Comments about Wagner Disc Brake Pad:

Easy to install, but bedding was necessary. No problem. Brake feel was poor / decreased over the OEM (MINI Cooper) Brakes. Brake feel was better after bedding, but still sub par. I'll be doing a pad slap in the spring w/ an upgrade.

  • Q:

    Do these come with the wear sensors? (2005 Mini Cooper)

      The wear sensors are sold seperately.

      No they don't, but I reused mine. They come right out - pull straight up & the metal clip can be reseated on the sensor. Make sure you clean them w/ a little brake cleaner & be careful not to pull too hard on the wires. Mine only had a sensor on the Drivers side, which is funny... because my PASS side was squeaking... Why i changed them in the first place.
