Brake caliper code where?

Checked door and glove compartment and found a bunch of other codes.

The guy at the store told me to measure the cylinder diameter. Which I will do as last resort. Just wondering where else it could be before I do that. Yes, yes, it's coming off anyway...

BTW I like our car quest store - when I got the wrong part online they had the right moog foe only $5 more. They also have Warner manual hubs for the same as amazon.

Its one of the codes on the Glove box door.

Yes its important, my 3/4 ton 4X4 GMC for example had 4 possible brake systems, and there were others for 1/2 tone, one ton and 2WD versions of each..

Thanks Legend.

I was always told the diesel Suburbans had the 3/4 ton series brakes on them. Guess not.

Maybe brakes are considered part of "Operating Conveniences"
