Dare G4 Brake Caliper

[jpf]

My 2003 Dare G4 long body (8,000 miles--largely pleasant) has had the right rear caliper seize and needs to be replaced.
Does anyone know how I go about finding a replacement caliper? What the part is from, etc.?
I will call Dare tomorrow, but thought those in the know could offer insight.
I'm in the USA.
Dandarez are you out there?

Thanks for the advice!

My mechanic traced the caliper to a Merkur which is the American version of Sierra Cosworth.

Again, thanks a bunch. I am hoping to drive it a bit more before it is retired for the Midwestern winter!
