OK, I got curious & did some checking. Metric calipers are mid '80 GM S10 or Regal, Malibu etc. parts. Advance has 'em for $10 ea.+ $10 core but you can toss some old calipers in the boxes & get your core back. The hardware is included according to the website.
Brake pads are as cheap as $10 if you shop around. Inner & outer bearing sets with seals will set you back $20 for cheapies or about $35 for Timken or National if you are like me & want the best. The caliper adapters run from $30 a set shipped, $38 a set(Jegs) to $50 or more. Brake hoses are $10 ea.
This is my dry run at a setup from Advance. GM calipers, hoses & pads plus the cheap bearings & seals for the rotors using discount code BIG30 & after taking some junk calipers in as cores will come to just under $50 tax included. You will have to pick this stuff up at your local Advance to save shipping but mine shows it all in stock. You still have to order & pay online though to get the discounts.
The grand total:
Rotors, calipers, pads, hoses, bearings, seals & caliper brackets is $160 if you shop carefully & use discount codes at Advance. You will need to get banjo bolts if they dont come with the calipers & brake hose clips if they don't come with the hoses but thats it. 11" brakes 5 on 4 1/2" Ford pattern cheap.
