoes need to be adjusted more.
One way I do it, is apply the parking brake 1/3 of the way down, then adjust the drums until they lock and can not be spun. Then release the parking brake, then spin the wheels to make sure they freely move. Then apply the parking brake all the way. They should hold the truck when gas is applied in 1st gear.

Thanks, I'll look into that. Just so you know, when I adjusted the rears before putting the new rotors on, I set them so I could just barely get the drums over the shoes. I would think that if any more were needed the self adjusters would take care of it. I'll have to put it back up on stands and see what I can do. Now all I need is the time to do it.
