Some but not all light duty and HD stuff swaps. If it has the vented "wide" rotor it's the same, if it has the narrow non-vented rotor, different caliper.
On the note of calipers:
YWST: Brand New Japanese OE Loaded Brake Calipers for 4x/5x/6x/7x Models
Yeah, We Stock That! We are very excited to introduce our loaded brake calipers. These brand new pairs feature 100% Japanese components from 3 different OE Toyota parts manufacturers. It took nearly a year to line up production and transport but they are now in stock! Applications include all...forum.ih8mud.com
Speaking of 7x series in general, some inner axle shafts can be the same, not always. For example 9.5" axles (which were never on light duty stuff) have a wider diffs and shorter short shafts than an 8" setup. Steering/Suspension stuff is beefier on the HD. While you're right the Prado 7x holistically shares more parts with the HD 7x, it's overall robustness of parts is better compared to the Hilux, Surf, PU, etc as the diffs, steering, brakes, engine, trans are the factors imo more so than the actual overlap of part numbers.
I was just comparing 1990+ LJ7x to HZJ7x with those part numbers.
As far as robustness goes, I agree with you regarding the engine, suspension and non floating 8" rear axle (that said, the 1990+ LJ7x suspension and axle housings are UNIQUE and not from a Hilux). Most everything else I consider the same as the heavy duty model(s). For example, the transfer case is a heavy duty unit (same as in FJ62 I believe). The A343F is found in the FZJ80 and UZJ100. The R151F is found in the PZJ77 and newer HZJ7x. The steering box is actually the same housing between LJ7x and HZJ7x. Body is basically the same as the HZJ77 from the firewall back. Frame is the same strength (just has different suspension mounts). Heck, they share the same repair manual even (RM183E).
It's the LJ7x engines that Toyota really F'ed up. They never should have put a 2.4 into a 2200kg vehicle.
