hi i think the older tundra's 2000 2001, had issue's. i bet those guy's have the answer your looking for.
i know my 05 stop's great w/drum's in the rear.
i wonder if the older tundra's also has a different master cylinder in any way. smaller less fluid, etc.

i wonder if you could fit a 05 or 06 front rotor & caliper on the older tundra's.
if yes, i bet you might be able to get a used set from a salvage yard.

or a trd kit, brembo, etc -but that to is very expensive.
as far as the rear conversion kit,
i don't think since you have front braking issue's putting a rear disc conversion kit will solve you problem.

i wonder if you post in the braking section here might help.

where are all these old member's that were ase toyota mechanic's when you need them.
when i 1st came on , there were several member's that always helped.
1 guy used to say NO CHARGE!
i thought that was funny.

on a serious note, i truely hope you get this resolved,
gorilla
