Anyone know anything about disc brakes?

sooooooooooo back to mud dock I went. Mechanic was ever so apologetic, tried to bleed again but confirmed there is a fault. Madison are taking it back under warranty and I am getting a new caliper. Unfortunately I guess this will take some time :( no bici

At least it's not thrown you further down the money hole

Pfffft these things are supposed to be the future

oh hai

i know. it sucks. the front brake is just perfect as well, like really really good

Did they just over tighten the bleed port and crack the caliper?

no idea, mechanic can't seem to work out what the issue is at all

I need to remove and store my Ultegra hydraulic disc levers and brakes. As the frame has internal routing I'm clearly going to have to bleed them before removal.

They'll be stored for a couple of months before being installed on a new frame. Should I reconnect the hoses and store them topped up with fluid, or is it okay to leave them empty?

You don't need to empty them.

Dude just don't bother, best thing you can do is give it a good clean and leave it.

If you have a bike stand, then you can carefully removed the housing vertically without dripping a bit.

You may have to explain. I need to undo the hose to extract it from the frame, can I seal it somehow to do so?

^^ this

You will probably need to bleed them after reassembly on the new frame - that's all.

Nah, just carefully unattach it, removed from frame, and then reattach it to the levers.

You might be lucky and not need bleeding, but if it does, just a simple case of injecting more mineral oil in the system rather than a complete rebleed.

You know how you put your finger at the end of a staw and it hold the water in? The hydraulic kinda like that, but still can drip a bit, hence being careful removing it.

Catching up with thread...

I've got a Magura MT8 that was very nice until I broke the brass(?) pin that links the lever blade to the piston.

Any options other than buying a hideously expensive replacement carbonfibre lever blade kit?

• unbolt the lever from the untapped bars
  
• unbolt the caliper from the frame
  
• bike in stand, horizontal unbolt hose from caliper. As soon as hose is released point it upwards so it can't drip.
  
• remove caliper (you can cap it off with the right sized screw if you want)
  
• position bike vertically with hose facing up
  
• draw hose through the frame and out
  
  

It's all about using gravity to keep the fluid where it needs to be. There's surprisingly little of it in the hose. I suspect there is a bolt out there that would cap it off, too. Have a poke around.

You will need to do a proper bleed on reassembly though - very unlikely you won't get air in the caliper and hose during the process.

Guessing you haven't done this yet, but both the flat-mount road caliper and post-mount mtb caliper would need to use the same diameter pistons for this to work nicely.

MT8? Unlucky. What a surprise - it broke!

Burn with fire. Replace with something that works - XTR, Hope...ANYTHING.

Also - your MT8 might have been recalled - that might be a good option if you haven't exchanged it yet.

Thanks. I won't be reassembling, I'll leave that to someone who has a clue.

Can I do the recall without being the original purchaser?

Was on my polo bike, thought it needed bleeding during a game, so I pumped, then found myself rolling downhill towards a fence... that was a while ago, replaced it with some spare Shimano LX then with an Echo TR trials brake (see posts passim)

Can I do the recall without being the original purchaser?

Dunno. Ask magura or your LBS

Thanks, no I haven't. But if I ever do I'll bear that in mind!

After my troubles with spyre clearances I have bought some BB7 S's (how do you plural a single s? sssssssss.) #ubinscobled
The hope spacer pusher it too far the other way and the spyre's adjustable pad couldn't move enough to cope with it. I'd gotten it to the point where the spokes only rubbed a tiny bit when hooning it but were fine most of the time, but that still aint good enuff.

Would it help if the spacer was thinner than 1mm?

Think you just leave ' at the end instead of 's.
