I have a 1926 with a Ruckstell axle. It has 8" drums. Is that correct or has someone changed it to an earlier axle? I was told all 1926 T's had large brake drums.
Someone used what they had, all 1926 and 27 had large drums. Unless you are going to pull it to rebuild, I would leave it as it is. If you don't have them I would however recommend (very strongly) adding aftermarket rear brakes.
If you are planning on pulling it you could try and swap the Ruckstell side housing with someone that is looking for the early style and replace the other side with the correct housing, the right side is just the standard housing. Of course that also means different radius rods, brake shoes and brake rods.
My 1926 Ruckstell has 11” drums.
Per Ford Service manual for the Improved Car par. 1221 Brake drum has been increased from 8” in diameter to 11” in diameter, the width of the drum being increased from 1.812” to 1.843”.
Thank you for the replies
