The lemonade man Posted October 3, 2006 Report Share Posted October 3, 2006 I recently snapped the crossover on my rear maggy, bought a mini bleed kit, fitted a new crossover and went to bleed it. First I tried in the bath and it seemed fine when off the bike but when I put it on, there was absolutely no power and the lever blade came all the way in with the TPA on full.Then I thought I'd try with the syringe and magura blood, same thing, all went through fine but still no power! There are no leaks or anything and I'm so annoyed I can't ride at the moment so any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
nmt_oli Posted October 3, 2006 Report Share Posted October 3, 2006 (edited) Very odd, heres my bleeding preference for maggies, and has worked very well, others may have other methods.1)Leave the brake on the bike2)Stand bike up, preferably in a workstand of sorts.3)Wind TPA all the way in4)Fill syringe with fluid of choice, and connect to SLAVE CYLINDER, NOT LEVER. make sure there is no air in when you connect it, have fun doign the doctor style squirt. If there is still a bubble point the syringe downwards so it stays in the syringe.5)Connect bleed tube to lever6)Pump away, tap the slaves/lever a couple of time with a spanner or similar to free air bubbles7)Undo bleed tube, replace bolt making sure no air gets in- keep squeezing slightly if nessesary.8)Remove syringe, top up the hole with fluid before replacing bolt9)Wipe upall done.

The lemonade man Posted October 3, 2006 Author Report Share Posted October 3, 2006 To be honest that's the exact guidelines I followed, I'll try once again with a syringe and water and tap it more. Out of interest, how do attatch the pipes to the bleed bolt hole/lever one? I've got a barbed fitting on it but is there a "proper" way to do it?

nmt_oli Posted October 3, 2006 Report Share Posted October 3, 2006 I use a 15cm tube on a syringe, tube has barbed fitting fitted to screw into slave.also a 25cm tube with correct barbed fitting for lever which i route into a conainer to catch the fluid.If your using tap water make sure its setled to get all the air out of it, this is one reason i like using oil, it doesnt dissolve air. the air dissolved in water may come out of solution when in your brake due to changes in pressure/temperature. This will mean you have a spongey brake again. Quote Link to comment Share on other sites More sharing options...
