so i jus recently got some dtm kreuz 10 in 19's, the 3 piece design. they are light weight and i really dont feel a difference in power or anything while driving, but i feel like my braking has gotten shittay. kinda. sometimes i feel like the brakes jus want to fail. its weird. and when i stop kinda hard it makes a "louder" sound, its hard to describe. anyways, i have about 14k miles on my car, when do brake pads need to be changed? and do you guys recc. any good ones, low dust and hard stopping? thanks.
