The selection of a disk brake pad mostly has a significant impact on the braking power so it is profitable to select a suitable pad and possibly change it according to your own requirements. Pad material: There is a rough difference between sintered or metal pads and such out of organic material like resin or Kevlar). You can generally say that organic pads wear out faster but they also have a higher braking power and tend less to noise development. Supports: Generally steel is used for the supporting plate. But some pads are armed with a supporting plate out of aluminium for weight reduction and a better heat abstraction. Return spring: Everytime you change the pad you should optionally also change the in the brake obstructed return spring. They are generally enclosed to the brake pads. The springs wear out over the years and partially get grinded when the brake pads are strongly worn out. So old springs often can't cleanly loose the pads from the disk anymore. Braking: So that a disk brake can develop its full ability new pads have to be practised in braking first of all. While this process the pads adapt to the surface of the disk, get compressed and friction carbon is generated. Therefor you have to accelerate your bike (aside the traffic) to about 30km/h and then brake speedy. This process you have to repeat about 30 times. Afterwards it is recommendable to brake the brakes individually until they are hot. Best suited for this process is a manageable descent. HINT: Brakes are a security-relevant element!
