Bondy Posted February 8, 2009 Report Share Posted February 8, 2009 Hey guys,I'm going to be selling my bike in the next few days and my rear brake needed bleeding (hs33), so i went ahead and used the bath method using waterI've put the brake into water and undid the slave bolt and the bolt on the brake lever itself, i put one finger over the slave bolt hole and then pulled fully down on the lever, then covered the lever hole and released my finger on the slave hole and let the lever go, i did this until no bubbles were left coming out.I put my brake back together, yet the lever is still going all the way back to the handlebar and doesnt feel right, have i done something wrong, or is my brake knackered?any help appreciated, ta!!

Jack Chinnery Posted February 8, 2009 Report Share Posted February 8, 2009 (edited) Was your tpa wound all the way in?Were the bolts done up underwater?What possition were the holding the lever?Did you pull the lever, Take your finger off slave hole then without moving the lever atall did you cover the lever hole the let the lever(blade) retract?

stoozie Posted February 9, 2009 Report Share Posted February 9, 2009 What I meant is the way you spaced it out...Try paragraphing it more. Quote Link to comment Share on other sites More sharing options...
Tim/Trialsin USA Posted February 9, 2009 Report Share Posted February 9, 2009 Even after bleeding god knows how many b'jillions of Maguras in the past 13 years, it still does not come out perfect every time.Here is a hint (not sure it is on the Magura manual or not). If you bled it correctly, more than likely most (if not all) the air causing the problem, is in the lever (master cylinder). To fix this without rebleeding for the 10th time:1. Stand bike up. Flick lever a bunch of times (moves air further toward bleed screw).2. Lay bike down so that brake in questions lever is closest to the ground (lever blade pointing toward ground, bleed bolt pointing toward sky).3. Undo bleed bolt and take it out. If you look down, more than likely the oil it not right up to the top. Pull the lever blade (SLOWLY! lest you want an eyeful of Magura oil) until the oil is forced to the top of the hole.4. Slowly release lever and drip oil in hole (keeping oil level with top). When lever is all the way released (and oil filling hole all the way to top).5. Replace bleed bolt6. Go ride.On really bad days it can take a couple times of this (remember to flick lever in between, helps pull air to the top). I can tell you it is a hell of allot faster than complete re-bleed.*substitute the word oil for water, in your case. Quote Link to comment Share on other sites More sharing options...
Muel Posted February 9, 2009 Report Share Posted February 9, 2009 (edited) Just thought I'd say how I bleed mine. Set the lever blade right out with the TPA wound right out.Set the lever pointing vertically down first.Fill the syringe and tube with fluid, get as much air out as possible.Hang a pot from the bar/lever blade with a tube going into it from the lever bleed bolt, stick some fluid in there so the end of the tube is submerged.Push the fluid through, then pull it back, then push it through, then pull it back. Pump the lever, flick everything, push it through and pull it back several times until no bubbles come out of the tube connected to the lever.Disconnect the syringe. At this point fluid will start to drain down slowly from the lever end, don't worry it's just sucking it in from the pot, this helps as you can screw the bleed bolt back in as the brake is pushing fluid out so you can't get air trapped under it.Take the pot away from the drain tube on the lever, it won't run out because it's secured at the other end. Keep it tipped up a bit anyway.Tip the lever up vertically then put your thumb over the end of the hose, and unscrew the hose, your thumb sealing the end will stop the fluid running out.Make sure the recess for the lever bleed bolt is filled with fluid and is vertical, then screw the bleed bolt in.Then set the lever in to where you want it and wind the TPA in a little bit and set the lever flat or pointing up a bit, then crack the bleed bolt with a rag under it, it should push a little bit of fluid and air out, let it drain for a while with the bleed bolt undone about half a turn, then once it stops flowing the slaves will have hit their stops, so tighten the bolt back up.It's never failed yet, I get results just as good as with a bucket bleed.This might solve your problem, but you never know, bath bleeds are dead easy, so you might have a sealing problem or something...
