High Pitched Brake Squealing on 987s
They recommended that to reduce the high pitched squealing, the only way was to change the pads (no way my car was never tracked and only had 6000 km on it after 9 months and I don't think pads are needed until 30K or so).
The good news is that technician checked the brake disc and assured me that the disc was fine (it wasn't warped or anything). Advisor mentioned that the uneven wearing out of the brake pads at times on high performance brakes would cause vibration noises and he said it was a FEATURE/CHARACTERISTIC of Porsche/high performance vehicles. The degree depends on individual driving habits and cars (living on twisty hilly roads would cause the brake to squeal more going downhill). He cited examples of BUSES when braking (that part was right cos oftentimes, you would hear similar squealing when buses stopped) and he said it would be more evident in a boxster cos of the soft top. He asked me to listen carefully with the window rolled down driving and he said it would become apparent that even most normal vehicles would produce those noises. Well,
regardless of the explanation, I think I am through with this. To have them further look into this case would cause not only my time but also my patience. I did however regret taking it in because the characteristic they mentioned did not go away ultimately and they ended up SHAVING away the sides of the brake pads so my rear pads have uneven contact with the disc. Hence, I can distinctly see the disc top side and bottom side retaining a strip of rust even with hard braking because of the uneven pads (imagine, top and bottom sides shaved away leaving only the middle). My advisor however reassured me that with times, the pads would wear itself down naturally and become even again and the rust would go away.
Any input and comments? Was it a mistake for me to go through so much hassle to get this looked at?
