    Best way to cut hydralic brake hose / lines

    I tried doing a search but could not find this subject, although I'm sure it's been discussed...

    I'm installing new JAGUAR brake hose and wondered what the best way is to cut it without damaging it (squishing it).

    In the past I've used double V jawed wire cutters to cut std type brake housing, but I'm afraid this will damage the hose type... or maybe it won't?

    I was thinking I could use a dremel tool with a cutting blade (about 1/32" wide) to cut through it.

    What would be better... a double V cable cutter or my dremel tool with narrow blade?.... or other method? DId I read you can cut this stuff with a razor blade?

    I do not have any other special cutting tools...

    Thx, CJS

    I've cut it with a fresh razor blade. It works fine. Try it on a excess section before cutting it to the desired length.

    +1. I just cut some Formula kevlar hose with a razor blade & it left a nice clean edge.

    I would use a log splitter.

    I just installed some JAGWIRE hoses a few weeks ago and used my standard park cable cutter. There is a screw in fitting that goes into the i.d. of the hose when you insall it to the lever end that will bring it back into shape. If you find that you have flattened it, a nice pointy awl/punch, or maybe even a nail will open it back up.

    i have always used a single edged razor blade against a hard surface.

    actually, you do not even need a hard surface. put slight bending pressure at apex of cut and just carefully slice in mid air. the slight bending will just separate as razor is sliced through

    I've used all three methods with equal amounts of success. My preferred method is a very large pair of cable cutters.

    Anyone tried a Dremel with a cut-off wheel? I've used this on automotive braided hose and it works like a champ.
    Work is the curse of the biking classes.

    The only problem I see with using a dremel is that you could wind up with debris inside of the brake line. I used a razor blade the few times that I have cut brake hose, it leaves a nice clean cut if you are careful about it.

    I've used a Dremel to cut something similar and found that the process generates too much heat that it melts the material, forming clumps. You don't want clumps on your brake hose. I've used a fresh razor blade, as mentioned before, and it works very well.

    I use a razor blade on brake lines. Just hold it taught and cut with one quick, fluid slicing motion. Easy peasy lemon squeezy.

    For cable housing I insert a spare piece of cable into the housing and then cut with a Dremel cut-off wheel. The cable keeps the housing from closing in on itself.

    I've used a razer knife, but you could use anything sharp that will cut clean and not deform the hose.
    I only ride bikes to fill the time when I'm not skiing.

    Sharp razor worked well!

    Thanks for all the input and info, I used a new one edge razor and it worked very well.

    I guess these are plastic hose that are kevlar lined for zero flex or something? The mechanic at the local bike shop will need to be informed of this as he said I'd need cable/wire cutters... maybe he thought I was talking about regular brake cable housing....

    Anyway, all went well, nice blue Jaguar cables on now :-)
