Re: [Amc-list] Cheap brake conversion

" Availability is certainly a good feature, and as entertaining as I find 
" developing these conversions is, I wonder how practical or necessary it 
" is.  Don't misunderstand me, I designed a rear disc brake conversion for 
" my 1968 AMX in 1974, and I converted to the 1971 vented brakes before that.
" But honestly I don't think that I at least will be needing to replace 
" brake parts on any of my hobby cars. I remember the 1974 Ambassador 
" brakes lasting about 40,000 miles and the rotors didn't need to be 
" turned, but if I did a brake job now I would turn the rotors.  Don't you 
" think that the rotors could be turned twice?  That means the rotors 
" would last 120,000 miles.

one thing has changed, for newer brakes at least and maybe for all
replacement parts: rotors are made of softer iron than previously,
because customers are so picky about brake squeal.  the soft iron
doesn't squeal, but it doesn't last as long either.

i have a possible availability upgrade for the '74-8 bendix spindle
with the big bearings, a mopar part.

yes, it's from the '70s/'80s, but look at the coverage!  it has the
same 5x4.5" bolt pattern, the same #17/#16 bearing sets, the same dust
seal, and afaict a similar rotor 'hat' as the amc big bendix.  the one
difference: it's ~1" larger, so a new caliper bracket is called for
and 14" wheels are out - but many of us, especially performance types,
have or want 15" or larger wheels anyway.

partsamerica price: $30.  they also have 4 other wearever and
raybestos rotors, with prices up to $97.  the raybestos claims to fit
mopars back to '69...

partsamerica '74-8 matador rotors: bendix $47, raybestos $135.
