    rear brake problems

    Ok, so I'm still very new to motorcycles so forgive me in advance if these are stupid questions but I can't seem to find the right answers searching in the forums.. Recently I took the rear wheel off of my '78 750E for the first time to have the tire replaced and to change the sprockets and chain. Everything went smooth until it came time to put the wheel back on and the disk wouldn't fit in the caliper. Looked on the forums and came to the conclusion of taking every rear brake part off; caliper, lines, MC, and replacing all that i couldn't just clean up. I put everything back on and it fits better but still no dice. In the pic you can see the brake disk wont fit evenly in the middle of the caliper and the right pad drags. I've checked all the spacers to make sure they were in the right order and I'm pretty sure I'm not missing any. Also the brake pedal has locked up. I've tried tapping out the rod but it just won't budge and I don't want to use too much force in fear of messing up the grooves that hold the pedal in place. These seem like they would be somewhat easy fixes if I could figure out how to resolve the problem and spending $$$ at a shop isn't really an option. Thanks for your time

    the only real explanation i can see is that there is a mix up in the spacers somewhere. i know you say you have checked and think they are all correct but i suggest you remove the wheel again and recheck all the spacers are in the correct places.
    if you have a manual then refer to that or if not refer to an on line fiche picture showing which spacers go where.

      Yup I agree, looks like a misplaced spacer. Surprised you got it on at all. How big was the hammer? lol

        Looks like you have the spacer on the outside of the brake caliper mount and it should be between the wheel and caliper mount, just reversed from what you have.

            it appears that you have omitted part #7, the spacer, looking at the fiche picture

              That one pic really doesn't show anything except the caliper up against the disk.
              Something has got to be out of order, or not mated correctly. I think were talking only about 1/16 to 3/16 of an inch to get it to center up.
              Here's another fiche you can look at.

                The spacer against the swing arm goes in between the wheel and brake stay.

                  that is the fiche pic, if #7 is missing then tightening up the rear axle is going to force the caliper onto the disc, locking it up. with that spacer in place the caliper and bracket wont be pushed in so far

                    no, if you look on the fiche picture there IS a spacer outer of the caliper bracket., #17.
                    #7 is what is missing

                      Bill,
                      If you're talking about that spacer, no. 17 on the fiche, I say I don't think so.
                      Now, these pics are not from a GS750, but my '79 GS1000EN and it shows the spacer on the outside of the brake stay.

                        I can't help but wonder if it would make any difference if the spacer that goes between the brake stay and what I believe is the bearing, or (No. 7) or whatever part no 4 is turned around.
                        Here's another pic from my GS1000.

                          Steve, it wouldnt make a lot of difference, unless it is MISSING!

                              its the spacer between the caliper bracket and the bearing that is missing, it is obvious when you think about it.
                              either that or he HAS missed out the spacer between the 2 bearings and tightening the axle is forcing the right side to far into the wheel, OR, he has the wrong bearings fitted.
