Default '87 caliper pressure

Anyone know what the pressure is supposed to be at the front and rear calipers? Got an '87 showing 1000psi at the front and one rear and a leak down on the other rear to 500psi.
Thanks,

I remember, years ago, looking thru an EARL's SUPPLY catolog/listing, and they had some military/aerospace surplus guages for sale. I noticed some hydraulic high pressure guages, with small NPT fittings, that were rated 1,000 up to 5,000 psi measurements. I assume some could be used to measure higher pressure in automotive brake systems?

Waekon makes the kit for testing ABS pressures...

....the only problem with this is that it does nothing for measuring pressure at the calipers up or downwind of the abs....
