A cable usually needs to be replaced if there are signs of fraying or kinking and/or braking has been adversely effected. It's worth pointing out that the cable may just need cleaning (see Cable Maintenance). For example, if there is a build up of cack in the cable housing which is preventing the cable from moving freely within it. If it does need cleaning you may feel or hear a grinding when you apply the brakes. The cable housing may also need replacing if it is worn or kinked.

Whatever you do, don't try and interchange brake and gear cables or brake and gear cable housing. Because of the importance of efficient braking DO NOT attempt any maintenance on your brakes unless you are completely confident in your own ability.

1.The brake cable is fastened by the cable clamp which needs undoing with an Allen key and you need to release the brake arms by undoing the retaining clip from the cable housing. Once you've done this, Use a pair of pliers to remove the cable end cap, or you could just cut the cable.

2. Once the cable is loose, squeeze the brake lever and you'll see the barrel on the end of the cable in the retaining clip. If your brake lever has a slot in it you should be able to simply slide the cable out. As you pull the cable out carefully place all the bits of cable housing in order so can put them back properly. Even if you are replacing the cable housing this is a good idea so you know where everything goes.
 

4. Slide the new cable in at the brake lever, and feed it through adding the cable housing at the correct points (Before you feed the cable through the housing it's a good idea to lubricate the insides with a thin lube such as GT-85). Make sure you put all the housing end caps on. Once you've tightened the cable clamp, check the brakes to make sure they are working correctly and make any adjustments as necessary (see Adjusting Brake Levers and Centring V Brakes).

5. Finally, using the cable cutters (don't use pliers for this because you'll just fray the cable) cut the cable leaving a couple of inches and then crimp the cable end cap around the end of the cable using the pliers.
