Got a brake which needs shortening? You'll need to get yourself an Olive & Connector to put the brake hose back into your brake lever.

We offer inserts to fit Shimano BH59 and BH90 hydraulic brake hose. Not sure what your hose is? Most Shimano brakes use BH59, but notable exceptions are their 4 piston brakes. Look up your brake model and if you have no luck go for the BH59 version - you tend to be able to make it work on all brakes with a bit of coercion. 

It's worth having a hose clamp to help out with installing the needle, you can grab one here.
