Following my car service a few days ago, I have enlisted the help of my friend Tim to change the brake pads on both the front and rear:
On this front right wheel, we can see the rotor and the brake pad:
I was suggested by the dealership mechanic that the rotors might need machining. Upon a closer look today, however, there seems no to be such need. I also feel vibration when applying the brakes, so the suggestion was probably more on the cautionous side.
After taking it apart, I quickly snap a couple of photos.
In both pictures, the left one is the used one, and the right one is the new one. Needless to say, there is a huge difference on how much the brake pads have been used up. An hour later, the brakes are working fine with stronger stopper power.
