Centric brake calipers

Looking for info on the difference between the Centric 141 and Centric 142 calipers. The 142 is listed as zinc plated and "premium." is there any difference between the two in actuality. I am looking for technical, specific information. Thanks for any help-

142 is also a "loaded" caliper, meaning it includes pads

ok, got that, thx. Makes sense. Any other difference, in quality?

the difference is the 142 are zinc plated.

the zinc plating is great. worth it IMO.

Ok- I finally called Centric and talked to their tech dept. Guy said model 142 Caliper is yes, zinc plated. It also uses all BRAND NEW pins, piston, boots, etc. The 141 may reuse these parts if they are serviceable from the original cores. Both models use rebuilt cores. But only the 142 uses ONLY the cores. End of story. Seem slike the 142 is worth the extra few bux.
