Unfortunately, your question is very unclear. "Sleeve"? Your front brake cable goes through a bolt that goes through the handlebar stem. Are these the parts we are talking about? What part of this assembly is actually broken?
It's probably the cable that goes from the pedal to the parking brake in the back. It's like the brake on a bicycle, it's a metal wire inside of a plastic and metal tube. Sometimes that cable gets split, either from cracking due to age, or getting otherwise damaged. Water and dirt get inside the cable and eventually work through the entire cable.
You buy bicycle brake cables, either from a bicycle store, or from an internet source. If you need to be told this you probably need to be told how to install them as well, so go look at www.bicycletutor.com, www.parktool.com or www.sheldonbrown.com
Cable locks are used for bicycles. They are the proper and the most effective way to keep your bicycle safe. Cable locks can be bought at your local bicycle store.

Really ain't no fixing a brake cable. Replace it with a new cable.
The emergency brake cable is held in place with swivel nuts on each end of the cable. Turn the swivel nuts to the left. The emergency brake cable will come off.
The throttle cable goes from the 'gas' pedal to the carburetor or throttle body to control the speed of the engine. On cars the brake cable goes to the emergency brake, on some motorcycles the brake cable goes to the brakes. (The main brakes for cars and some motorcycles are hydraulically operated, not by a cable.)
The Ford expedition emergency brake cable is held in place with swivel nuts on each end of the cable. Turn the swivel nuts to the left, to remove the cable. Reverse the process to install your new emergency brake cable.
The parking brake has an adjustment bolt on the brake shoe. The parking brake cable has adjustments on each end of the cable.
Parking brake cable? Connect to the cable from the opposite side and the emergency brake cable from the control inside the cab. Self-adjusting cable? Connects to the "star wheel" and the brake shoe return spring inside the drum
