Pad Break-In

Notes On Bedding In The New Brake Pads
In the case of the perforated (holed) friction plate, the contact pattern of newly installed brake pads adapts more quickly to the wear profile of the previously operated brake disc than is the case with smooth brake discs.
In general, the following applies: New brake pads must be broken in (bedding-in period), their optimum braking effect is therefore not reached until after a few hundred kilometers. The slightly reduced braking effect must be compensated for by increased pressure on the brake pedal. The same also applies after a brake disc change.
