  • Cleaning floating disk buttons

    Hi all,

    My Speedy has been developing some pulsing while braking (front) over the last month, and while I initially thought I had managed to warp the rotors, the ever helpful interwebs pointed me to the buttons on the floating disks.
    So I checked and found that the majority had little to no movement if you tried to rotate them by hand.

    Further interwebs searching suggested that I do the bolt, washer and plenty of brake cleaner technique - which I am in the process of doing, but am finding that it is very time consuming, fiddly, uses a S**t of brake cleaner and I find they are still fairly tight when rotated by hand.

    So my questions are:

    How tight/loose should they be normally?
    Does anyone have any pro tips to make the job easier - or do I just need to suck it up princess, set a few hours aside and buy a couple more cans of brake cleaner?

      ... so the latter?

      Toothbrushes aren't a problem, I have plenty in her 'Bath Day' bucket.

      As for the disk cleaner, I have been using the Repco generic brand, no good...?

        All the same really, how bad are you discs? Can you post a pic?

          They are only semi-floating discs so don't expect too much movement in the buttons.
          I suspect you either have some glazing or uneven pad deposits on the rotor itself. I use one of these every 6 months or so and give the surface a good clean. It fits in a drill.>>> disc cleaning rotor hone

              Thank [MENTION=27425]Mr Bean[/MENTION] , there is definitely some glazing, with the associated brake squeal. I have been told a light brush with some emery paper will help with that (the pad, not the disk), is this right?

              I had earlier given the rotors a good scrub with brake cleaner, thinking it may be resin/deposits, but had not joy in resolving the issue, however I didn't use any tool like a rotary brush, and I am always looking for an excuse to add to the tool box

                Are you sure they're not warped? Have you put them on a dial gauge? Triumph rotors are very prone to warping.
                Fairly sure they're only semi-floating rotors so you wont get any forward/backward movement on those buttons, only side to side.

                  I can't be 100% sure, and I have no way of lifting the front to check with a dial gauge or blue tac/paper clip.
                  I am hoping to rule out any normal wear'n'tear things before going back to the dealer - she is still under warranty.
                  I wasnt sure if rotors would be covered, but have read the warranty a couple of times over and while it stipulates that consumables such as pads etc aren't included, it makes no mention of rotors.

                        Very nice, I could definately see a pair of those on my front wheel. Probably looking about a grand for the pair after postage, exchange rates etc, which would dig into the toy fund a bit much.

                          Finally got around to sorting it out. Ended buying a front paddock stand and pulling the wheel off, then removing the disks and giving them a good scrub with the toothbrush/brake cleaner. I found this to be much better than trying to scrub them on the bike and gave me a chance to give the calipers a good clean. Funnily enough, I found my mates oral b toothbrush did a better job than the cheaper brush I started with.

                          I gave the locktight a chance to cure, and have had it out for a ride this arvo. No squeal or pulsing from the front end for now, happy days
