How to fix bike brakes?

Answer 1

You might be a little more specific on this one. But, although there are several methods of setting up the cables, the principle for brakes is quite simple. A lever at the handle bar is connected to a wire. The wire has a fixed outer casing and free moving cable. As the lever is pulled, the cable moves also. The outer casing, at the other end of the cable is also fixed, with the cable being able to apply force to a lever near the wheel. This force is then directed, via leverage, onto a pad which is pussed against the wheel rim.

This is a simple enough set up, but there are a couple of points that can be looked at. Firstly, cable stretch, or pad wear can become an issue. Where the cable joins the handle bar lever, there is a nut that can be tightened to lengthen the jacket, therefore shortening the length of available cable. You can also alter this length at the other end (Undo nut, move cable, tighten nut.).

You might also consider replacing your pads (You should adjust your cable after this and use the screw on the side of the lever to move the position of the pads, relative to the rim.

Anything else, you should consult your bike shop, especially discs.
