Who make Toyota OEM brake pads, what part numbers/manufacturer part number

[100 TD]

I am chasing info on the stock brake pads (front and rear) for 16" wheeled 100 series/Lx470 to 2002, or to 2004 if they are the same(not sure if they changed)
I would like to know if they are made locally in the USA by someone and badged Toyota or are they imported from Japan like some oil filters or other parts made by DENSO.
Any info would be good, I would also like the manufacturers Name and part numbers if they are made by someone else, as well as the Toyota part numbers.
I am trying to find out the differences in the different ones available in various markets, similar to info we are currently finding out about oil filters in this thread by uHu

In this recent thread, it is said the OEM pads are possibly manufactured by Akebono. Also, the Toyota part number for brake pads did change in either '02 or '03 for US 100's as verified by C-Dan.

if you had the part # you can tell if they are sourced in the US, I forget what the # is, but my guess is they are japanese made

From what I've seen, all the LC stuff minus the oil filter is Japanese-made (this includes the air filters, cabin filters, brake pads, and other stuff I've bought). Parts guy at local dealer and CDan tell me the front pads are the same from 98-02, then changed in 03 (caliper also changed, IIRC). Rear pads are the same from 98-05, changed in '06. Recall that the 03 went to 18" wheels, so my guess is the front caliper/pad changes are to compensate for the heavier wheel.

Somebody referred to heavier wheels vs brakes in another thread earlier, so I had to comment:
1
Brakes have to be sized according to the weight of the truck. The weight of the wheels is not a factor more than the weight of anything else, except if spinning wheels at standstill. (You could make a calculation of the inertia as a factor of the weight-distribution in a rim/tire combo, valid at high rotational speeds, but for a practical vehicle scenario, it doesn't really count a shmitzkin)
2
18" wheels are not heavier than 16". The tire is lighter at the same size & construction/type. as there is less rubber and cord. The rim will have more air, and might have a bit more alloy, depending more on model/type/width than on 16 or 18 inches diameter.

Hijack over.

I agree with uhu that the weight of the larger wheel is not the reason for the change in calipers for the reasons he mentioned but the larger wheel may have allowed the engineers to get a larger set in when previously they were restricted by the 16" wheel. Are the calipers the same as the new Tundra and enlarged for the GVWR/GCWR (7200/16000 lbs) of the 5.7L Quad cab trucks?

Toyota equipped all models in the new-generation Tundra line with the segment’s most advanced standard braking systems. The four-wheel disc brake system uses large ventilated rotors front and rear: the front rotors measure 13.9 inches in diameter and 1.26-inches thick (largest in the class) with four-piston calipers. The rear discs measure 13.6 x 0.71-inch and use two-piston calipers. Front Swept Area (4x2/4x4): 74.1 square inches. Rear Swept Area (4x2/4x4): 56.9 square inches​

This is a picture of a 2007 Tundra front brake unit. Is this the same as a 2003+ 100 ?

100 OEM Rear pads 98-05 Toyota Part # 04466-60070. (List price 8/06 $71.78) I recommend Cdan but bought these locally.

Can we get some side-by-side pics of the pre-03 and the 03+ calipers and pads so we can look at the difference . It would also be nice to get a OEM vs Akebono pad comparison.
