The other day I started cleaning up the twin Brembo disc brake units before remounting them on the fork sliders. I removed the 4 hex nuts and wavy washers that bolt the Brembos' to the sliders and placed them in mineral spirits to soak. The next day I laid out the 4 hex nuts and found only 3 wavy washers :o. I did a good clean-up around my workbench but could not find the fourth washer.
I went to the micro Fiche files at MAX BMW to get a parts number for the wavy washers and found that wavy washers are not listed with the large hex nuts that hold the disc unit to the sliders??? Do any of you have any thoughts and or experience with this? Did they used to use the washers, do I need to now? I would appreciate any guidance. thanks D2

These are actually listed as Fillister head nuts, not Hex nuts ::) D2

Hey, Dave
I'm guessing if the washers were not shown on the fiche page, they probably weren't fitted OEM. However, thin washers can sometimes protect and help prevent scaring alloy bits as the steel nut/bolt is snugged down.
For local wavy washers in metric sizes, visit the hardware aisle in either Home Depot or Lowe's.

scaring alloy bits? you're spellcheck on the blink again bud?

Thanks Monte, I'll get to Home Depot in the next or two, I did not realize that I could get the washers there. That will help with the occasional missing hardware piece. I am a bit envious of your being able to ride with the temps in the 80's at this time of year. We are going to have a high somewhere in the 40's today with a light rain just to make it extra gloomy. But it makes it a perfect day to work on Greta. 8-) D2
