    If you have not removed the brake pads, that tells me you have not rebuilt the calipers. Start there FIRST! You said you rebuilt the master cylinders, why didn't you do the calipers at the same time?? It just means you'll have to go through the whole bleeding process all over again. You'll be amazed at what a difference it makes when you clean the piston seal groove. The seal has to slide up and down in that bore, and if that groove is full of gunk, it gets tight enough to snag the piston and make the brakes stick. Make sure you go through all 3 calipers. This is one of those things that does NOT fall into the "If it ain't broke, don't fix it" category. Take the time to make sure they are all clean. It just may save your life one day...

      thing is, the only Special I have ever seen up close is my own XS11SG and the only other XS11 I could easily go look at is a '78 Standard so I did not know that about the LH.
      Q1) HTF do they mount a swivelly caliper on the LH swingarm?
      Q2) Does your LH have the axle on the front of the slider like other Specials and if so could I swap LH sliders onto my SG and thus get normal front calipers without increasing the front wheel trail?
      Q3) Or did a dreaded PO swap in Standard fork legs on your bike?
      1. The swivel caliper mounts to a bracket that connects to the axle and a pivot pin on the inside of the swingarm. One bolt goes through from the back to the front to mount the caliper to the bracket.

      2. Yes, the axle is on the front of the forks, just like the other Specials. There are 2 bolts on the trailing edge of the forks where the calipers bolt on. I don't think it would be possible to do a direct swap without swapping the actual forks. However, if you did swap the forks, it would not touch the front wheel trailing angle.

      3.Nope. I have the original forks. That's the way the LH was designed. Just like the XJ.

      I've tried to study the parts diagrams of the MNS's so I would know the differences between them, and the differences between the MNS's and the other models. It's tough keeping track!

        Hi 'Bug,
        I just checked out Gator's pic of his XS11SH and it's got straight spoked mags and ATE front calipers just like my XS11SG.
        But the pic of your XS11LH shows the XJ's swirly mags and from what you say, it's front calipers too.
        Yamaha's "parts swap like LEGO" design policy is good if you are looking for something that could fit one of Yamaha's one year wonders but it can make for complicated research.

          Thanks bug. I'll give that a shot. I should have known that. It's the same with autos. Guess i think that bikes are different.

            No kidding!! I discovered that when working on the rear brakes on mine. It has the linked brakes of the XJ, but a different size MC, for which no one makes a rebuild kit anymore! I had to upgrade to the XJ MC just so I could find a rebuild kit for it.

              Hi newbie, I'm pretty new too but I think you might be on the right track with the pedal adjustment. I got the pushrod too tight on mine once and it did pretty much the same thing.
              Anything expands with heat and if it's just a little too tight the heat would push it over the edge.

              I used to live in Port Angeles and I know ya'll have had some record heat there in Washington this summer. Probably caused all kinds of problems.

              I'm not an expert but it seems to make some sense. Try loosening it a bit.

                water and oil, dot3 and dot4

                Well here's my $0.02 and if you've already tried it just disregard. My brakes were fine and while I was bobbing out my xs they decided to do the same thing so I did this Click Here also I've heard that if you mix dot3 with dot 4 it can cause the fluid to get thick and jelled which would cause the spooge hole to plug. Not sure if that is true but I didn't take the chance I drained and rebuilt the master cylinder and the calipers and replaced all the fluid with the recommended dot3 and the work great now. Good luck and let us know what it ended up being.

                  New fluid is good

                  Hi Chop,
                  DOT3 & DOT4 mix together just fine. The only difference between the two is that DOT4 has a higher temperature rating.
                  The latest can of brake fluid I bought claims to be DOT3/DOT4 Synthetic.
                  OTOH DOT3 or DOT4 don't get along with DOT5 because DOT5 is a different recipe of chemical soup and mixing can pickle them.
                  So the recommended annual brake fluid renewal by just pumping the old fluid out of the bleeder and topping up with new fluid works EXCEPT if you are (for whatever reason) swapping DOT3/4 to or from DOT5.
                  Then you should do a complete brake teardown & cleaning job to ensure the two types of fluid never meet.

                    Correction Dot5 not to be mixed with

                    That's it! I knew there was one that was not friendly to the other but I couldn't remember what one it was, thanks for straightening that one out. I figured that somebody knew though, So for sure then Dot 3 and 4 can't be mixed with Dot 5! Thanks again Fred you saved the day one more time.

                      Well i took my rear caliper off and opened it up. It wasn't really dirty, but there was a little gunk under the piston seal. Cleaned everything up, reinstalled it, bled it out, and went for a test drive. Everything went fine with no freezing. The other thing i did was adjust the pedal linkage. I left it just a tad looser than the book calls for. Now i don't know for sure which one was the problem. I do think though that the caliper was the problem. It doesn't take much to cause clearance problems.

                        If you recall cleaning the area under the seal was recommended early in the discussion...
