Which brake drum (size)?

[GJCruiser]

Brain fart moment. Replacing rear brakes on 72 FJ55 and was surprised to note max diameter noted on drum as 292 mm. Attached a photo of my chassis manual. How do y'all interpret this. FJ55 should be 292 or 297. What about Fire truck? That wording confuses me. What should be spec for non-Fire truck? I always thought FJ40 and FJ 55 drums were same. I've not noticed drums at 292 max. Where do I source these?

Thanks

SOR doesn't seem to differentiate between any semi-floating axle from 1963 - 1980 and the attached photo for their listing indicates 292mm. So what does above manual mean--- FJ 55 is 297 but only if Fire truck and 292 if not Fire truck? I just never studied that piece of the manual before. Thanks.

Yup! 11.50 inches max

what year is your manual from? There are larger Non-US drums on 75-up 40/45/55 etc. they are only a little bit larger diameter (I haven't measured how much exactly) but use a much wider brake shoe

My manual is for a 1976. All the vendors I shop indicate the same drum for FJ40/FJ55 so I assumed they were all the same. I still don't understand the wording in the manual. On to sourcing the the 292 mm drums. Thank everyone for help.

don't understand the wording in the manual.

Try this. Same thing but different.

I put someone's fire truck VIN into ToyoDIY a couple months back and it took the VIN, recognized it as a fire truck and I assume showed the appropriate parts diagrams. YMMV

Looks like J Mack has you sorted regardless.

Duh! Why didn't the manual just say that! Thank you.
