BenLeacock™ Posted December 9, 2007 Report Share Posted December 9, 2007 Possibly not bled right or you have still got a split, could also be a mixture of both Quote Link to comment Share on other sites More sharing options...

Because magura oil freezes at a lower freezing point than water that is why they use oil but mine seems to be ok at the minute!?

macy`d Posted December 9, 2007 Report Share Posted December 9, 2007 To be honest you cant really do a quick bleed you have to have the proper bleeding kit to do it all properly, and take your time and just keep bleeding it over and over to make sure you get no air in it. If you have 1 air bubble the brake will not work properly. Quote Link to comment Share on other sites More sharing options...
NicP Posted December 9, 2007 Author Report Share Posted December 9, 2007 thanks alot for all the help shall more than likely if i cant get hold of a proper kit take it to shrewsbury and get them to give it a good old check over and bleedNicP Quote Link to comment Share on other sites More sharing options...

Any pressure created by frozen water would only make the pistons move out a bit. Quote Link to comment Share on other sites More sharing options...
angrybeesound Posted December 10, 2007 Report Share Posted December 10, 2007 In a pinch, if you are using water in your brake, you can use a bucket pretty easily to bleed your brake. I take my lever off so it is easier to work with, but you dont have to do this. With the lever low and the slaves high, I tap the lines to try to get the air moving that way.Keeping the back end high, I stick the lever underwater, pump the lever a couple of times and crack the bleeder on the slave loose, when the lever is all the way in, I close the bleeder on the slave, and open up the lever-which is still underwater. You can repeat this a few times.Moving water from bottom to top is good for not introducing new air while getting rid of present air bubbles, but to flush the whole system you should try something different.With the bucket on a table top, place your lever in the bucket and let the back end hang down and rest on the ground. Crack open the lever bleeder and pump it a few times to get rid of air it may have in it, and then open the slave bleeder. Open it slowly, but then open it all the way and let a lot of water run through. Shut the slave bleeder first.So thats how you bleed your brakes when you are old and senile. Sounds to me like your TPA was all the way in when you/he bled your brake. Try it again with a bucket Quote Link to comment Share on other sites More sharing options...
Clownbike Posted December 12, 2007 Report Share Posted December 12, 2007 To be honest you cant really do a quick bleed you have to have the proper bleeding kit to do it all properly, and take your time and just keep bleeding it over and over to make sure you get no air in it. If you have 1 air bubble the brake will not work properly. I must say i don't totally agree with that, sorry to be a pain.I've bled my brake many times using just a bucket and some water and i think people will agree that it has a very nice feeling to it (responsive and no mushy feeling). The brake will work if it has air in it, it will just feel mushy, i know a guy who actually likes it like that.....strange kid......No need to invest in a bleed kit, just do it in the sink or a bucket. If you struggle there is something in "Wiki" (i think thats the name). If not there are loads of topics on how to bleed a brake. I only posted around 4 days ago telling a guy how to do it.Good luckNeil Quote Link to comment Share on other sites More sharing options...
JonMack Posted December 12, 2007 Report Share Posted December 12, 2007 Bleeding a brake is one of the easiest tasks ever. At first for me it was daunting because I didn't have the correct fluid but when I learnt that it could be done with water the task became so much simpler.I fitted and bled my new RB lever in about 5 minutes last night, fill cup with water, get syringe, fill syringe with water, unscrew bleed bolt on slave, screw in bleed pipe, attach syringe to bleed pipe, unscrew bleed bolt on lever, depress syringe, wait until water comes out of lever, screw in bleed bolt back into lever, remove bleed pipe, screw bleed bolt back into slave, sorted.Took me longer to write that than it actually takes.

angrybeesound Posted December 12, 2007 Report Share Posted December 12, 2007 I just read the wiki article about bleeding using a bucket.
