    Squeaky Brake, brake dust or...?

    After my first service at 5000 km, my 987s' brake seems to squeak a bit occasionally. I notice it especially with the top down and it is an occasional high pitch squeak when the brake is applied slightly, should I be concerned? Is there any reason why? Brake Dust?

    Maybe I should take it in to have it check but just wanna check with the other renn teammates first. My first service showed that my front and back brake pads were 90% to 85% in tact.

    Re: Squeaky Brake, brake dust or...?

    May be a bit of grit or a small stone trapped in the calipers. Look to see if there is any scoring on the disc. Sometimes reversing as quick as it is safe to might dislodge it.

    My brakes squeal slightly whe only applied gently - its good ractice to keep the cross drilled holes clean - running a 5mm drill bit through them (by hand) every 6 months is good practice

    Re: Squeaky Brake, brake dust or...?

    "(by hand)" haha I can just see someone drilling the heck out of their rotors. Good thing you put that in there.

    Alright I should call up the dealer to double check but thanks for the advices. Indeed, this is the case, when I apply the brakes slightly, it will squeal like touching the brake paddle. However, whenever I brake with force, the squeal is not there. My father's Jaguar also seemed to squeal with this pitch and he said it was due to the brake dust. Well, maybe it was there all along but I never noticed it because I kept my top closed due to the scorching heat in HK and I could never notice. Now fall comes and I tend to drive with the top down daily for an hour or so and the squealing is becoming apparent and especially when going into a tunnel. Maybe I should give it a thorough wash and see how things go but nonetheless, I don't think that it is normal to squeal anyway. Let me call them up tomorrow and check.

    It is normal. The more performance oriented the brake pad, the more they squeal.

    If the squealing is worse than it normally sounds and the pad thickness is fine, a pebble may be caught and reversing the car and then using the brakes to stop should get rid of the pebble.
