    front brakes - right easy, left resistance.

    When I got the XJ11 last Oct, when pushing it or sitting on it I could turn right and push/walk it foreward with no problem. When turning left though it would have resistance and feel like the brakes were dragging. turn the wheel a bit more straight and it eased. Going straight or with the wheel to the right was no problem. I assumed the L caliper was sticking.

    I've rebuilt all three calipers and replaced all hoses with Teflon lines with SS braid. While moving the bike inside & out of the garage to work on the engine I see the problem is still there which means it's not the lines, brakes or calipers that is at issue. When the calipers were off the wheel turned freely and I didn't notice this problem.

    Idears?

    I don't know why it would feel more resistant turning to the left but it won't be brakes. Brakes would affect it ALL the time. Right, left, foward or backward.

      I should have titled this as wheel rotation, not brakes. Realized that too late to change it..

      I can only think that when the brakes /calipers are off there's no problem but when on, there is. Not sure what that means as to what's off but I know the calipers /brakes/hoses went on easy & with no issues.

        Clean the spooge hole

        My theory is when turning left you are squeezing the hose enough to create brake pressure. This wouldnt happen if return hole wasnt blocked as there is nowhere for that mild pressure to go but push the piston.

          The only thing I can think of that makes sense is possibly a loose wheel bearing binding the rotor on the caliper in left turn conditions.

            JW, Yeah, that was on my mind when I rebuilt the brakes & I cleared the spooge hole in the MC. I checked to see if there was any binding with the new brake lines and there's no tugging at full rotation on either of the lines.

            BA, would such a thing be silent? There's no bearing noises when I move the bike.

            FWIW, If for discussion's sake a wheel rotates 45 degrees from straight, the issue begins to come on at roughly 15-20 degrees of turn to the left.

              What John is saying is possible but not probable as far as I can see.

              Possibly rear swingarm alignment or bent frame?

                I'll throw this out there for checking... maybe it's the brake hose (the braided varity is stiffer than rubber hoses) causing the caliper to pivot on its mounting bolt. I know there's been comments about the braided lines for the XS needing some 'twisting' of the ends to get them to align, maybe the hose is moving the caliper. I would think any bearing that loose you should be able to spot by applying off-axis pressure to it...

                  Just put the bike on the center stand and get something under the front of the frame to hold the front wheel off the ground so you can check for side to side movement.

                  Just brain stormin' and throwing things out there, stuff to check.

                  You said it only does it with the calipers installed, push the pistons all the way in and try it with the calipers installed. If it still does it its not hydraulic it's mechanical.

                    I have fought this problem for over a year as well. I have been unable to isolate it. Mine is minor, but it is also with a left turn. I am starting to think that it is wear in the caliper mounting.

                      I'm wondering how the caliper would move without applying the brake Newb?

                        Mine is "minor" in that it didn't slow down the bike when I was turning during the couple of weeks I rode it. It was obvious when the bike was stopped and I'd turn the wheel left and start to walk when sitting on it, or when jockeying the bike into position while off the bike and pushing it while holding the handlebars. The resistance at max wheel rotation was noticeable but in riding that degree of wheeling left would never be encountered.

                        So not an issue for riding but I know it shouldn't be there at all and I want to find the problem gone.

                        I know the right rotor had been changed in the past as there was some of that yellow paint marker recyclers use on the inner part of it. Both rotors look the same though and both are thick and showing very little use.

                        I did... think replacing all the hoses, brakes and rebuilding the calipers would have resolved the problems from last year.

                        Would a problem with the forks cause this? I didn't notice any tracking issues when driving it last year. Still don't have it running right now but it is acting as before, no improvement & it's not any worse.

                          on the Special, the caliper has a little slop, because of the way the caliper mounts, so the minor slop could allow movement when the head is turned. I have moved my hoses around, up and down. On the plus side, this has not bothered me while riding, and this has been 10,000 miles this last year.

                            I know how the caliper mounts and works. I have 3 specials. None of which this problem occurs on.

                            I still dont understand your thinking. The calipers don't do anything by themselves.

                            Not trying to be arguementive, I just don't see your reasoning. If the piston isn't actuated the caliper just hangs there. Something mechanical would have to move the caliper/pads into the rotor, or the rotor would have to be moved ,somehow, into the caliper/ pads.

                              You are right in your thinking Greg. Just got a fart caught sideways. Mine has been going so long, i quit worrying about it.
