Re: IML: Budd rotors

["Bill Watson" <wwatson5@xxxxxxxxx>]

It may be true that 100% of 1967 Imperials had the Budd disk brakes, but
that 100% totals 17,614 cars.  As can be seen below, "very few" is a
relative term.

For the 1967 model year, 218,716 Chryslers were built, and of that only 6.2%
had Budd brakes.  Which works out to 13,560 vehicles.

Imperial built 15,362 cars for the 1968 model year, all with Budd brakes.

For Chrysler production :
1966 : 264,848 - 1.8% - 4,767
1967 : 218,716 - 6.2% - 13,560.
1968 : 264,863 - 8.4% - 22,248
Total - 40,576

For Plymouth -  :
1966 Fury : 331,926 - 0.7% - 2,323
1967 Fury : 358,685 - 3.4% - 12,195
1968 Fury : 430,357 - 4.1% - 17,645
Total - 32,163

1966 Polara/Monaco : 168,445 - 1.8% - 3.032
1967 Polara/Monaco - 123,648 - 4.4% - 5,441
1968 Polara/Monaco - 182,026 - 5.1% - 9,283
Total - 17,756

So, as you can see, if you can get the Imperial Budd brake discs to
interchange with the rest, you can quadruple your potential market.  It also
shows how weak Dodge was in the marge car market in those days.

The 1966 Canadian parts catalogue shows the disc brake with a separate disc
and hub, with the notation that both are serviced in 5-05-3.   That section
lists the disc and hub as one unit.  But the illustration shows the lug
bolts are installed in the hub while the hub is attached to the disc.   The
disc had five holes and there is a bolt shown in position to go through the
disc and into the hub.  Judging by the bolt illustrated, it is a normal bolt
that just bolts into back of the hub.  It does not appear to be a stud with
the wider base needed to press fit the drum and hub together.

The front studs holding the wheel in place are listed in section 22-05-14,
but those bolts at the back of the disc do not have any type code.

So, just how does the Imperial disc differ from the rest?  We know the hub
does.

There are more disc brake C-bodies out there than you think, especially 67
and 68 Chrysler models.  Seems like another one is popping up every week.
As with our Imperials, the c-body guys are hosed when it comes to replacing
those rotors.

AFAIK the Budds first appeared as optional equipment on 1965 Dodge and
Plymouth police vehicles.  Both the 1965 and 1966 MPC show the Budd rotor
and hub to be sold as an assembly, p/n 2534144-5 for right and left.  Does
anyone have a later MPC showing the rotor being sold separately?

It would sure be great if the only difference between the Imperial rotor and
the c-body rotor was the way that the disc was drilled for hub mounting.  I
don't suppose it's possible <gasp> that the Imp and c-body rotors are the
same?  In looking at my pics of the Budds on a 10k mile 69 LeBaron I can't
determine how the hub and rotor are joined -- 5 bolts from the back
(knuckle) side???

I'd consider adding Budds to my 65 Polara vert and/or 66 Fury vert if I knew
I could get rotors.  And if the rotor price was reasonable.
