lshark Posted September 18, 2014 Share Posted September 18, 2014 the pad pins can get a layer of road funk and brake dust built up on them...i took some med sandpaper and some brake cleaner, put an allen key in the drill and sanded them clean ...wanted to replace them last brake job but they were back ordered Link to comment Share on other sites More sharing options...
zaq123 Posted September 18, 2014 Share Posted September 18, 2014 I wouldn't send those pins. They are steel and will corrode once you take their coating off. I'd use some brass brush on them or get a replacement if they are very bad. Link to comment Share on other sites More sharing options...
lshark Posted September 18, 2014 Share Posted September 18, 2014 there is no coating on them, the rust is what i was sanding off... the movement of the pads would remove any coating Link to comment Share on other sites More sharing options...
Member Contributer Dutchy Posted September 19, 2014 Member Contributer Share Posted September 19, 2014 Contact Pro-Bolt.co.uk and ask when they will have the titanium slider pins for the VFR1200 perhaps? Link to comment Share on other sites More sharing options...
Guest Posted September 22, 2014 Share Posted September 22, 2014 Ok Guys a bit of an update and help still needed.. I have removed front calipers. Cleaned all the pads, pins, clips and pistons. I used very fine sand paper on the pins and clips to clean them up. Copper grease on the back of the pads, pins and bolts. All assembled correctly and torqued as per the workshop manual. CLICKING NOISE IS STILL THERE :excl2: What the hell is causing it? I was out for a spirited spin yesterday and I just don't have confidence in the bike like I used to, I would at least like to know definitively where it is coming, whatever about stopping it! Symptoms again: I wheel the bike backwards and apply the front brake to stop the bike and when I release the brake lever a clicking noise comes from the caliper area!! Any help much appreciated Link to comment Share on other sites More sharing options...
lshark Posted September 22, 2014 Share Posted September 22, 2014 does the bike have to be moving backwards for it to click or does it do it once stopped....will it do it if you raise the front end and spin it backwards by hand?? one click, multiple clicks ?? can you post a video ?

Yes it only happens when you are pulling the bars backwards i.e backing it out of the garage. It does not do it when going forwards. One click as you are releasing the brake lever. I can let the suspension etc settle down for say 10sec while holding the brake lever and it will still click when I release it. Which leads me to believe it is not a headstock bearing etc. It sounds like it could be the pads moving away from the disc,but they only move a fraction of an inch surly you would not hear them. Could it be the disc bobbins on the floating disc? I will try make a video tonight. Link to comment Share on other sites More sharing options...
Member Contributer Switchblade Posted September 22, 2014 Member Contributer Share Posted September 22, 2014 I am wondering if you have a bent or warp rotor. Link to comment Share on other sites More sharing options...
zaq123 Posted September 24, 2014 Share Posted September 24, 2014 I am wondering if you have a bent or warp rotor. no, unlikely. I'd say bobbins in the rotor which would be perfectly normal but vfr12 rotor are so darn tight and semi-floating, it is very unlikely. If this only occurs when spinning backwards, most likely something to do with your pads or pad springs. Something happens when pads grab the disk and go counterclockwise in the caliper, not clockwise. Raise your front, pinpoint which side is doing it (left or right), swap large pads from the left rotor to the right one, see if noise is still on that side. If it is, swap small pads from left to right. If still there, swap pad springs from left to right. Get the idea? Link to comment Share on other sites More sharing options...

lshark Posted September 24, 2014 Share Posted September 24, 2014 it sounds to me like the pads might be moving out of position when they grab the rotor moving backwards and maybe jamming against the pad springs...try getting the front wheel off of the ground and spinning it backwards by hand and watching as the pads grip and release Link to comment Share on other sites More sharing options...
Guest Posted October 6, 2014 Share Posted October 6, 2014 Ok everyone its been a long time coming I know but here is a link to the video of the clicking noise. Its not the best video in the word but let me know what you think and I can make another video if needs be.http://youtu.be/bN85h5cPqAg Link to comment Share on other sites More sharing options...

Guest Posted October 6, 2014 Share Posted October 6, 2014 what kind of rotors are those ?? They are EBC rotors and EBC Pads. All fitted under warranty by my honda dealer were I bought my vfr. Link to comment Share on other sites More sharing options...
Member Contributer Switchblade Posted October 6, 2014 Member Contributer Share Posted October 6, 2014 It sounds like to me the edge the pad is catching on the drill holes in the rotor. Or the steering head bearing , if you jack it up and spin it by hand and stop it, does it make the same sound ? Link to comment Share on other sites More sharing options...
Taycio Posted October 6, 2014 Share Posted October 6, 2014 i think what you are hearing is the pad springing against the anti vibe panels. Remember a brake is only supposed to operate in the forward direction. I think that if you watch the pad it will move slightly in the caliper maybe only a millimeter or two. It will probly be a normal noise that you will hear under those conditions... Link to comment Share on other sites More sharing options...
Member Contributer Switchblade Posted October 6, 2014 Member Contributer Share Posted October 6, 2014 either that or one of the rotor's is popping in and out. Link to comment Share on other sites More sharing options...

When rolling backwards it could ride up on the top side of the valley and then when release the brake it "pops" back into into place. You need another person to push it while you watch the spring and see if it is. Link to comment Share on other sites More sharing options...

Member Contributer Switchblade Posted October 7, 2014 Member Contributer Share Posted October 7, 2014 that pic is of my bike so he could compare 10-4 Thanks but do you think the pad is forcing the retainer or tension spring to push up and hang in the little valley's ?

Member Contributer swimmer Posted October 7, 2014 Member Contributer Share Posted October 7, 2014 Its not the best video in the world You are selling yourself short. That might actually be the best video in the world. Get another person and have one person initiate the clicking noise while the other person touches the calipers, ends of pads, etc... until you isolate it.
