I have a 86 K5 Blazer. Recently swapped a 90s 14 bolt in, initially had almost zero brakes, changed the master to a 1 ton and changed the proportioning valve. I can at least stop now but nothing id drive in town with. So when I drive in reverse and slam on the brakes, my pedal hardens a ton. Then shortly after goes back to being spongy.
When I changed the axle I adjusted the shoes to barley touch the drum. My only assumption at this point is that the shoes are adjusted too far out, so when I brake in reverse they try to adjust before going back to normal. I'm really not sure, I wanted a second opinion before tearing everything apart. Thanks in advance
