The price and safe of the disc brake pad depends on what ?

Disc Brake pads include steel backplate with friction material bound to the surface of disc brake rotor.

1, Do you know, what is thickness of the steel backplate for brake pads? I think no too more poeple pay attention to it, nobody asks it at all, in fact according to the OEM standard, the brake pads for most of cars, the steel backplate is 5 mm thickness, and 8mm for truck brake pads.

Maybe you ask, why you saying this, who cares of it? at least no any customer never measure it at all, and nobody can know it by eyes only without a measurement tool. even the wholesalers, distribution, importers don't pay attention to it. it seems all of poeple always care for the price. Yes, this is market economy, there have a lots of competitions, the salers strongly need cheaper competitive prices. therefor, some manufacturers try to find ways to reduce any possible cost. we know, the workers salary, materials cost, warehouses, plants, machines etc are no possible to reduce, but finally they find 4 mm thickness backplate is a good choice to reduce the price, 1 mm is 20%, that is say the backplate reduce 1 mm, the unit weight will be reduced 20%, the backplate cost will be reduced 20%+, the important is that nobody pay attention it.

Even some manufacturers use the USED backplate from the waste brake pads.

I don't know what are the consequences, just by now I did not hear any traffic accident was caused by the Brake pads backplate thickness, even so, I still worry about it, Theoretically, the thin backplate is easy to deform, when we make the braking, high temperature, the brake caliper's pressure and frict with the brake rotor... anyhow I still worry about the safe matter.

2, The friction material, for a good brake pad, we need a good formula, in order to get a good performance, no noise, no dust, non-pollution. the material approximately include, Steel Fibre, Sponge Iron Powder, Kevlar, Vermiculite, Phenolic Resin, Nitrile Rubber Powder, MBTS, Graphite, Ceramic and so on, they are not easy to reduce the brake pads price base on keeping the good performance.

Hope all poeple no use the thin, waste, or any disabled disc Brake pads.
