Been doing some reading on the forums here about the hydrovac and brake cylinder rebuilding, however I still have a couple questions if anyone happens to know.
First: is there a supplier out there that has complete front wheel cylinders available for these big bolts? I was able to find rear but not front. (Have not pulled anything apart yet so dont know how pitted my wheel cylinders are they may be salvageable. Just curious worst case scenario)
Two: are the 1 ton master cylinders the same as the regular pickup trucks or are they specific to the larger trucks?
Three: this one is region specific, anyone near Chattanooga have a preferred parts supplier that knows a little bit more about these machines beyond Oreillys etc?
Appreciate any intel you guys might have!

Napa and Rock Auto should both have rebuild kits for the front wheel cylinders and the master cylinder. I am not sure about the whole cylinder. Browse or search the big bolt forum though, there was a thread on this exact topic that came within the last week or so. Also, do you have a 55.1 or 55.2 (AD or Taskforce truck). They made a model change mid-year in 55. | | | | | Joined: Feb 2016 Posts: 1,989 'Bolter | | 'Bolter Joined: Feb 2016 Posts: 1,989 | You won't find an exact match for the front wheel cylinders, as 69Cuda noted read some of the posts in the Big Bolt forum. The casting number on the wheel cylinder will dictate which rebuild kit to use. The master cylinder is not the same as the 1/2 - 3/4 ton as 69Cuda wrote.

I did re-read the post you guys mentioned. The first time around I did not catch where someone talked about the front cylinders being discontinued. Will start to pull some stuff apart and see what my casting numbers are.
Thanks

Do a google search for wheel cylinder sleeving...I know White Post Restorations does it, but there may be others as well. Mike B  | | |
