1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!

Alright, I’ve finally admitted defeat on these brakes. I’ve been through this system a hundred times and can’t come up with any reason why it won’t function. The new hydroboost unit should be here soon, and I ordered a Lugnut 4x4 rear disc swap kit with the larger 76-78 Eldorado calipers and all the upgrades, as well as a new Leeds disc/disc proportioning valve. I’ll have to swap out the master cylinder again too, but I hope this will be worth it to finally get the brakes where they should be.
