F1 brakes
I have mounted complete f 1 brakes on my round back spindels. Bendix # 301917 .my proplem is the new brake drum wont touch the hub because the backing plate hits the back of the drum. Any one run into this? Dont really want to cut the drum.

Re: F1 brakes
The hub on the F-1 brakes has a different offset than the '53-56 F-100 brakes. The 53-56 brakes are the ones to use.

Re: F1 brakes
The backing plate itself is the same 48 to 56. The hub is different (and drum) 48 to 52 and 53 to 56
57 and up backing plate is all together different. |

Re: F1 brakes
There are some later pickup drums that will work. Did you modify the wheel bearings to fit the spindles?

Re: F1 brakes
After reading your post again, sounds like you have 53 to 56 hubs and a 48 to 52 drum.
The 53 to 56 drums is almost flat, the real 48 to 52 drum has a offset and a narrow brake shoe surface. The late model drum you can use on 48 to 52 hubs is also flat but has a wide brake shoe surface about 2-1/2" . |

Re: F1 brakes
Is the backing plate seated completely on the register of the spindle.
How much is it missing by when it hits the backing plate? Is the inside bearing seated completely on the spindle? You use to have to grind a radius on the inner bearing when adapting the later hubs to early spindles but I think now there is a bearing available that's has the radius to fit without grinding |

dkd35, are you sure which hubs you have? There is a big difference between the F1 and F100. There is about 7/16 difference between them. Last edited by JSeery; 05-23-2019 at 07:46 AM. |

Re: F1 brakes
My hubs are new from speedway. I have checked hub is all the way in .2inch shoes 2 inch drum . The 12" bendix backing plate is the same size of the outer drum not letting the drum to go back the 1/2 inch. If the drum was bigger the backing plate lip would fit in the groove and work. So it looks like cutting the lip off or 1/2 of the outer drum?

Re: F1 brakes
You got F2 / lincoln type brakes. Not like the F1 brake swap from a junkyard
Were did you get the drums? Also sounds like you got the 40 ford style repop hubs |

The offset of your repop Ford hub and drum are not compatible with these backing plates. |

Re: F1 brakes
F1 brakes are 2x11, how did you manage to mount them on a 12 inch backing plate? OK, so are we talking about something like the Speedway Kit "12" Bendix style brakes for 37-48 Ford spindles" 910-65420? As best as I can tell this kit does not use any F1 or F100 parts and is made for the original 37-48 hubs.

Re: F1 brakes
...and unless Speedway has changed the inner bearing in it's kit recently; you still need to grind a radius for it to seat properly.

Re: F1 brakes
The F250/F2 backing plates are too shallow where they mount to the spindle. This pushes the plate into the drum. There is no simple solution to use them. People have cobbled together ways to use them with Buick drums. I would not ever run these designs. You can buy old or repo Lincoln plates. Some of the Lincoln’s also are shallow. The rears work fine on the front.
