boozeman Posted August 12, 2014 Report Share Posted August 12, 2014 (edited) My zoot had magura hs33 brakes fitted when I bought it. Now I haven't bled it the brakes since I got the bike over a year ago because I don't know how to. Pure lazy I know! Anyways my problem is the fronts don't retract fully when the lever is released. One doesn't even move. Would bleeding them solve the problem or could it be something else. Also the twisty red bit has rounded off inside and doesn't actually adjust anymore. Can I get hold of a metal replacement? Edited August 12, 2014 by boozeman Quote Link to comment Share on other sites More sharing options...
ZArgrave Posted August 12, 2014 Report Share Posted August 12, 2014 if they dont fully go back into the slaves then its because the Tpa (twisty red bit) has been twisted in before it was rounded off and yes im sure there is some metal replacements in one of the for sale threads if not tartys do them too and as far as re bleeding them goes if you havent got a proper bleed kit for them they can be really easily done in your kitchen sink just using a set of allen keys. watch this video its a different model of hs33 but the same applies just the bleed bolt is in a slightly different place Quote Link to comment Share on other sites More sharing options...
bing Posted August 12, 2014 Report Share Posted August 12, 2014 You can't just bath bleed them straight away without flushing all the old oil out of the system first. My advice would be to buy a syringe and bleed pipe from tartys and flush the whole system out using hot water and fairy liquid. Then flush through with clean hot water. Then bleed using cold water and a dab of antifreeze if you want to. As for the tpa, try and get a chorrilas metal job. They work quite well from what I've heard. If you want to lubricate the slaves, pump them out with the lever and get a Teflon based spray and give them a light coating. As for the lever piston, use a bit of spray gun grease, its water resistant Quote Link to comment Share on other sites More sharing options...
jack dickinson Posted August 12, 2014 Report Share Posted August 12, 2014 (edited) As for the tpa, try and get a chorrilas metal job. can totally agree with this.

Can't really see the point of doing this to be honest, I've had brake bled with mineral oil, and all i did before bath bleeding with water was simply take the bleed bolt out and pump the lever a few time until no more come out. Then bath bleed it, and works perfect! Just seems like a slight waste of money. Edited August 12, 2014 by jack dickinson Quote Link to comment Share on other sites More sharing options...
ZArgrave Posted August 12, 2014 Report Share Posted August 12, 2014 i bath bled without flushing the old oil out first and it makes for a very messy sink hah so flushing it first is the clever mans choice Quote Link to comment Share on other sites More sharing options...

Watch what happens. Its like sludge and I wouldn't want that inside my brake. A syringe is a fiver, or free if you can blag one from a chemists. This method has always worked for me, and most people who have rode any of my bikes have commented on how the magura feels. Dan cox, thinkdougie, Adam Baxter, Cocky, Barry clay, Aaron Browne but to name a few. So, again, I'll ignore your opinion as its a load of bollocks. And a 15 year dishing out advice to people who have been riding longer than he's been born is a bit hollow don't you think? 1 Quote Link to comment Share on other sites More sharing options...

You do realise that that oil and water don not mix. so they wont make a sludge, its basic physics. here an explanation from an adult because you don't listen to 15 year olds. Why Mineral Oil & Water Don't Mix | eHow im not saying you are wrong im just saying that buy a whole kit is a bit unessorserry. p.s. wouldn't bath bleeding flush it out anyway? i bath bled without flushing the old oil out first and it makes for a very messy sink hah so flushing it first is the clever mans choice you don't have to do it in the sink. a bucket works fine? although i did have the same problem, a messy sink. but thats nothing a bit a sink brush thing (i found on the side) couldn't wash off Edited August 12, 2014 by jack dickinson Quote Link to comment Share on other sites More sharing options...
ZArgrave Posted August 12, 2014 Report Share Posted August 12, 2014 i feel myself in a strange situation i agree with jack dickinson they dont mix lol i have seen it in my own sink i dont want to live in a world where jacks right so i shall leave this thread ciao Quote Link to comment Share on other sites More sharing options...
jack dickinson Posted August 12, 2014 Report Share Posted August 12, 2014 (edited) and even if you did want to make a flush out, you could simply make a home made bleed kit, using a cross over and water bottle? and when you do that you don't even have to take the brake off the bike ...

boozeman Posted August 12, 2014 Author Report Share Posted August 12, 2014 I've already got a syringe, it came with a avid bleed kit so that's no problem. I think they're water already, but I'm not 100% sure. I'll give it a go one night this week. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted August 12, 2014 Report Share Posted August 12, 2014 Fwiw, fairy liquid emulsifies oil and water combining them together so you're kinda wrong jack x Quote Link to comment Share on other sites More sharing options...

dann2707 Posted August 12, 2014 Report Share Posted August 12, 2014 You're not going to fully flush the system out by pumping the brake. You need to emulsify the oil to get it out hence the requirement of fairy liquid. Quote Link to comment Share on other sites More sharing options...

FamilyBiker Posted August 12, 2014 Report Share Posted August 12, 2014 just to add my totally unnecessary 2 ct,if you use antifreeze you'll have to flush it out first,the antifreeze stuff is most likely glycol based so it will make some kind of foam together with the remaining oil. you dont want foam because its compressable.which means your finger power will go nowhere but into the bubbles (different densities will always feel squishy despite the bubbles not being consisting of air) Quote Link to comment Share on other sites More sharing options...
HippY Posted August 13, 2014 Report Share Posted August 13, 2014 you dont want foam because its compressable.which means your finger power will go nowhere but into the bubbles I felt oddly satisfied and happy after reading this sentence 1 Quote Link to comment Share on other sites More sharing options...
Jake. Posted August 13, 2014 Report Share Posted August 13, 2014 f**k me I didn't realize how in depth water bleeding was. So basically... 1. Bleed brakes with water mixed with fairy liquid. 2. Bleed brakes with water. 3. Bleed brakes with water. 4. Done. Quote Link to comment Share on other sites More sharing options...
bing Posted August 13, 2014 Report Share Posted August 13, 2014 Yes as fairy liquid is a degreasing agent if the TV advert is to believed, so for getting the oil of magura pipes its perfect, and it won't knacker the seals, and it'll keep your skin soft as well.

trialsbikingnunn Posted August 13, 2014 Report Share Posted August 13, 2014 (edited) Not flushing out the system of the old oil that's in there will make it so that you will have to bleed the brake more often. As the oil and water dont mix and the oil sits on top of the water it means that when you pull the brake it will force the water and oil to move about and compress slightly so it wont feel as nice as it would if you had flushed it out, also as said before the removal of oil will help the seals last longer. I must admit I never use the fairy liquid method but that's just because I'm a lazy f**ker and I normally bleed my brakes before a rideso I dont have time to do that method Edited August 13, 2014 by trialsbikingnunn Quote Link to comment Share on other sites More sharing options...

jack dickinson Posted August 13, 2014 Report Share Posted August 13, 2014 just to clarify, i did used to bleed my brake with pure blackcurrent squash, would this have cleared it out?
