Monobloc vs. 2 piece calipers? I need info

[ducatiz]

Billet Moto-mono blocks (like the first photo) have all the passages inside, which takes a lot of fiddly, time consuming machine work. Time = money.

I think all the time/money is in the finish.

the internal passages are bored from the inboard side and then plugged.

Isn't there a further differentiation, as in forged monobloc? Or is the term forged to be used interchangeably with billet? Which is the mostest- billet or forged?

The 696 has Radial 2-piece calipers

...which are pretty damned good anyways

On the SS Turbo, the external crossover is a hard line that runs underneath the caliper (when looking through the wheel). I believe the Wilwood 4-piston caliper used on the latest HMMWV has a similar crossover line. A lot of performance cars these days run Brembo calipers, it's pretty common to see nowadays. The Cobalt is built on the Delta I platform, while the Cavalier was J-Body. Delta II is now used for the Cruze and Volt (which replaced the Cobalt).

I looked at the Ducati parts manual and see the bolts for the 696 calipers on the inside (inboard side of each caliper) even though they are radial mount, so it is indeed a 2 piece.

Mounting style and caliper construction aren't related. There were monoblock axial calipers too. Monoblock just describes the construction of the caliper while radial/axial describes how it's mounted.

All metal starts out as cast into a billet (square) or a round (ball)

Forging is the process of making a rough shape out of softened billet or round.  It is heated until soft enough to be malleable.  The most common process is Hammer Forging where the shape is literally stamped.  After being forged, the part is then finished using a cutter or CNC. The process of hammering while the metal is soft changes the grain structure and relieves internal stress.

Aluminum and steel can both be hammer forged, but it's less common to see it.  Forging produces a super high strength part because it aligns metal grains and stuff like that.

The monobloc are CNC cut from an aluminum billet and finished.  The process has several cutting steps.

I don't know of any hammer forged parts on the bike except for the crank and maybe the rods.

forged rims too

forged rims too

Forged on some, yes.  Not hammer forged though.
