Magura Hs33 2011

[Sponge]

Hey guys,

Though I've ridden before with 2004 HS33s, and only bled it once in its whole lifetime with the help of a friend (yep, sorry I know it's an easy easy job for most! But I've just not been required to bleed it and become fully used to the whole system) , I'm now a wee bit confused about how to get my recently cut down 2011 brake working properly! I've highlighted in bold my main questions so as to make it easier to read and answer.

So I've got a 2011 HS33, and saw the stock hose was waaaay too long even for a rear brake set up, so I flicked through the manual as a double-check to see if there were any particular things to note about this new edition of the brake.

Removed the 8mm barbed nut attached to the hose at the slave cylinder so the whole hose popped off the slave. Then I cut the hose with a stanley, and was instructed to slide over:

1. An 8mm sleeve nut

2. then an olive

^all onto my newly cut hose in that order.

Then required to tighten the nut down into the slave, so essentially I believe the olive was forced into the cylinder with the hose end whilst being tightened down. Note: the 8mm sleeve nut and olive just slide around on the hose when everything's all loose before screwing in. This is how it's supposed to go for the 2004/2005 HS33s too, right?

Now, it seems I get decent and even pad push from the slaves... but, the first 1-2mm pull of the lever feels 'empty' if you get what I mean? I can't remember if it felt like this exactly before any cutting job (and I made sure as much as possible that I didn't lose any oil). Can someone confirm whether or not this is normal of 2011 HS33s? or did I manage to have one or two air bubbles trap themselves in the line?

I am also curious, when inserting the brand new cut length of hose (with 8mm sleeve nut and olive slid on top) into the slave cylinder, does it get pushed deeper into the slave cylinder by the tightening of the 8mm sleeve nut?

Lastly, the fluid that came out was a clear mineral oil, I thought it was water for a second! Did Magura update their oil for 2011 or something? Seems a bit different to the blue Royal blood that's always been about.

I've found no satisfactory answers on the Magura site regarding their 2011 brakes, so I'm hoping you guys can help me out a little with your experience of HS33s! If anyone here already has a 2011 HS11 or HS33, that'd be really helpful!

Thanks very much,

any help would be appreciated

yeah, that's fine, the olive crimps the hose as you tighten the 8mm nut.

Now, it seems I get decent and even pad push from the slaves... but, the first 1-2mm pull of the lever feels 'empty' if you get what I mean? I can't remember if it felt like this exactly before any cutting job (and I made sure as much as possible that I didn't lose any oil). Can someone confirm whether or not this is normal of 2011 HS33s? or did I manage to have one or two air bubbles trap themselves in the line?

Sounds like there was a pocket of air trapped (usually in the lever). If you put the syringe in the lever (but leave the bleed bolt tight in the caliper) and pump the lever blade while twisting the whole lever body around the handlebar, that should get out the last bits of air. The lever should activate the pads instantly.

I am also curious, when inserting the brand new cut length of hose (with 8mm sleeve nut and olive slid on top) into the slave cylinder, does it get pushed deeper into the slave cylinder by the tightening of the 8mm sleeve nut?

no

Lastly, the fluid that came out was a clear mineral oil, I thought it was water for a second! Did Magura update their oil for 2011 or something? Seems a bit different to the blue Royal blood that's always been about.

Yeah, it is quite a light looking fluid, pretty sure it's the same as royal blood, but slightly lighter in colour.
