Quoted from PinballAir:Did an oil change yesterday and rotated tires.
I also found a screw in the tire and plugged it.
The left front pad brake material had separated from the steel backer at 55K.
Does anyone remember when the guy at the parts counter knew what he was selling?
I go to NAPA because I think the quality of parts are better there than the discount stores.
I wanted ceramic brake pads.
The counter guy said I think these are ceramic.
I bought NAPA ultra premium pads and there was no info on what material they were made of. AND , as ultra premiums, they matched OEM performance. Hmmm, match the factory pads as Ultra Premium.
By law, there is an edge code on new brake friction. Google the number for details. The FMSI (Friction Maanufacturers Standards Institute) code will tell you the size, shape, back plate size but not the actual friction. The edge code will tell you everything.
Note that thanks to the nutjobs in California and Washington, All brake friction has to have less than 5% copper with pads and drum friction (Think the majority of class 7 & 8 trucks) made after December 31, 2021. After December 31, 2025, they must contain "zero" Copper which means under .5%
With this, you will notice different performance and durability characteristics of brakes. It will also affect rotor and drum wear.
