I am not sure
that info in link is right, re : when it happened?not 59?? ?.our
experience is that this change happened in mid 58? On 300D, along with larger
control arm bushings , other stuff. Protecting torsion bars from snapping off.
Late 58-61 are the same; 57 early 58 the same . I do not know this as hard
cold facts , but we have had this issue ;58D can have either size, often
you get the wrong ones. Documentation of all this generally a wreck at auto
parts stores. This link says 59 was change ???? .or maybe only low production
hi perf like 300 got it in 58? . But upgrading to 60 stuff (or 61) with
the 60-61 backing plates you get a much better , more evolved setup. 59 MIGHT
be same. The big flat spring (easy to put that in wrong, too) is thicker ,
cams stay put, backing plate spacing front to back therefore thicker . Other
issue is that the large diameter 12? 60-61 backing plates described are rare
compared to those improved backing plates for dodge plymouth, lower power, or
short wheelbase Chryslers. Smaller diameter drums, different width shoes
too. Buyer beware ; I bought a whole set up, all wrong. I believe
shoes are different too, some have that little depressed area to hook return
spring, --I forget the exact issues.
Steering box
changes too?/When? Later ones , late 58/59 on up seem to be used for quite a
few years after, in many car lines ; anyone know?
I do agree a
lot of bad press on total contact brakes has come from well meaning people
mixing up all these pieces .
Power brake
masters vs non power are another quagmire..the pedal ratios are different, not
just the masters,-- master mounts,(that plate)_ firewall drillings and
pedal push rod location, vs MC bore height . Parts physically fit that do not
work in that area. The firewall differences are really surprising, car body
must have been designated power brakes or not from get go, sets pedal ratio. .
Which also sets pedal swing arm heights in upper dash and ratios on pedal arm
drillings(all this on 1960 Matador?same body as F) ..and adding to confusion
there are often two drillings on pedal arm , both wrong for manual brakes. At
least two pedal arms. Plus bores of cylinders.
Maybe others
more fanatic on the record keeping side can chime in.. Or maybe all this
exists somewhere..
Yes ----save
all OEM stuff off these cars?.
Why getting an
unmolested car matters, too.

Good thread w/pic?s about Chinese re-pop junk brake

Makes me think I should start saving the old OEM cyls for
cores.
