Ferodo brakes are developed to excel in the four phases of braking.
Phase 1 – Initial Bite
This is how quickly the brakes reach their operating torque. A racer wants to feel the brakes “bite” instantaneously when pulling the lever.
Phase 2- Straight-line Deceleration
Most of the deceleration needs to be made when the motorcycle is travelling in a straight line when tyre grip is at a maximum. In this phase the rider wants the highest possible brake efficiency (deceleration for a given lever pressure.) The brake pad’s coefficient of friction (µ) represents this efficiency. The higher the co-efficient of friction of the pad, the lower the lever force required to decelerate.
Phase 3 – Modulation Phase
µ can be affected by a number of factors including disc temperatures, brake disc rubbing speeds and clamping forces. Ferodo develops their brake pads to provide consistency during these changing operating conditions.
This is key to the brakes performing well in the final phase of braking, when disc temperatures increase and rubbing speeds reduce. This is known as the modulation phase. A pad with good modulation maintains a linear relationship between lever pressure and deceleration, which means the brake is more “predictable.”
This is extremely important as the tyres will often have reduced longitudinal grip (as the bike turns) – and so be easier to lock – during this final phase.
Phase 4 – Release
At the end of the braking event, when lever pressure is released, it is important that the brake pads release instantaneously from the disc and then cause low residual brake drag. When the brakes are not being used it’s very important that pad-disc contact is at a minimum. This keeps drag at a minimum and hence speed at a maximum. Ferodo brakes are designed to achieve this.
Over 90-plus years of racing we have learned how to measure these four phases objectively and effectively. Ferodo only release parts to market that perform exceptionally in all four of the braking phases.
