As a starting point, the Scorpio caliper has 90mm spacing between the mounting ears and the offset to rotor center is 38mm.
The 2012 Focus rear caliper has 100mm spacing and 38mm offset. Be sad, cause one out of two is bad.

I think Audi/VW used the same basic rear caliper on a lot of applications, varying the e-brake cable configuration and bracket, depending on the rotor size. I still have the 120K-mile originals on my 2002 A4, so they work.merkurdriver wrote:There is a VW / Audi rear caliper that's really really close to the Scorpio caliper that I'm looking into.
The 2012 Focus I just pulled a rear caliper from has 100mm bolt spacing.timxr8 wrote:It's a 90mm bolt center and a 38mm rotor offset, like the Scorpio and the 12+ Focus and 13+ C-Max/Escape.
But doesn't the Beetle caliper have the bleeder in the wrong location? It seems to me that the only one that has the bleeder in the right location is the B5/5.5 Passat, no?merkurdriver wrote:1998-2010 Beetle rear calipers.
Ah, I see. The thought had crossed my mind of routing the cable under the arm, but I didn't know what surprises that might bring. Sounds like you're still in test mode on this one Mike?merkurdriver wrote:I was thinking to switch the LH caliper onto the RH side (and vice-versa) to put the bleeder "up" and then you could use the (longer) Scorpio parking brake cable instead of the Sierra Cosworth parking brake cable - the extra length might give the extra needed to come up under and attach the cable.

I realize rebuild kits are available, but I'd much prefer to use a more modern caliper which is readily available most anywhere and has a broad selection of pads to choose from.milehighXR wrote:I can, and have rebuilt the Scorpio rear calipers. I just need cores, and lead time to order the rebuild kits, as I have only one source for the correct kit. Napa, etc... can't get the correct rear caliper rebuild kit with all the required parts.
Yes... "test mode" as in a pile of parts in a boxDPDISXR4Ti wrote:Ah, I see. The thought had crossed my mind of routing the cable under the arm, but I didn't know what surprises that might bring.

Sounds interesting. Let me know how it works out. I hope to have something mocked up soon with the Jetta bracket and Passat caliper using the Sierra cable.merkurdriver wrote:I think the Scorpio cable on the XR will give the extra added length needed to run the cable under the arm
I should have split that sentence. The 38mm offset is what I meant for commonality between the brackets. The Focus and C-Max/Escape brackets are 100mm mount center as you said.DPDISXR4Ti wrote:The 2012 Focus I just pulled a rear caliper from has 100mm bolt spacing...timxr8 wrote:It's a 90mm bolt center and a 38mm rotor offset, like the Scorpio and the 12+ Focus and 13+ C-Max/Escape.
