Michael Hardman Posted July 24, 2005 Report Share Posted July 24, 2005 (edited) I just got my front mini back from hope to sort out a leak and I go and bed it in and have problems more leaking I sanded the pads and disc down and taped up the leaking part temporaily. The proboem now is when I pull the brake the pads stick to the rotor and require a little force to free again. I realy cant work out whats wrong Ive not put any glue on it and maybe my brake is just workingt o well its al a mystry to me. Maybe I have heated the pads up too mcuh and some has been left on the rotor I dont ahve a clue any ideas.

Mr Motivator Posted July 24, 2005 Report Share Posted July 24, 2005 Sounds like they need to bed in again. Put water on your rotor and ride around for a bit using the brake here and there. Then let it dry off, then put more water on and repeat until they no longer stick. My pads were sticking when I first got my disk, now they're fine :) Quote Link to comment Share on other sites More sharing options...
philking Posted July 24, 2005 Report Share Posted July 24, 2005 What, so hope fixed one leak, and it came back with another? Sounds like sticking pads are the least of your problems... Where is it leaking from now? Quote Link to comment Share on other sites More sharing options...
Michael Hardman Posted July 24, 2005 Author Report Share Posted July 24, 2005 Sorry should of explained the second leak as Dave pointe dout to me could be from excess fluid in the bleed nipple which I have sorte dnow and also the top cap being too tight which is also sorted. The brake brakes perfectly well better than it used to just I have some plumbers tape on a few bits now to prevent fluid going on the disc as a precaution. Il carry on bedding it in athough it is super sharp already. Quote Link to comment Share on other sites More sharing options...
Michael Hardman Posted July 24, 2005 Author Report Share Posted July 24, 2005 I just found out my rotor bolts were loose and hitting on the forks hence the sticking. Although I now have another problem the lever now hits the handle bar when I pull it in, it did it when I turned the bike upside aswell. Is this a case of there not being enough fluid in the systemif so I can sort that when I find a screwdriver to fit. Quote Link to comment Share on other sites More sharing options...

I avent used my bike since putting the brake back on to bed in. Quote Link to comment Share on other sites More sharing options...

However, given hope just did it for you especially, it should be perfect. It sounds to me like the leaking which you thought was from excess fluid, was actually due to a system fault... dogey seals maybe. Ring hope and explain the exact problem, and they should sort you properly this time. Quote Link to comment Share on other sites More sharing options...
modrider666 Posted July 24, 2005 Report Share Posted July 24, 2005 I have the exact same problem on my momo mini. My disc got contaminayed so i sanded the pads down slightly. Now when i pull my lever in the pads stick, but pushing the lever out unsticks them :) . Hmm strange Quote Link to comment Share on other sites More sharing options...
Lee_Buchanan Posted July 24, 2005 Report Share Posted July 24, 2005 Hope are experiecing alot of problems apperently with the brake,with the pistons starting to stick.And all the fluid is only in one fluid that is why there is nothing there on the lever when you pull it. Alot of people are having to take there brake to hope because of pistons sticking etc.I had two take mine down last week for the exact same reason my lever was pulling into the bar and there was fluid in there its something to do with a fault with the pistons....or so iam told. Best thing to do would be to tell hope whats happening over the phone and see what they say.Suppose its a big advantage when you live near and you can just nip down.

Michael Hardman Posted July 24, 2005 Author Report Share Posted July 24, 2005 The sticking problem has gone it was losse bolts hitting the fork leg now its the lever pulling all the way to the bars. Im gonna top it up 2morra it may have something to do with the sanding the pads I think I took alot off judging by the state of the sandpaper. Maybe there was only enough fluid in the system for the amount of pad now theres less pad ther emay not be enough fluid to push the pads far enough Quote Link to comment Share on other sites More sharing options...
philking Posted July 24, 2005 Report Share Posted July 24, 2005 The brakes auto-ajust and should be able to push the pistons out far enoughto use ALL of the pad compound... It is a strange problem but with a sufficient bleed there shouldnt be any problem with what you have described. Quote Link to comment Share on other sites More sharing options...
Michael Hardman Posted July 25, 2005 Author Report Share Posted July 25, 2005 The resersvoir was less than half full so Ive topped it up and adjusted the lever reach and now it seems fine. Although theres another problem I think. Ever no and again I put the brake on and it squeels then after re applying the brake for a minute or two the squeel has gone. This brake is confusing the hell out of me. It all seems ok now apart from the rounded bolts which I think I better replace soonish Quote Link to comment Share on other sites More sharing options...
JIX Posted July 25, 2005 Report Share Posted July 25, 2005 Do u mean u rounded off the resevoiur (sp?) top cap bolts? I have done that to, it is silly to use 2mm bolts there, I had to drill the hole on the top slightly wider and use a srewdriver. Dont think i will get new bolts as it will just happen again. :turned: Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted July 25, 2005 Report Share Posted July 25, 2005 What exactly is wrong now Mike? If you could outline the problems one by one please, I can tell you the solutions. You don't wanna go filling the reservoir up all the way (with the pistons out), since it then allows no room for heat expansion, and won't let your pads retract - hence the rubbing If the pistons are sticking, you need to lube them. Use silicone spray (the sort of thing car garages use on car dashboards to make them look shiny) to do this. Quote Link to comment Share on other sites More sharing options...
Michael Hardman Posted July 25, 2005 Author Report Share Posted July 25, 2005 Right there is no sticking problem now that was mystupiduty not seeing the rotro bolts loose and hitting the forks. The only problem now is the occassional squeeling from the brake which comes and then goes. There is a bit of leaking from the reservior cap but Im going to buy a new one soon as my one is worn Quote Link to comment Share on other sites More sharing options...

The first one means your brake is working well, the second means your mounts need facing and the caliper re-aligning. Either way, having the brake over-full won't help with the rubbing. Wheres the leaking from? The little square hole on the side? If so, just wipe it up, that perfectly normal after a brake has been bled, and will stop soon.

Michael Hardman Posted July 25, 2005 Author Report Share Posted July 25, 2005 (edited) I think its the first type of squeel although it still reminds me of the squeel you get when you spill fluid on the disc and contaiminate the thing. The leaking isnt that much of a biggy seeing as it only the reservior and its a nice long way away from my disc. Cheers everyone Im off to keep bedding it in seeingas its raiing ideal weather for it.
