    gimme a brake

    I got the brake stuff today, took off drum with my electric chicago 1/2 impact.. 12 bolts with spacer.
    got drum off .. it was snug.
    I bought the wrong pads.

    old brakes are perfect.

    the grinding noise is unknown. I saw some marks on back plate.
    I am thinking now, the brake line the inspector pointed at was not even flowing enough to grind a quiet spot.
    pads are more than half, and not even the soft kind.

    Will keep it going as is..
    slamming on brakes and using them aggressive once and awhile should machine a sweet spot.

    another thing to consider is welding the back end frame to harder, may be changing side alignments on pad and back plate and drum

    whatever it is, not serious... I sure do have brakes.

      more brakes
      I am not sure why I think my truck has the big dadday 11 inch brake
      ordered the right shoes this time. Same towing heavy duty by Centric. 10.25

      the grinding noise may be a new alignment on 12 feet wheelbase... long rails.
      I love it when I do that.
      me and my little booger welder altering 21 feet of frame rail

      long wheelbase short... I may not need new pads. I inspected and found no errors.
      some backplate scrub, nothing more.

      where we have had 4 feet of rain in a few days there may be rust exfoliation on the young bendix..scrubbing its way to clean.
      I'll rip into passenger side to know I inspected both sides of truck.


      this handy 1/2 inch ratchet on the little 2 stroke generator even had a neighbor walking by declaring clever.

      I had 12 bolts to take out... due to the spacer.

        the numbers of the devil

        they jumped out at me, like a vampire in a dungeon
        happens all the time.

        identify the vortec.. 96-99

        878 = 305
        880 = 350
        this is near freeze plugs, very easy to get at

        nice to have this verified.
        the stamp on the back is genuine vortec.. that is all the info I had until today.
        I could not read the stamp.. could not reach in to clean enough.

          shoe swap

          perfectly worn. Sometimes i love back brakes.

          Click image for larger version  Name:	DSC01914w.jpg Views:	1 Size:	245.9 KB ID:	1250262

          there was only one pad like this due to an old ebrake ride. I spotted it when changing drums a few years ago. I figured 20k miles left...
          it went to 25k+
          this scratched for 2 days.. drums in great shape.

          got the centrics in..and now earning that self adjuster.
          I found no external manual way to adjust brakes.. truck has to earn that snug position by itself.

          oh well.
          popped a wheel cylinder slug out, slapped it back together and called it good.
          thinking old school with these is a treasure.

          the older cylinder guarantees a self bleed with no measurable leak. I use them until failed. I keep two new ones on standby.

          first ride out already has a luke warm on the drums.. did not go too far turning down adjuster. it should click its way back in some time.
          I also have an awesome trick for the Very strong ebrake spring.. it is use of a universal trim tool and vise grips.

          I like when memory comes back.. I first remember this chore in the 80s. I have done it so often, you would think I was hacking my way through it... 2 hours total, part of it was a break for some coffee.

          I also quit smoking. no problems at all going to a safe vape brand. No crazy flavors. "Njoy" has been around for 12 years. not sure who pioneered the vape stuff, but I was sure to find a reputable one.

          no desire for cigarettes at all now. 25 years, and done smoking... very simple.

            the b52 at loring
            got slightly lost...
            figured I had all kinds of time.

            the legendary run with cruise at 90 something flowing along with other traffic..
            one hour to houlton from lagrange. I do not recall how many times I have done this.
            twice in one day is the norm if I do...

            Click image for larger version  Name:	DSC01917w.jpg Views:	1 Size:	197.7 KB ID:	1250310 somehow this became a source for a meme on facebook.
            very annoying.

            saw the buff flying around, but it had made its flyover and was on its way...
            I made my way back home.

            Truck did very good.

