    Shimano lever flip

    Hmm you know I want to flip the hoses on a Shimano brake to change the front and rear controls .
    I have one question can I do the job without bleeding? I mean to take the lines out of the levers neat and set each in the other lever without fluid loss either from the hose or the lever?
    You know im in lack of Mineral oil right now and I need to do the job!!

    Oh by the way another thing I use Shimano’s mineral fluid . I want to know can I use it in other brands which use minerals?? Like Magura—Tektro or I have to use their own fluid in each??

    If people cut the hose shorter and replace it without a bleed (done very often) then it shouldn't be a problem to just switch the lines

    If you keep the cap on the lever no fluid should leak out.

    Squeeze the lever to pump out the piston before you disconnect the hoses. Swap the hoses (you SHOULD use a new compression olive and barb fitting). Tighten up the fittings. Reset the pistons. Remove the reservoir cover and diaphragm and top off the fluid.

    If it tightened up and isn't leaking it may be okay. It is best to use new fittings. The fittings are supposed to deform to make a seal. Obviously it can't do that as well if it has already been deformed.

    Magura Blood mineral oil = Shimano mineral oil, but 1/10th the cost or something. Easy to buy in larger quantities and keep a perfect bleed at all times.

    You're supposed to replace the fittings with Hayes and Avid brakes too... They're all made of brass. And they are meant to deform to make a seal.

    Magura mineral oil and Shimano mineral oil are different viscosities. I have seen them mixed or used in the other system though. It seemed to work fine.
