I have 28A with rod brakes, I have a full set of 40’s backing plates, brakes & drums. I have a pair of 1940’s spindles. I also have a pair of F1 spindles, hubs & the lot. Can I use F1hubs on 1940 spindles & 1940 backing plates etc
The 1940 backing plates are for 12” brakes, the F1 are 11”, so no. You can adapt the F1 brakes to the 40 spindles.
To run the F-1 brakes, the inner wheel bearing should be chamfered to align the drum/shoe. Also you may need to grind some on the spindle for hose clearance
I don’t want to run F1 brakes, i want to run 1940 brakes, but I wondered if the F1 hub would work with 1940 spindles & 1940 backing plates (just hub from f1)
To try and clarify, I want to run all 1940, spindles, 1940 backing plate and 12” drums But I wondered if the F1 hub would work with this setup. The F1 hub seems to use same bearings & it’s five on 5 1/2 stud. It seems like it would work but I may be missing something? Is the F1 hub the same as aftermarket 1940 hub? (One Not swaged to drum)
the short answer is no you cannot the f1 inner spindle girth is fatter the f1 hubs offset id really close to the 1940 BUT it is not the same the trick is... IF you are using bolt on steering arms.... you fit the f1 spindle complete with its king pin and run f1 wheels. the f1 and the 40 share the same king pin incline the f100 is a very similar looking set up, BUT the hub is shallower and the kpi greater, to coincide with the smaller wheel diameter. if i may i would like to poin out the benefits of 'simply' bolting in the f1 spindle 1. the king pin is the same, and a smidge longer 2. its longer so there is more meat about the top of the spindle. 3. the inner bearing is bigger 4. the inner spindle girth is MUCH fatter - -they share the 3/4'' id outer bearing 5. the f1 brakes have twin piston wheel cylinders 6. the f1 wheel cylinders push the shoes into the drums at 10 and 2 o'clock - not like the 40 at 12 o'clock. 7. you can simply add seld adjusting cables and ratchets to them , its not that 'you' need no more adjust the brakes, its that they are constantly at the drum.... 8. the front drums being 11 by 2 are the el cheapo rear drums from a 60's bronco and cheap and readilly available. 9. they are 5.5'' pcd 10. if you are running an 8 or 9 inch rear with small bearings, when you find some 10 by 1.3/4 rear brakes, you can almost mimic the f1's 11 by 1.75 rears and have the almost factory front rear 75 percent of the front at the rear, which is nice. to clarify, you cut the f1 steering arms off and wang the whole lot on. if the king pins are stuck, heat everything up and pump grease through and it will boil all the hardened stuff inside out. if running a 4'' dropped axle fit the 1 and a bit steering arms if running a bone fit the 3 and a bit drop steering arms i think the last iteration of front drum brakes is 1968 this you acheive by adding the self adjusters to f1 f1 and f100 use the same back plates f100 ends 1956
Thanks Nobby, plenty to think about here. I would prefer to keep it 1940 brakes & stock rear axle. I’m running stock 4 banger (but might get bored with that) I have narrow 8” rear axle & all new brakes (might not need it), I also have F1 spindles, hubs & brakes certainly have plenty options. It’s running stock right now. Thanks for info
