How about a rough exploded view. All these washers are necessary.
Here is the rear view. Again I if I had had more time they would be better shots. You can still see the MX-900 and the date code. The small piece of inner tube is a trick that I learned back in the day. It gives a nice tacking spot against the fork and it also protects the finish.
It got a new home. I have always loved these brakes and thought why not. That is an MX-900 and that is a 2.125 tire by the way.
Oh yeah this brake came off the bay for 11.00. My preference for cleaning is a soft toothbrush and some type of liquid penetrating oil.
