The part I need looks similar to this but it should be a single spring, not two like the one in the picture. spring | | | | | Joined: Dec 2015 Posts: 2,063 Big Bolt Forum Moderator | | Big Bolt Forum Moderator Joined: Dec 2015 Posts: 2,063 | Assuming those are the shoe return springs, not sure if they are the same but, I bought some Raybestos H9226 springs off Ebay for my 1958 6400.

I have one similar on my 59 Suburban. diameter of the master cylinder is too small for a 2-ton. It won't push enough fluid. | | | | | Joined: Mar 2004 Posts: 6,214 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,214 | I don't believe anyone make a "kit" for the big trucks, you would need to pull it together on your own. Your '56 6500 MC has a 1-1/4" bore, so that's the bore size you need to look for. If all of the parts are new you should have many years of good service from the original system. Make sure all of the lines (steel and rubber) are new as they fail from the inside out, replace/rebuild the MC and wheel cylinders and go through the shoes, adjusters and springs. Don't forget to make sure the parking brake is in good working order and adjusted as well.

We, my neighbors and I are getting it ready for the road so we can haul stone to fix our privately maintained road. They are both retired and grew up around these trucks plus one owned an excavation business. They are replacing the brake lines and going through the truck to ensure it road worthy, to date I have been using it around my property and stopping by turning off the engine. lol.  | | |
