I think in my case its my ceramic brake pads heating up the rotors creating a grinding noise. Once the rotors cool down they work fine, but if I brake hard at a high speed the grinding noise returns and will continue until they cool down.
However, after finishing the front and putting the tires on, I drove around the block and the brakes were making a horrible grinding noise. The vehicle braked fine, but the noise sounded terrible. I read online about having to bed in new brakes, but I was wondering if there was another potential problem?
I once bought OEM ceramic pads for the P5 and after a few hundred miles they began grinding. Eventually, the rotors became badly scored and when I pulled the pads, I discovered they were not ceramic and were filled with chunks of scrap iron or steel.
If the noise came after doing brakes, it's probably bent in right next to the caliper bracket. Dust shield on rotor is a pretty obvious noise. A light metallic grinding, but with a kind of funny 'hollowness' to it that comes from the vibration of the thin metal shield.
Re: Ceramic brakes "grinding rubbing" noise just before stopping? My CC brakes started making a grinding sound at about 10k miles, but only at low speeds, just like yours. I first thought I might have worn the pads down through the (very unreliable) wear sensors.
A grinding noise on braking is usually caused by a lack of brake pad material; the pads and rotors are now metal to metal, with no braking material left. Brake pads are like bars of soap. Eventually they get used up, and you have to replace them and spend a little money.
I had new rear brake pads installed and that same noise you wrote about occurs for me. They've taken the brakes apart twice now, see nothing abnormal, no debris, etc. They said that they installed ceramic brake pads because they are quieter (really?? never had that sound ever before) and said the brakes needed to be broken in hard, as in ...
The rotors are worn – If you install new pads on worn rotors they will make a grinding noise because the new pads need a smooth surface to rub against or otherwise it will come to shortening the life of your brake pads. This is resolved with buying new rotors.
Brake noise is often a sign of brake problems, squealing, screeching brake pads, groaning or rattling brakes are an indication that your brakes need attention. How does brake noise happen? There are many faults that can cause brakes to become noisy; damage to the brake pads or lining, damage to the brake drum and damage to the springs can all ...
Only use Semi-Metalic pads or if you have a car that is 1955 and up, you can use ceramic pads, they are the best, no grinding/squeaking/grabbing or rubbing The new rotors should be turned to remove the film and the pads should be trued to the rotors.
Hey friends. Here's my situation. Changed all four rotors (purchased from iRotors on eBay with ceramic pads). They've been on for a few weeks now when I noticed a strong grabbing feel/grind sound when I apply the brakes, especially when I brake and turn.
12.) removed old brake pads/clips and installed new brake pads/clips 13.) compressed the caliper piston to it's initial position 14.) closed the caliper assembly and checked all torques on it (75 ft-lb for the assembly and 25 ft-lb for the bolt that keeps the assembly closed)
