    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.

    Do remove your old shoes and confirm you are getting the correct part.:deal

    I guess I'll find out when I remove the old ones.

    Part # 861 looks like what I have in my G/S.
    The ones I've seen in the GS look differrent and are slightly wider.

    I just dragged out my spare set of OEM brake shoes for my '94 and they look just like the 859 variety.

    You're welcome. How did your pivot pin issue work out?

    I cleaned and tightened, so far so good.
    Planning on replacing the pivot pin and needle bearing over the winter.

    How is the search for another bike going ?

    Poorly. If you hear of any leads over there, pass them on.

    I had my g/s apart... Brakes are like 861

    As I recall my GS is like 859 which is confirmed by jackd

    Looks like a difference between monolever and paralever.

    Biebs.... It is confusing that a 89 paralever has 861 pads... Pics would be good

    I went through the 859/861 insanity last summer. After ordering what turned out to be the wrong shoe for my 89 R100 GS, I had a very knowledgable long time BMW mechanic, who also happens to be my brother, order the right shoe for me. I was going to be at his shop anyway, so I figured he could get the part and we'd put them on when I got there. He, and a very reliable Dealer in Montana both showed the 859, so he ordered the wrong set too. He knew immediately when he saw the shoe that this was the wrong shoe for my bike.

    Long story longer, said mechanic and said dealer started going back through old invoices. Turns out that EBC changed the part number, or got it screwed up in their computer system, for that shoe that is used in many, many, pre 1994 BMWs sometime in the last few years. Prior, they had both always ordered 861. Unfortunately, a majority of parts fiches and online sites now show the 859, but that is incorrect. The 861 is the right part.

    It must be early in the morning for me but your last post kind of puzzled me. The 861 is the right part number for what? If you are suggesting it applies to the later model GS's, I would say you are incorrect.

    Does this make any clearer? or am I missing something? I am going to order a pair of 861s and 859s soon for the bikes.

    The only way this could be wrong is if the pictures are mixed up on the Beemerboneyard site?

    861 = G/S --- this listing shows only up to '87. does NOT show use for R100GS

    http://www.beemerboneyard.com/ebc861.html

    859 = GS --- this listing shows ~87 and up. does NOT show use for G/S model

    http://www.beemerboneyard.com/ebc859.html

    This confirmed by looking at my own G/S and GS

    My 89 R100GS, definitely not G/S, takes the 861 as shown in the photos above, as does my brothers 81 R80 G/S.

    I found several listings, many listings, every listing I saw, that said what I needed was the 859. They were all wrong. But I would take everyone else's word as to what you need - seriously, I know nothing about a 94. Or just pull off the rear wheel and look. My experience was very frustrating and expensive.

    I have a 91GS and it takes 859. So it looks like somewhere along the way that the GS changed their brakes...

    looking at MaxBMW at 87-90 GS the rear brakes call out different part numbers. One for below 09/89 and another for above 09/89

    So it's not G/S versus GS... it's:

    Older than 09/89 = 861
    Younger than 09/89 = 859


    Yikes:huh

    Now that's interesting. I have no idea what month mine was manufactured. I don't know if any of the placards are still that legible. I suppose if I ran the serial number from the frame I could find out.

    Why don't you just pull the wheel off? You might not even need new brake pads.

    Look at your brake shoes before ordering!!! Difference is obvious.

    Listing on the internet are wrong so order the part you need!!!

    I was lucky my local BMW speciallty shop had both sets in stock - I took the original brake shoes with me and got the correct set.

    If ordering on the interweb do look first and do not go by the listing posted.


    Photos posted are what you should be looking at do you due diligence before ordering!!!

    This information is questionable / not correct!! :eek1 as posted by another user.

    So it's not G/S versus GS... it's:

    Older than 09/89 = 861
    Younger than 09/89 = 859