            I looked to the left and right before stepping out at a tim hortons. Had to be careful.. french in the region. Very scary.

              it only does 95.. for an hour at a time
              Click image for larger version  Name:	DSC01919w.jpg Views:	1 Size:	275.3 KB ID:	1250375 not too bad for the speed. I used to have vehicles with broken plastic pieces after the 90mph run.. I am lucky to have only hit two birds with this in 5 years. Did not do any damage back then either. The screw on the bottom.. if grill is not tight the lights fog up in ways maine likes to dish out. August it begins.. won't end until next year. Behind the grill stays warm very much on purpose.. it is just for the lights. Heat comes from radiator

              I am glad to stretch this thing out, for the purpose that haunted me since my first ride down the big highway when I was 15 in the 80s.
              3 speed autos were still the thing...carburators.

              65mph was brand new speed limit in rural I-95 maine.

              My neighbor Tim had a truck with a 327, short bed. manual trans for free, he thought he was getting a 4 speed.
              it was a 3 speed overdrive.

              by the time it hit fourth, you'd think we was in a nascar race. Tall rear gear.. assuming 3.42 or taller.. 3.08
              even with the lightweight truck and original 700 to 1 compression dome pistons shaking our teeth... it took a bit to get into that overdrive long after the needle was buried. the tires grumbling their imperfections.

              it turned out to be the future anyway.. we all do that today.

              I could not wait to find this truck I have now.

              the 314 mile round trip was 18.75 mpg... hanging just shy of speed limiter for more than 90 miles up, and 90 miles back on the highway.
              the rest was secondary roads. No letting off on the highway.. creep up on the limiter, set the cruise to keep it from kicking in.

              I am reminded why little was out a long long time ago.

              Today following some sideways engined vehicle at the same speed in a row of 3 or more is not unusual at all.
              A strange but true fact.. I know when I am behind automatics. they all have a pause to let off every 20 something miles.
              The whine of overdrive direct could go on forever it seems, in comparison.

              Rest in peace Tim. I wonder if you were given a glimpse of what was to come, because you weren't going to be here to see it for very long.
              the last time I spoke to him, was the first time he saw my truck.
              hurst shifter, he knew it was manual without looking.

              "Nice truck man" he rarely said nice things. I think he knew some of the reasons I had that truck in the first place.. a lingering memory since we were kids.

              back to chores..
              the new brake I installed needs to be taken apart again. the auto self adjuster is taking so long the brake light flickers even after a bleed. the reset to relaxed is too relaxed. I'll have to man handle it myself and wedge the drum back on carefully... a bit tighter.
              may as well throw on a new wheel cylinder i have kicking around as well.

                drop hitch
                crazy as a 4 bolt hitch
                not really a saying, made it up myself.

ID:	1250696 added the two smaller bolts near license plate. the bolt holes were already in the hitch below
                I simply want the half ton limit on a drop hitch.. without the whole receiver from hell.

                found some drill bits that got through the carbide tungsten lightning steel aged at a quarter century
                broke 4, dulled 3... but the broken bolt extractor set worked good. Just had to let cooldown every few minutes.

                the deck squashing into that stainless outer bumper cover is just an extra lamination. it is a nice guage... beyond 16 for sure. Appears to be an 1/8th inch
                I think I can cheat the tongue stamp of 400# to a bit more now... but don't tell anybody.

                it is actually welded etc.. I think I shared all the back end chores. Ready to go.
                the skin at the edge rusting is thinner than where the bolts go through. Very tricky business... the appearances tricking us all by factory engineering it alllooks like one flowing uniform piece, and it isn't..

                  cryogenic treating

                  excellent video.
                  I babble in my own terms to describe cold steel shaking the ground from the north (an old trucking legend)

                  anyway...
                  here is some science out loud.


                  now in a vehicle with 400k miles, 23 years.. a yearly hit at 20F below or colder, back to 130F pavement, 12v cathode anode losses and gains,
                  welding etc and heat cycles..thousands upon thousands of them.

                  what does an old vehicle become? even if it is rusted.. there is some serious stuff to revive with heat and new metal and welding

                  my place gets so cold, I need july to weld a long rail to avoid local hardening (brittle break) with a very slow cool into gods quench of the below zero winter...and then go a whole year again the same cycle.
                  this guy puts some stuff into view and some words.

                    dominoes

                    looking over the rear hangers.. the passenger side was my focus earlier this summer. got that squared away after torturing it with an air chisel and a grinder.
                    I see the rear left s at an angle not quite right and wiggled it around...

                    got another summer chore I have to get done quickly. I should have guessed symmetry, but the lft side was looking good this past May.

