    Swapping brake sides

    This is my first stupid question! I have a set of Magura Julie disc on my bike at present. Love the brakes, but the front is on the left, which i dont like. I have tried for a while to get used to it, but think it is time to swap. I have read the procedure for swapping hoses, and it seems relatively easy, but I am just about to hop on a plane, and dont have time right now, today to do the swap, and I am straight on my bike out of the airport. I have just swapped the levers round, and mounted them upside down on the bar. Does anyone know if this is likely to cause any problem, at least until I have time to sort it out properly?
    Thanks.

    I can't think of any reason it would make a difference aside from cosmetic. If it rolls, RIDE IT MOTO STYLE!

    Actually, some brakes don't like it when you flip the master cylinder/lever. You'll have to check the manual on the Maguras specifically.

    If that's true then some engineer somehwere needs to get the smack upside the head.

    It is true. Some engineers do need to be smacked. My XTRs can not be swapped as the reservoir has to be on top.

    ah but the ones that can't be flipped can be made so that you don't have to rotate them when bleeding. there's probably other benefits and limitations i don't know about besides screwing over the customer

    I cant find anything in the user manual that says the reservoir needs to be on top, so i will see how it goes for a couple of days until I can swap the hoses.

    nope can't swap the levers from one side to the other. you have to swap the hoses in the levers and rebleed the brakes.

    You will be fine for the short time your on your trip. When you come back you will have to swap long term. If you cant swap while away, at least rotate them around overnight at least.

    - Air is less dense than brake fluid it will try to go to the highest point
    - When you squeeze your brake, you pump a small amount of fluid from the MC into the reservoir
    - When you release, you pull a small amount of fluid from the reservoir into the master cylinder
    - If your master cylinder is on top, this cycling will result in air entering your MC

    ok - i am suitably convinced, and i have changed them back. Guess i will just find time to do the swap properly! Thanks for all your replies.
