You can deglaze the pads by applying the brakes firmly a couple of times at 50-60 mpg. Don't come to a halt, but get back to speed and carry on driving to let the airflow cool them down.
New pads are often a problem too, especially if a different brand, therefore a different friction compound. During use the discs get 'coated' with a very very thin layer of pad compound which helps to assist with adhesive friction between disc and pad. This is the type of friction that slows your car most of the time.
Under aggresive use the greater part of stopping power is down to abrasive friction. It's this abrasive behavious that scrapes clean the pad faces. After the conditioning drive mentioned above the pads will develop a new micro coating of pad material, which improves low speed pedal feel. |
