What type of brake pad is better organic or sintered.?

Question

what is the easiest way to find out if you have steel disc or cast iron?

Answer 1

I personally do not know of any highway cars having anything but cast iron rotors. Cast iron resists warping better than steel. There is an expensive high temp. steel that would work fine. It's called H-13. I worked with it in industry and if annealed properly can stand 1950 C thermo-shock , at room temperature, 60 - 80 degrees F. You are required to wear a #8 welding lens to watch this however. I wish I knew your application. Here's my take on pads and rotors. If rotors need replacing you must ask for "on shore " American or Canadian produced material. The rotors from China aren't worth your time installing. Life expectancy 2-3 yrs. at best. They're too soft and rust quickly. Stick to cast iron. If you want cut out veins machined on the rotors be sure there no through drilled loles. They 're prone to cracking. Speaking of pads, Toyota must know something. Their pads are organic and I've personally heard in conversations that they last 50 - 80,000 miles. There is enough stock on a Toyota rotor to re-machine them 2 times. All American car rotors are for the most part "throw - aways". I've installed many EBC Green Stuff pads and they stop faster than most ceramic or sintered pads. Rotors used with these pads last forever. But your lucky to get 30 - 35,000 miles on them these pads and they aren't cheap unless you buy them on line and compare prices. If you'd like to go with cintered pads I've had good luck with many Wagner Quiet Stop pads.

Answer 2

My mecanic informed me about ceramic brakes, so I've switched to those. Since I don't do my own brakes, my answer to the "easiest" part would be to ask your mechanic when you get your breaks serviced.

I've been really happy with the ceramic brakes he installed. They were a bit more expensive, but they've really lasted me a long time, so I feel that in the long run, I'm saving money.
