My brakes work fine with no spongy pedal, but if I want to stop I really have to PUSH on that pedal. It feels like I dont have power brakes or something. Is this normal, or has something gone bad?

I had that issue on the 1986 4wd & it was the load sensing proportioning valve (the thing with the spring behind the gas tank) the 1983 4wd does NOT have an LSPV & stops far better...hmmmm
Also, be sure to check the vacuum line going into that master-cylinder thing on the firewall: that's the booster. If the vacuum line is clogged or detatched, it would certainly cause that problem.
RRTT's experience reinforces a post I made not long ago: these trucks have designer problems, and new ones crop up all the time! It's great we have a place to pool that information.
The greatest gift you have to give to the world is that of your own self~transformation.
so...you press on the pedal & it depresses to "normal" level & it just doesn't stop til you reach the next town...IMG_0001.jpgIMG_0003.jpgIMG_0004.jpgIMG_0005.jpg...i had to replace valve & spring. try adjusting first & see if any change occurs....then bleed...also verify lines are not clogged/collapsed anywhere else.
I'll take a look at my manual. I really hope nothing needs to get replaced. Where did you find your part of that is what is needed? I am not readily finding anything online.
bought mine from dealer....back in 1991...& its is for sale if you need it
