The real question who in the hell ****ing cares??

I didn't, until I found the brake pads fitted by a quick nationwide chain a year earlier were totally disintegrating.

Funny thing is you can get the same brake pads at a scrapyard for a fraction the price, but no-one wants to.

It's a valid question of who cares about choosing the proper brake pads.

Bear in mind that the Toyota FF pads are $157 a set at the local
dealership, while at a local parts store, I can get FF pads for $20 a set..

C = Up to 0.15u
E = 0.15u to 0.25u
E = 0.25u to 0.35u
F = 0.35u to 0.45u
G = 0.45u to 0.55u
H = 0.55u to 0.65u
Z = Unclassified

That's a huge difference in price, for material that has the same friction
coefficient, if not quality, don't you think?

That's retail. And really the difference is greater, I once bought a set of 4 brake shoes for £1, that's under $2. They performed without any issue. Why? No-one here wants to buy brake parts from scrapyards, even though they're the same parts you get in the shops.

In the end, I don't see any indication whatsoever that anyone here knows
how to properly compare the performance of those $157 and $20 brake pads
and shoes in order to make an intelligent buying decision.

if both do the job ok, $20 is the intelligent buying decision.

That's kind of a sad revelation for this newsgroup, don't you think?

No, it's an electronics newsgroup.

Moving to historic vehicles, how would I find out which friction rating oak is?
