What dimensions or features identify the
precise sierra caliper model?

I have a pair of calipers of unknown origin
in the process of refurb, so any info. at this stage would be helpful.

Trueblue

basically there are 4 types, but one of those is the 4 pot cosworth one so I presume you don't have that one, and another is the big single piston one used on the 4x4 cosworth, again unusual if you have this one.

Which then leaves two, the ones found on 4x4 and/or abs-eqipped ones and the std non-abs 2wd ones. tricky to explain the difference between these. They have different offsets, and the 4x4/abs one is a bigger caliper with a smaller offset.

The ones you have came from a base model sierra,i think it was an 1800 cvh and i'm pretty sure it was a G reg.
