BMW and MINI – Cool Carbon Brake Pad Replacement – Low Dust, Long Life
This answer is applicable for many BMWs in addition to the one listed below.
car year: 2008
car model: 328i Sedan
I have a 328i Sedan with 27,000 miles on it. It’s still in warranty, but I was considering replacing the stock pads with Cool Carbon pads now. Could I use the Cool Carbons with the existing factory rotors? The factory pads produce a lot of dust and I’d like the wheels to stay cleaner longer, plus I’d like to get longer life out of the rotors. What would be your recommendation?
We do typically recommend that fresh brake rotors be installed when installing a new and completely different brake pad set. This is to assure proper and full performance of the new pad set. However, if the current rotors are true (no warpage) and smooth (no grooving or discolored areas), do not have significant lips at the inner or outer limits of the wear area and (finally) are well within the minimum wear thickness specs you can likely install the new pads with a minimum of any potential negative side effects (pad and/or rotor scoring, possible noise). Of course, if you want to assure the best operation of new brake pads, installation of new rotors would be the first recommendation.
With the above points made, we certainly do recommend (and use, ourselves) the Cool Carbon brake pads. As you had noted, they produce less dust than the BMW original pads in addition to providing a more progressive pedal feel, long life and excellent rotor wear.
Don’t forget to replace the pad wear sensor wires. Even if the warning light has not come on, we have found that the original sensor wire often breaks when removing it from the pads and, therefore, cannot be installed on the new pads.
