Nonsense. Yes replace discs in pairs, pads in pairs, shockies in pairs, but having a new and old caliper on axle is fine as long as they both work equally.
The pedal pressure and caliper action is still the same,
you dont get sudden caliper failure, and if old one was that bad you would feel it.
I fully approve of best practice, but in this instance no,
off course, his old caliper will surely need looked at long before the new one... but that is fine.

Calipers don't burst, seals leak but don't give way,
off much greater importance is regular fluid changes and regular inspections of flexible brake lines, these will fail dramatically without warning.

And well done to Moveitall for having his repaired brakes checked on rolling road btw, good practice.
should have mentioned that.

thats the key as long as they both work equally ,often you end up with an unbalanced pair,if only one is giving attention

Fair comments - I prefer to urge on the side of caution...

And yes, good show getting a Rolling Road test done...

Maybe 'nonsense' a bit harsh, if money not an issue, heck, motor factors need to earn a crust too and they will gladly sell you re-con calipers,
which are simply... stripped, bead blasted, new seal, new cover, new nipple,
new piston,,,, bench pressure tested. Pretty coat of paint.

Strip and do seals etc yourself, same result. But more money for pub

ive reconditioned hundreds of calipers ,but the amout of vehicles you see with 1 new or rebuilt caliper and half seized on the other side is worrying

Yip, i agree, but there are millions of perfectly servicable calipers scrapped or exchanged each year, and if your unsure, buy a pair.

Its pretty simple stuff to refurb at home as long as you give a good pressure teat and do rolling road, i don't do rolling road, i take it for a road test and gradually do ever increasing speeds and agressive braking, feel the pedal, return home and check for leaks, including pulling dust boot back to see if seal is holding up, something else will ususlly fail before caliper.
