Ferodo Brake Bedding-in Procedure:
To achieve optimum performance from Ferodo Racing brake pads please follow the instructions below:
Perform 25 to 30 trial brake applications, each of approximately 4 seconds, using around 50% of normal race pedal pressure. To shorten the procedure applications can be made along the straights as well as through bends.
On completion of trial applications return to the pit lane. Inspect the surface of the brake pads from the two wheels which have been working the hardest. There should be evidence of contact over the full pad area but without glazing. The pads are now ready to race.
Whilst we recommend that pads are inspected, if time does not allow this, assuming procedure (1) has been carried out and a short period of time has elapsed to allow the brake system to cool, the pads will be ready to race.
Important: to optimize the performance and life of both brake pads and discs, during the bedding-in period heat in the braking system should be built up progressively. Pad wear inspection: brake pads must have at least 2mm of friction material. Excessively worn brake pads must be replaced. Thermal paint temperature control. Using this procedure, if none of the 3 paints has changed appearance and the braking performance is not considered satisfactory, it may be necessary to reduce cooling to the discs. If all 3 paints have changed appearance, it may be necessary to increase cooling to the discs.
