Running In The Brake Pads And Brake Discs

New brake pads need a running-in time of approx. 200 km (125 miles)! Only then do they achieve their best friction coefficient and wear values. During this time, the brakes should be subjected to full stress when travelling at high speed only in emergencies. The slightly reduced braking effect must be compensated for by increased pressure on the brake pedal. The same applies after replacing or machining brake discs.
