You basically have two main options, Disc Brake or a Hydraulic rim brake (Magura)
For a rim Brake you will need a frame with Magura mounts welded to the frame (Alot of Muni frames already have these) they will look like this
If the frame has these mounts then all you need to do is get a Magura brake, some Magura clamps and a brake lever mount and you have everything you need. Here at Unicycle.com UK we have a Starter brake kit which contains all you need to get riding with a brake.
For a Disc brake setup there are two paths you can take, Internal or external.
For this option you will need a Disc Hub* (such as the Nimbus Oracle Disc Hub), Nimbus D’brake (if your frame does not have a disc brake tab), Brake lever mount and a Disc brake.

For this option you will need a pair of disc compatible cranks (such as the Kris Holm Dual hole Spirit Cranks), Nimbus D’Brake (if your frame does not have a disc brake tab, a few washers may be required), Brake lever mount and a Disc brake.
