Try to adjust the cable as described in the manual.
If that doesn't solve the problem try to check the following;
- Is the wheel attached properly, in other words is the brake hub positioned inside the brake? The customer can check and compare the right and left wheel.
- Are the two cable ends (with aluminium end cap) about the same length? If different lengths, the shorter one might have a lose end nipple.
- Is the brake cable still intact?
