Olive on Hydraulic Brake Hose

Hi,

Due to replacing a leaking calliper I'm trying to recycle my hydraulic brake hose by removing the old olive and insert. I simply can't shift the olive and am wondering whether I should just buy a new hose and go from there. I could cut the hose but I'm right at my limits for length so really need to get the olive shifted but like I say I can't... has anyone any tips or advice? I've tried putting pliers or a spanner behind it and hammering off but to no effect, I have considered hacksawing it but am worried i'll damage the hose.

    Why can't you just use the old olive and insert with the new caliper?

    Because the olive will be crushed (it's how it seals to the hose) and can't be removed or reused! The insert can be cut out reused.

    I've refitted before when using the same hose. He's not changing hoses. Just screw onto the new caliper.

    Indeed, but he seems to want to remove the Olive and replace it for some reason unexplained.

    :D Don't worry about it, it's brakes and I want to do it properly.

    I've managed to do it now so no drama. I dare say you've done it hundreds of times and you're still alive which is great and you're happy; I've done it properly and I'm happy... everyones happy :lol:
