Thanks for asking, this should answer all your questions about pad types. Any further info needed, let me knowI want my stock pads to wear out so bad so I can replace them lol. They squeak a lot! especially the one without the engine breaking system. I took them off to check um and they look brand new. So.. i guess i want to upgrade. I see they have them on amazon. Is there a difference between the two colors? red and bronze?
