    I shortened my shimano XTR hoses.

    The front lever has a short throw and feel firm.

    The rear lever was much much softer and had a longer throw. I pumped it a couple times and now the throw is shorter and feels more firm, but it is not quite the same as the front lever, close, but no the same.

    Did I do something wrong? Should I bleed the rear brake?

    Bit of a bump here, but does anyone have a copy of the original document handy? Shimano's site throws a 404 when I try to hit the PDF link.

    Edit: Disregard, nabbed it from archive.org and attached it here in case anyone else needs it.

    Edit #2: Did this without touching the calipers, and didn't have to bleed. The whole process took about 10 minutes for both cables. Just measure about 12 times before you cut, and make sure you leave enough room for the bars to turn lock to lock cleanly.

    Didn't have to bleed or crack the reservoir - just a few pumps with the lever and they're perfect. Thanks for all the tips in this thread!

    Thanks for posting that document! Installed a set of SLX on my wife's bike this afternoon.

    If anyone wants an alternative the shimano bleed kit, go to tractor supply company and buy a 49 syringe and 1/8" fuel line. Does the trick for a fraction of the cost.

    Shortened both new XTR hoses, super easy and intuitive. I pulled the pads and pumped out the pistons a few times to fill the caliper with more fluid. A good idea, it made for a firm lever...

    Were you able to thread into the caliper and master cylinder?

    Not the master cylinder. They shimano funnel is only to catch the over flow. If you don't mind spilling some liquid gold, there is no need for it. I'll probably buy one for future use, but no need to spend they additional $20 on the syringe. The syringe only slides over bleed nipple. No threading involved.

    Worked like a charm, saving the pdf to my hard drive. I used an exacto knife to cut the hose and I think the cut was much smoother and event than when I have cut cables with cable cutters. I don't have a vice so I used Vice grips to clamp the yellow blocks and the hose and held it against something for resistance while hammering that insert into the hose. No leaks and no bleeding needed.

    On a related note, my ice tech rotor did not come with the fixing washer. I called Jenson and they said that Shimano no longer uses the fixing washer but they haven't update their instructions. They claim that a lot of customers have called them about it...

    I used the Vice Grip widget too and it worked like a charm.

    Quick question before I attempt this on my XT's...
    Does all of the fluid leak out the opening, when the hose is removed from the lever? Or is it similar to my Stealth Reverb post, with a ball valve type of assembly that closes when the contact is opened?

    I just did it last week on Deores and there was 2-3 drops of fluid after I disconnected the hose that dripped once I accidentally moved the lever. I don't know what kind of valve is in the lever, but fluid does not leak out.

    As cjsb stated, you will only get a few drops out. That is, assuming you DON'T pull the brake lever. Note that any fluid coming out is being displaced with air and it's this air that we bleed off after re-assembly. The more fluid loss, the more air introduced.

    I also just did this with my deore's and there was no noticeable loss from the master but I was very careful not to bump it or touch the lever. I did bump the line which made a few drops come out but I'm hoping that didn't matter since it was before I cut the line.

    The reason you pump the pistons out before cutting the line is because your are forcing that fluid back in to the reservoir after the line is reattached. A drop or three if loss won't matter.

    Shortened new XT brakes last night and couldn't believe how easy it was. Thanks to everyone for their additional comments to enhance the instructions. Excited to be done with Elixir 3 brakes... they were truly awful.

    I am just looking to reroute my brake line through my frame. Will it leak fluid if I disconnect the line form the lever (step 3 in the PDF)?

    When I did mine I had 2-3 drops come out well after I removed the line when I accidentally bumped the lever.

    So assuming I don't touch the lever I should be good? Either way I will wait until after I ride tomorrow to mess with it.

    You're going to get some minor fluid loss through the open brake line, but that's to be expected. You might have to do a quick bottom up bleed, but if done by expanding brake pucks first, you should be fine without having to bleed. You can find that process here on MTBR. My assumption is that you're disconnecting the line from the master cylinder?

    just follow the instructions in that document and it should be fine.

After seeing just how easy it looked in the video I said "screw it" lets do it.

    Super easy.

    Just finished trimming my slx hoses. Followed the pdf that seventh-777 posted. Worked like a charm! I did have to crack the front reservoir to let some air out. But the back one was fine and that was not needed.

    Just did my XT's tonight. The original link was bad and didn't see the updated link until now.

    For anyone wondering if you can do this... I did front & rear in a hotel room. No stand, no vise, no vise grips. With the calipers on the bike (pads out)

    Just some Allen wrenches, tire levers, small Channel Locks, Crescent wrench and a utility knife with a fresh blade (simply cut the hose while it was laid horizontal on a table).

    Still need to pop the reservoir cap on the front brake, it's really stiff/firm.

    Followed similar (same?) procedure.
