    Hi there!!

    Im having a few problems with my rear brake on my 2008 focus killer bee mtb.I bought the bike second hand two weeks ago and must say really pleased with the bike except after leaving standing in garrage for two days iv lost all the rear brake .The brakes are shimano xt.So i bought some shimano mineral oil and bled the system by topping up resivoir and bleading through the nipple on the calliper.After some time brake finally came back and i thought it was all sorted.However gone to use the bike today and same thing has happend again.

    Does anyone have any idease what the problem could be.Is it possible i didnt blead the system properly the first time and there may have been iar left in there.

    Also my front brake is creaking like mad is there any quick fixes to stop this and the overall performance is not very good i think may be the pads are contaminated is there any ways to recover them as they still got plenty left on them.

    Any advice would be apreicated Regards iash101

    😆 I hate disc brakes. They’re only necessary for competitions, they’re just unecessary problems for normal riding. I’m converting back to cantilevers.

    Try some talc powder on the pads or someother fine powder, or try screaming back at them. Or just get some new pads.

    Try using a syringe and pumping the oil back up through the bleed nipple into the reservoir after taking the cap off. The other thing to look for is to see if the hose has been squashed any where along it’s length. I had this problem, on mine a few weeks back. Replaced the hose, bled it through and it’s like new.

    As for the front, either put new pads in, or get some disc brake cleaner. Pads could be contaminated.

    Hi Guys!!

    Just a little update on Brake problems.

    I read on the net that baking the pads at 220 degrees for 20 mins decontaminates the pads.So i done this and the brake is now much ,much better .I also put some copper grease on the rear of the pads oh! I also cleaned rotas with some thinners and am verry happy as the squeel has gone .

    As for the rea bled every thing was fine for a day then same thing happend just lost all brake again. Iv just noticed brake fliud dripping from hose.Therse a bulge and hole in pipe .Im not sure if theres been a little hole there all along and thats been my problem or the hole has developed whilst bleding the system.

    Does any one know if bleeding would be possible with a tiny hole in hose?

    Also does any one know if this pipe on ebay will fit shimano xt ? Ill attach a link bellow its for shimano m525/535

    cheers guys iash101