                    I'd like to get the old hanger out of there entirely.. seems it needs a plasma cutter and a torch.
                    the ugly hanger doesn't matter much, the wimpy tail it is attached to does.

                    I am going to make both of them 6 bolts like the front hanger...already beyond half ton, may as well go all the way.

                      monarchs are flying.. welds aren't dying

                      I like that saying. I'll call that one legit.
                      got a frost warning for tonight..
                      I have never welded at framing this late in the year..
                      hurricane odors lingering, a monarch butterfly hanging around my work.
                      So I manhandled the last hanger, driver side rear area.
                      it turned out to be bordering a mishap

                      Click image for larger version  Name:	DSC01954w.jpg Views:	1 Size:	179.3 KB ID:	1251181

                      took a hammer to it.. some shatter, but staying strong where it mattered.
                      I love this trucks aging frame.

                      busted out some frame, found prior welds needing attention.
                      I am assuming the monster destruction test was hauling to the mill for my dad.. simple 200 pound beam.
                      better than a hammer to test things out. That road was so rough, he did not want to take the peterbilt through it.

                      Click image for larger version  Name:	DSC01955w.jpg Views:	1 Size:	305.0 KB ID:	1251182 terrible photo as usual. you can see the dab of weld on hanger..
                      it is held on normal, i just don't like how ugly it is. this removes the same as before, grind out rivets.

                      added about 1.5 feet of flat stock.. 3 inch wide I believe
                      and it took in 1.5 pounds of weld.

                      ready to go another round with a maine winter

                      A strange but lucky new welder from harbor freight never used..
                      I have not seen this much power yet from such a small welder.
                      not sure what is going on there.. another update to the internals i guess.

                      even got some melt to recover some older steel. Very nice.


                      with embarrassment I can admit the occasional rumble and shake in reverse had a source...
                      the driver side rear was flopping around for all 4.5 years I have had this.
                      Elusive until it rears its ugly head. I even towed my car and boat with it..nothing failed or revealed anything.

                      I do not like the condition of rear hangers..but they are hanging in there.

                      I may be saving for a plasma cutter.. that will be my first chore if I do. I already have the new hangers.

                      I am in another 5 hours or so.. just the rear left today.
                      this old half ton is back to full tow for sure.

                      total for weld is about 80 pounds of steel and 7 pounds of wire.
                      on the scale I am strangely guessing 1000 pounds heavier.. physics.

                      edit: last night hit 40.1 F
                      we got away from the early frost by some degrees.

                        39F was the low... and my thermometer reads high

                        time to slap some paint on the old frame.
                        winter is coming.

                        the white admiral is the northern butterfly. the monarchs are gone .. too cold.
                        but these guys, they can go below freezing and still wake up in the sun. A source of interesting science for those into cryogenics.

                        back to truck work.

                          tail gate party

                          my dad turned in his 2016 for a 2019 half ton. Drive it around today.. looking it allover.
                          x31 package.
                          for the first time in their history, gm has given up on the apron type front end. First thing I noticed is the fender being just a single piece of sheet metal...and alrge unibody type arm angled in, like what you see under a mustangs hood
                          I also found my custom rockers are near identical to what the 2019 does right out of the box...nice and fat up front, surrounding door bottom.
                          super smooth shifting. Great power.
                          bumper hitch now at 1000 pounds tongue, which usually equates to 10k pounds or more for hauling.. and it is all one piece. No more separate silly ass hitch to think about
                          for other framing changes...I found some square tubing where some round used to be, and one more extra... which gives me an idea about mine.
                          suspension hangers are welded under frame now as well.

                          I laughed. Everything I griped about and went custom on with my 96 is now built into a 2019 model.
                          very nice truck.

                          Today I finished my ugly hangers and fixed tailgate hinges. Now shuts like a door, don't have to fidget around with it.

                          rugged ride home.. I got all four spots on the two hangers down low. I may even add some brackets to simulate the 2019.


                          full tow, super smooth ride. It really noticed the hanger welds.
