I have 15k miles on my brake pads and rotors and 20k miles since I had the brake fluid replaced. I am running Axis pads with OEM rotors. The car does not feel right breaking. It seems like it takes more distance than usual to get the car to stop.

Is there a way I can check the brakes myself to see if they are in spec?
I tried searching the forum for some help on how to go about checking but I couldn’t find anything. Thank you for your help.
