    i would really need a brake for my "muni" (my trials that i use for
    muniing)
    i have no access to a welder and there is nothing to mount the brakes to
    already (i will worry where to attach the brake lever later :))
    and do i need special brakes or could a purchase one from any bike
    shop?

    please any info will do



    P.S i have a 2.5" wheel

    You either use some dodgy thing that clips on with hose clips, or you
    find a bike shop that will weld brake mounts on. A lot of them will and
    it doesn't cost insane money.

    The kind of brakes most people get are Magura HS33 hydraulic brakes.
    They cost quite a lot. If you're getting brake mounts welded on, you
    need special Magura specific brake mounts welding on to put these on.
    Some bike shops will be able to get these, usually ones that deal with
    trials bikes.

    You can also use v-brakes, like on a normal bike. These need normal
    brake mounts welding on, loads of bike shops will be able to organise
    this. V-brakes start pretty cheap. There are supposedly some
    disadvantages compared to maguras, although I don't know how many people
    have actually tested V-Brakes to see what the disadvantages are in
    practice.

    Vs or Hydros are the best but if you don't need huge amounts of braking
    then you could get away with a caliper brake.

    Something like this:

    The cable might rub your leg a bit. You will need a pretty big one to
    fit around a unicycle wheel, a BMX one should do it.

    To fit it all you need is a hole drilled in the middle of the crown (at
    the bottom of the tube the seatpost fits in)

    I don't think it's power that is the problem as pretty much any brake
    can lock up a wheel. The modulation on maguras is very good which I
    think is one of the main things people say is better about them.

    It'd be interesting to see how well a bmx caliper brake worked, it'd be
    a very neat solution without the hassles of hydraulic brakes.

    I've heard from several people that brakes other than maguras are bad
    because you could knock them into the wheel, but not heard this from
    anyone who's actually used anything other than maguras?

    I had centre pulls on my 26". These never got knocked but the tyre
    clearance was pretty poor. Only good for a 2". I also had some cable
    V's on my 24x3. These would knock into the rim occasionally but it
    didn't affect riding noticably.

    If you want to do a V-brake, then you can use this:
    http://www.unicycle.com/shopping/shopexd.asp?id=566
    And Im pretty sure you dont need to weld it on. Just buy that plate, the
    v-brake, and put the v-brake on those posts, and then figure out a way
    to attach that to the frame right above the tire so the brake pads are
    touching the rim. Make sure it is firmly attached to the frame.

    At least i think thats how its done, I have never done it or heard of
    anyone doing it. So anyone, please correct me if im wrong.

    Ahh yes, it says that -"Mount your V-brake without welding or drilling
    your frame!"- and -"Mounts easily with two two standard
    industrial-strength automobile hose clamps, included."- to confirm what
    I said.

    So this seems like the easiest and cheapest way to get brakes on your
    unicycle.
