I'm just so frustrated in getting my rear brakes to hold when applying the EB pedal. I thought it was fine, but it really wasn't holding that good. So today I decided to get this done right - finally. I jacked up the rear of my bronco and removed both drums. I want to make sure that the rear shoes and the mechanisms are expanding and working properly when applying the EB. So I recorded a few videos to show what happens when applying the EB. Can you all take a look at this and let me know your thoughts are ? Good to be back and thanks!

Mine is the same way I have to mash it as hard as I can to make it hold the bronco from rolling. I wish mine was better too. Looks like it is working right

Well I’m not the only one I guess. What gets me is that when I put the drums on I get to the point of a slight drag when adjusting the drum star wheel. I then put the E-brake on while the rear is still on stands and can’t even turn the wheel by hand. So now when I pull up my driveway and apply the E-brake the bronco will roll back. I don’t get it because I know the shoe is expanding properly - shown in the two video. So, do I adjust even more with the star wheel. So I’m basically adjusting the drums to the point where they don’t turn. Doesn’t seem right....

Its far easier for the weight of the truck with the leverage of the wheel to turn against a brake than for you to turn it. Even if it feels very solid it may still allow the truck to roll. As the brake drums wear the pads will sit in a groove. The end result is a lip on the end of the drum. If you adjust it so that this lip just fits over the pads they may not be close enough to the drum once installed. They're supposed to self adjust but I've yet to come across a drum brake car that actually self adjusted after a brake job. I like to adjust them with them completely assembled, both for ease and to rule out the lip as a source of problems. Takes some practice and feel but you can do it pretty easily, I like to adjust them till I just start to hear them drag then back off a bit. It could also be shoes/drums that are not in good condition, or an issue in the E brake mechanism. There's a sacrificial piece in line with the cable that will stretch if too much force is applied, so if with new shoes and properly adjusted brakes the pedal is still going too low before it grabs I'd look at that.

Thanks for the advice. I adjusted the shoes today by expanding them ever further out. Everything installed on my Bronco are new parts. Cable, drums and hardware. I’m going to pull it out of the garage tomorrow to see how it holds on my driveway. I’m assuming with all the minor brake show adjustments, it will have to hold at some point. Thanks again....

Here’s going to be the tricky part, does the pedal move any distance before the parking brake arm? There’s an adjuster under the truck to adjust at what point the arm moves with the leaver, it is also connected to both sides at a splitter, are they adjusted snug and at the same length at the splitter?
