ZeroMatt Posted November 19, 2008 Report Share Posted November 19, 2008 If the wheel has moved in the dropouts at all it will be that the rotor is on the piss relative to the pads making it shit. Quote Link to comment Share on other sites More sharing options...

Skoze Posted November 19, 2008 Report Share Posted November 19, 2008 (edited) cleaned the pads/ rotor?Edit: the simple things always sort mine out Edited November 19, 2008 by Skoze Quote Link to comment Share on other sites More sharing options...
walker Posted November 19, 2008 Report Share Posted November 19, 2008 Has any oil got on the rotor or pads? check the seals of the slave cylinders. Quote Link to comment Share on other sites More sharing options...
N.Wood Posted November 19, 2008 Report Share Posted November 19, 2008 Checked for leaks around the caliper?Make that nice 'i'm contaminated with shit' sound? Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted November 19, 2008 Author Report Share Posted November 19, 2008 Ill examine now.. Quote Link to comment Share on other sites More sharing options...
forteh Posted November 19, 2008 Report Share Posted November 19, 2008 (edited) Hope trial.Erm..when i say shit..i mean i pull it and it doesnt lock..Contaminated pads/disk? Does it squeal/honk at all?A misaligned caliper will make the brake feel spongey and it will lose its bite but the hold should still be ok.edit: goddamit 3 seperate people posted the same thing whilst I was typing Edited November 19, 2008 by forteh Quote Link to comment Share on other sites More sharing options...
Skoze Posted November 19, 2008 Report Share Posted November 19, 2008 Check round the reservoir cap too, my old one seemed to take a liking to diaphrams! Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted November 19, 2008 Author Report Share Posted November 19, 2008 Its leaking from somewhere..its all abit wet .. Quote Link to comment Share on other sites More sharing options...
forteh Posted November 19, 2008 Report Share Posted November 19, 2008 Check round the reservoir cap too, my old one seemed to take a liking to diaphrams!Dont tighten them up too much, it deforms the diaphragm and causes them to weep Its leaking from somewhere..its all abit wet ..Get cleaning then Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted November 19, 2008 Author Report Share Posted November 19, 2008 Get cleaning then But how do i stop the leaking? LOL Quote Link to comment Share on other sites More sharing options...
Mat Smith! Posted November 19, 2008 Report Share Posted November 19, 2008 But how do i stop the leaking? LOLTighten everything/change hose/check seals.Mat Quote Link to comment Share on other sites More sharing options...
forteh Posted November 19, 2008 Report Share Posted November 19, 2008 But how do i stop the leaking? LOLFind out where its leaking from and fix it It will either be the bleed nipple, piston seals or banjo bolt; take the caliper off, clean it all down and try squeezing the brake with something between the pistons to pressurise the system - any leaks should become apparant.Check the banjo bolt and bleed nipple are tight, could be you kicked the hose with your heel and its slackened off enough to weep. If its the piston seals that are gone you will need a new pair of seals, the hope borecap tool to take it apart and a rebleed.Could always send it back to adam to check over if you cant find the fault Chances are that you may need a new pair of pads aswell depending whether or not you can burn out all the oil, unlikely to be 100% again though Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted November 19, 2008 Author Report Share Posted November 19, 2008 Just loosned off the bolt..that allows you to move the cable in whichever direction you want. and a shit load of oil just come out..Just did it back up and now the level pulls the bar. BRILLIANT.Re-Bleed?? How? Lol Quote Link to comment Share on other sites More sharing options...
psycholist Posted November 19, 2008 Report Share Posted November 19, 2008 If no air bubble got into the brake when it leaked (If the lever didn't feel too spongy before the extra fluid leaked out), just take the reservoir cap off, pour more brake fluid in and pump the lever, making sure the lever reservoir is at the highest point in the brake. Pulling the lever and letting it go suddenly tends to drag bubbles through the top of the system more quickly - lever the pads as far apart as possible to drive more fluid towards the lever. Bubbles should appear in the reservoir for a while, then stop appearing, hopefully coinciding with the brake no longer feeling spongy. If the lever is still spongy after trying this you'll have to do a full bleed. Instructions for this are around the place - the basic rules are:1. Bleed from the lowest point in the system to the highest point.2. Make sure you don't pump more air in at the low point when you attach/remove the syringe.3. When replacing the reservoir cover make sure you don't trap any air bubbles at the lever by rolling the diaphragm onto the top of the reservoir, displacing brake fluid, rather than putting it in flat.

crispyboy Posted November 19, 2008 Report Share Posted November 19, 2008 Also the brake could feel spongy because you might have bent the disc Quote Link to comment Share on other sites More sharing options...
Joe Papasnap Maher Posted November 19, 2008 Author Report Share Posted November 19, 2008 Take it to your local bike shop? If you even have one? I dunno what the deal is over there Ive never bled a disc before..but im quite sure id rather sort it out than let any other people play about with it...Ill work it out..Ill be heading over to the wiki to get full instructions..even though none of it makes sense Quote Link to comment Share on other sites More sharing options...
Andrex Posted November 19, 2008 Report Share Posted November 19, 2008 If you were over here, I could do it for you, but because you are not, I can't. It's much easier than you think to bleed a hope. Just make sure you don't get fluid over pads and disc. Quote Link to comment Share on other sites More sharing options...
N Roach Posted November 19, 2008 Report Share Posted November 19, 2008 (edited) 1.) Take the cap off the master chamber on the lever (keep lever level)2.) Undo the bleed bolt on the brake cylinder, 'tight then loose, tight then loose' this gets the fluid moving. You should see oil pumping out. If not, wait as it could be an air bubble.3.) Keep checking the master chamber on the lever is topped up with oil4.) Once you feel there are no air bubbles in the system, do the the blled bolt up. Top up the master chamber on the lever. 5.) put the cap back on the master chamber.6.) clean the brake up with Halfords car brake cleaner (if you have halfords out there)7.) bed the brake inHope it helps Edited November 19, 2008 by Nathan Coward Quote Link to comment Share on other sites More sharing options...
