I replaced my buttons five years ago and when I took the wheel off yesterday the disks where a little too loose.

I search but could not find the article on what tools you need to replace the buttons and how best to do it.

Can someone point me to the article to replace the buttons.

No special tools required - try doing a search for bobbins.

One front disc was repaired in just over an hour, using the following method, which
assumes that the rider has some mechanical aptitude (usual disclaimers apply): -
1) Jack under the sump, to allow the wheel to rotate.
2) Assemble: - copper grease, lead lamp, short luggage bungee, small hammer,
8" terminal screwdriver, 8" x 1/4" screwdriver, rag, solvent, beer, beer crate & cushion.
3) Using bungee through the wheel, hang the lead lamp to illuminate the inside of the disc.
4) Place cushion on crate, put crate in front of wheel & sit on cushion.
5) Using terminal driver as a drift, with hammer, tap the first circlip off.
6) Remove all 3 bits & keep separate from new ones.
7) Lightly grease bobbin, inside of disc where the washer will go & the ends
of the circlip.
Fit the bobbin & the washer (check instructions for correct orientation), ensuring that the washer & bobbin are concentric, then push the terminal driver into the circlip slot to hold the washer in position.
9) If you have aligned correctly in step 8, then the circlip will slide into full location, just by pushing the back of the circlip with the 1/4" screwdriver or at most lightly tapping the clip firmly home. If the clip doesn't go into the slot, try compressing the washer with the screwdriver whilst pushing circlip with a finger.
10) Ensure clip has fully seated, repeat 11 more times. Wiping the disc with a solvent soaked rag as you rotate the wheel, to remove any grease, which may have gone astray before it gets onto the pads.
11) Drink beer.


Notes
Do the other side.
I found the brakes were crap after doing this, but they soon bedded in to their new position.
One can remove the whole disc from the wheel, but the bolts are well glued & have been known to strip the ally thread in the wheel.

You could do all that. I just grabbed a couple screwdrivers, pliers and a pick tool. Popped the old ones off and the new ones on. Pulled the wheel around by hand when I needed to move it.

If you're using OEM bobbins, there are three on each disk that have a little spring wire inside - don't put those back in the same hole - move to the next hole one way or the other. If you're using Motobins bobbins, you don't have to be concerned with any of that.

I didn't grease anything - seems like grease would tend to trap fine grit in there and cause premature wear.

But Jim, you left out the "beer, beer crate and cushion". Those are the most important items, without them, it's not a proper job!

The only problem I had with the beer, crate and cusion as recommended back in the summer when I did this job on my brick was,,, I started the job in a Friday evening and woke up on the garage floor on the Saturday morning!!. Replacing the bobbins is easy, but watch the strength of the beer. .

Cheers.

After I posted this question I went to the local Bmw guy here in Salt Lake to have him look at the disks. He said the I not have to replace the bobbins because they were not loose. He checked them by trying to move the disks back and forth parallel with the wheel and there was very little movement. SO thanks for all the input and I will print them out fo later reference.
