Do I need new brakes??
Hello All!
Trying to make an educated decision here. 5000 miles ago I switched from oem brakes to EBC red stuff pads to reduce brake dust. At the time, my co-worker mechanic told me that he could resurface slotted rotors (yes I know, sigh) so he did. Car was braking just fine, no issues until recently. Bad vibration coming from high speeds when braking. We check out the rotors and the front 2 rotors are heavily warped. I’m not sure if I ruined them when I got the rotors resurfaced. Anyways, I got 2 new rotors but according to every forum I’ve read, it is highly suggested to also replace the pads. Given that they only have 5,000 miles, if that, I’m relunctant to replace them. What are the odds that my brakes are also compromised? Should I even risk it or just shell out and get new pads? |

You have experienced the issue my local BMW Master Tech told me about. He advised me once it comes time to replace the brakes just go ahead and bite the bullet and install new rotors. Don’t resurface because it will warp, and with time old rotors most likely also warp. The reason he gave me was the design of the rotors itself was thin enough to reduce max weight without sacrificing stoppping power. The downside of that is a pricier break pads replacement.
And to answer your question, Yes…. I would install new pads as well. |

You most likely did not warp your rotors. The red stuff is a lower performance brake pad than oem. You most likely exceeded the limits of the pad. Not to tthe point of brake fade but to you are just under it and then brought the car to a stop with the brakes still applied (i.e., spirited driving then stopping at a red light). This causes uneven pad buildup on the rotor surface which gives the pulsing, vibrating feeling when applying the brakes.
You can either replace the affected rotors or clean them to remove the pad deposits. I would look at higher performance pads. If you are still wanting to stay with EBC, the yellows will handle harder breaking and will dust less than OEM. Now you do have to be aware they will dust a bit more than the red but the dust is grey. |

To answer your question, definitely replace the pads along w/the rotors - cheap insurance.
On the rotors, the amount of mass of these rotors is significant and you feel the pad transfer in the form of vibration and NVH. I also assume you are referring to all 4 rotors vs only the front? |
