I have a 1985 R80RT with about 25k miles on it. I am the original owner. Since I have owned this bike, the front disk breaks have squeaked. I recently put new pads on the front and now it is worse than ever. I have had 2 different BMW dealers look at them. They just shrug and say "not much you can do". I am hoping someone out there has proved them wrong. I have tried cleaning them and putting disk break quit coatings on the back of the pads, but this has done nothing. Other than the squeaking they work just fine.
Thanks!

Yeah, my 85 R80's font brakes tend to squeak a bit. Long as it stops fine, I just let'm squeak.

Clymer's shows a caliper alignment procedure for the type A caliper on my R100/7. I immediately removed 90% of my squeel with a simple screwdriver adj. I will do the fine tune this winter. Seems that your BMW dealer would have known!

My '88 R100RT squeals alot, but it stops fine. I look at this way, it's one more way to draw attention of the drivers around me. However, let me know if you are able to quiet them down. (my local dealer had no real suggestions either)

You might try the anti-squeal paste found at most auto stors. It goes on between the pad and brake piston. It worked for me

Proper adjustment of the caliper and switching from a "sintered metal" brake pad to an "organic" compound should help too. I believe the OEM pads from BMW are the sintered variety.

First of all, there is no "caliper adjustment" on BMW Airheads post 1980. A bit earlier, i.e. from the beginning, for the R65.

Things must be straight and true, however, and this relies on flat rotors, properly aligned forks, etc. Both pistons in the caliper must be operational, not just one.

After that, it's mostly up to proper lubrication of areas of the pad where it contacts the piston and on its edges where it can contact the caliper body. Clean the caliper areas Expect to have to relube before a set of pads wears out. Replace pads contaminated with grease or the like.
