I ordered all my brake parts for my B3-D from vintage power wagons, they are all the same as on my power wagon, except lines and hoses.

cool thanks. Power Wagon? I am envious. I had a very nice 1/2 ton WWII carryall for a while about 12 years ago and let it slip away...

I am in the process of the same on my 54. Located proper wheel cylinders for my fronts in Dorman at Rock Auto, about $35 each new. Front shoes and correct rear wheel cylinders were from Packard Industries/Kanter for $48 shoes and $64 each wheel cylinders (wholesale). Rear shoes were an ebay find. Will be converting to a dual master from a 70's one ton van if all goes well and all new lines in NiCopp line. Those floating rear shoes with the Budd drums are very unique. If need be I can supply the part numbers I used and the FMSI numbers for the linings if that helps, may be same as what you need, not sure.

part numbers are always helpful and appreciated.

I pulled this info off my Blog so excuse the writing style. This is all for my 54 so I can not say what is correct for other years. Pictures I have seen show what looks to be the same odd rear brakes on the Pilothouse one tons as well. I don't have my factory parts book here for any additonal part numbers but I have not been able to cross reference those to anything new.

Front shoes are 11″ by 2″ FMSI number Shoe 98 drawing 1550 catalog ref. no 192. Everyone seems to list these as part number 98 (TS98 at NAPA, though not available, BS98 on ebay, etc...) These were located at Kanter auto products/Packard industries.

Front wheel cylinders are Dorman 17789 1 3/8″, new manufacture. Very reasonably priced, can be had by anyone who deals in Dorman. Got mine at Rock Auto.

Rear shoes are 14.13″ by 2″ FMSI number Shoe 107 drawing 1765 catalog ref. no 1224. This was an ebay find in Grey Rock brand that was listed for a Pilothouse era truck.

Rear wheel cylinders. These were tough. All current manufacturer catalogs and older paper catalog listings I could find have them listed wrong. All the info I could find currently calls for 1 3/8″ or 1`1/2″ bore cylinders depending on “early or late L140 axle”. This is what the catalogs say. This is completely wrong! The correct wheel cylinder on the rear of this truck per original factory info is 1 1/8″ bore. Now, I can say for a fact (I ordered and returned all the listings I could find) that the 1 3/8″ and the 1 1/2″ wheel cylinders will physically fit the backing plate as will the front ones fit on the rear, but I guarantee you will have a lower pedal when you are done and the braking bias front to rear will be off. In no modern catalog of major manufacturers is there a replacement for this that I could find. Maybe there is one out there, but no listing exists for the part number. The factory part number also does not cross over to anything. Luckily, Kanter/Packard had them, part number 17741. I could not locate this part number in any current new manufacturer line either. In case you are wondering, I could not have the rears sleeved because there was one 1 3/8″ cylinder on the left rear and a stepped bore 1 1/4″-1`3/8″ cylinder (Power Wagon Maybe?) on the right.

I have not been able to locate new replacement drums at any source. Time will tell if this will be an issue.

Lines will all be replaced with NiCopp alloy line. I bought them from Lee Auto Parts/Autowares. Any Bumper to Bumper retailer can get this. It is distributed by AGS under the PartsMaster name. Part number is CNC425PM for 1/4″ 25′ roll and CNC325PM for 3/16″ 25′ roll. It is less money than Cunifer line and easier to get. I will do them once and never have to do them again. This stuff is for life and very easy to work with.

Hope this helps a little.

My B3-D has stepped bore cylinders all the way across, and seeing as how the master is the same as on a power wagon, the same slaves make sense to me.

not to hijack, but anyone been successful yet in upgrading their 1 ton to discs?...I might have to go back to stock if I can't get this thing figured out...or an axle shipped up here to the Great White North
