Re: '63 Giulia brakes

[Tony Stevens <tony@domain.elided>]

To answer Steve S oF Seattle's query about Giulia 101 Sprint brakes: 

The Giulia 101 Sprint was initially supplied with the triple shoe front
brakes. Disc front brakes were later offered as a no-cost option but
there is no firm evidence regarding dates or chassis numbers to confirm
when this was available. A '63 car probably came with an all drum set-
up. 

The triple show brakes were considered by the Alfa Romeo factory to be
superior to the disc setup, the eventual change was more of a cost
reduction & PR  exercise rather than a performance modification
exercise.

The rear brakes of front drum braked cars had steel rear brake shoes
with 1.752 wide linings, carried on from the Giulietta. Cars with front
discs had aluminium rear shoes with  2.252 wide linings together with
wider drums, different backplates, cylinders & return springs.

There were also changes in brake master cylinders, all drum cars had a
1.0" diameter cylinder, disc braked cars had a 0.75" diameter unit.

The rear brakes & master cylinder of the car in question may indicate
the original fitment by the factory, although a previous owner may have
carried out a complete front & rear conversion

There was never a production Giulia 101 Sprint Veloce, although owners
could convert to a "Veloce" type spec by using Spider Veloce or SS
parts. 

To further complicate the story, a customer of mine has owned from new a
very late Giulia 1300 Sprint of about '65 or '66 which was originally
equipped with Dunlop front disc brakes & master cylinder from the 105
series!
