Complete failure...

[_daveR]

...on my part when ever I try to assemble disc brakes! I just cannot do it.

Last night I must have spent 3 hours assembling the XT discs for my new Soda build. - Hoses cut to length
- Inserts fitted correctly
- Hoses fitted to lever and caliper as per instructions
- Bleed front brake, which goes well. Lever fills firm so move onto the rear
- Try to bleed rear and fluid just pisses out of the hose/caliper join!
- Re fit hose into caliper
- Try again... Fluid still pisses out everywhere!

I stop at this point and decide to leave the rear until tonight. So fit the pads to the front caliper and squeeze the lever hard to centre the caliper... fluid fires out from the lever/hose join! ARGH!!

So, to solve my problems... It's gone into the LBS this morning!

Assembling/bleeding disc brakes is the one part of bike maintenance i have yet to have the pleasure of attempting . Judging by your experience, i am not looking forward to it either, and may go the LBS route too.

Those XT brakes are a bit of a bugger, you have to really crank up the compression nut to deform the olive enough. It will feel as if you are over tightening the nut and doing damage but all that is deforming is the crush washer. This needs to happen to create a seal.
Still it could be worse, it could have leaked at the caliper and all over your new pads. That would be a pisser.

From speaking to the shop today that is exactly the problem I had. I was a bit paranoid of doing the threads in but for the sake of £30 the LBS sorted it out, cut my steerer and gave the mechs a tweak too.
