The reason is not inappropriate fixing of the pads. Sometimes, one can experience problems called fading. Fading causes loss of efficiency when brakes are hot. It is the problem connected with the friction material the quality of which is not very good. In order to avoid the problem, it is recommended not to use the brakes excessively. It is better to apply lower gears while going down the steep slopes, using the engine work and not brakes. Unnecessary use of the pads may cause overheating and damaging of brake discs. Another way is fixing pads after scorching (thermal processing) what shall eliminate the fading effect.
