I got cylinders and hoses from my local Cat dealer. Pricey like all Cat parts but quality. I haven't installed them yet as I discovered that I need a hefty wheel puller which I don't have.
meanwhile I still use the grader by cutting the hose on the wheel with the popped cylinder and plugging it with a bolt and clamp.

My uncle used truck parts that matched for wheel and master cylinder on a No 12 8t grader. As Cat had used off the shelf parts rather than reinventing the wheel. But 20 years ago many more parts persons that could find things without the year and model no entered into the computer.

Hi Team,
a friend and I recently did the brakes on his 212 and we had our cylinders re-sleeved in stainless steel to save any further rusting issues.
From memory and as said above the parts most likely will be stock, common used, Wagner or Lockheed.

Hi GG,
we used a suitable sized 1" drive socket and extension to fit the hub nut suitably supported at the T bar end on a block of wood to resist slipping off.
An open/standard nut should be fitted on the axle and be flush with its end with some clearance to the hub to stop the hub and wheel flying off and dropping the tandem end on the ground or your foot.
Then we used a substantial bar puller with grade 8 bolts/all thread fully seated home in the hub threads.
Tension the puller bolt or press if you have one.

For really tight hubs at The Dealer we used to leave the wheels on to begin with to support the hub and add weight to assist resistance to the axle via the puller bolt plus the the hammer blows. Also I was taught to jack up the opposite end wheel on the tandem to apply extra resistance/leverage to the wheel/hub being pulled and apply some hammer blows to the puller bolt--hammering a hydraulic cylinder is not recommended safety practice.
We were lucky as is often the case the hubs were loose on the axles.

Scan below is from a Cat Tool Guide, But, you need a more substantial cross bar puller gear than shown in most cases.

Cat have a cradle like puller adapter that uses the puller bolts in the hub and also picks up 4 of the brake drum mounting bolt holes for really tight ones on later counter weighted No12 and 14 hubs that went on tighter than these ones 

Hope this helps.

Cheers,
Eddie B.

Wow, that's fabulous!
A wealth of information. I was going to try to pull it without removing the tire and rim so I was on the wrong foot to begin.
I couldn't find a shop manual for the 212. What's the name of the Cat Tool Guide or is that the name? do you have a pic of the cover?
Thanks!

the light duty puller info came from a hard bound 1959 Tool Guide book and the heavy tooling came from a No12E Service Manual as it is later gear than 1959--Cat Tool Guides are now a blue 3 hole folder to enable replacement of pages for new machines and updates and I do not know the Form Numbers for these.
My old book is Form No 32622-2 The Dash number (-2) is the change level of the publication and the higher the dash number the later the publication.

Cheers,
Eddie B.

Thanks! I'll see if I can get a copy.
I tracked down a 1 inch socket set at Harbor Freight that looks like it will accommodate the big center nut. I didn't know such a "jumbo" socket set existed. I'll add it to my 212 wrench collection. seems every bolt and nut on the 212 is a different size and I've accumulated a pretty good set of big wrenches that a shade tree dilettante mechanic such as myself would not normally have around.
