Ford 10.25 Shoes

[ZSK]

'97 F250HD SRW 10.25"

I need to do a full brake rebuild. Looking at shoes, hardware, wheel cylinders, getting the drums turned and new parking brake cables. I know the shoes come in three sizes, 2 1/2", 3" and 3 1/2" and being a SRW HD truck I should have 3" shoes but wanted to make sure. I pulled a drum to take measurements and I found 2 1/2" shoes with the drum surface being about 3" wide.

Did the previous person just put in the wrong shoes or did I measure the drums incorrectly? This is a full float axle and NOT the semi float 10.25"

I suspect either shoes fit.

Dodge is like that... also 12" Bendix drums. All the drums will take 3", but most axles only got 2.5" shoes. Easy to upgrade - backing plates, hardware, and cables stay the same.

Id swear 2.5" is the semi-float axle, 3" is the SRW and 3.5" is the DRW. I have 3" shoes in all 3 of my trucks and theyre all SRW axles. u2slow is prob right, tho, id bet both the 2.5" and 3" fit just fine in the same drum.
