John - The changeover to three platform brakes happened Jan 1959. Wheel cyls, support and backing plates, etc. Nothing changed from 57 thru early 59. Spindles ? Not sure how long they used the same ones. Parts book would have the answer.

I believe stock brakes 59- 62 interchange ,62 last year of the two leading shoes , says spindles probably do too . In fact spindles may carry later into 60's ..., if the later 63 up Bendix style drums Bolt on to similar spindle interface ) --But That is not the issue here... I know 60 parts fits late 58 /59 too, ? may fit 57 if used With 57 / early 58 upper control arms ( has smaller upper frame bushings) . I used 59 de Soto Lwb frame under a 57 , used 60 F brakes / front end parts on that frame as I had them . Late 58 up brakes way better structurally than 57 , upgraded mid 58 . Why wheel cylinders differ . Looking at ? larger front discs than current upgrade tech allows -limited due to our small wheels ( 15,14) . I read in an SAE article that 16 " wheels are the best engineering trade looking ahead on tire roadworthyness ,handling etc. - same rolling OD, with smaller sidewall . So tires available in 16" will be many . coincidentally I converted a few to that size over getting really good top end Michelin tires . In the future I think tire companies will look at 14 and 15 the way our generation looks at 6" model A tires on wire wheels . Would love really good brakes , - you do not have to worry about, like a modern Jeep GC or corvette . Fit in 16... ?? Just looking at this right now .... Brake guy I am working with had worked on 62 300 ( and up ) ok , but not before then . He has all 62 data , I think the same spindle goes back to at least 1960 . FYI , - John ....
