I have a rear brake now!!!!!! 89 R100GS I replaced the brake shoes (original glazed over shoes) with a set of EBC 861 shoes and now I have a rear brake that works!! The EBC 861 is the correct part for this bike. Most of the catalogs refer to the EBC 859 which is the wrong part. See this link for a good photo of the shoes that are correct. http://www.beemerboneyard.com/ebc861.html Do remove your old shoes and confirm you are getting the correct part.
