Frequently Asked Questions About Pagid Racing Brake Pads
Q: What does "cold friction" mean for brake pads?
A: Cold friction refers to the brake pad's ability to generate friction and provide effective stopping power when it's at lower temperatures, typically before it has reached its optimal operating range. Pads with good cold friction offer immediate bite from the start, which is crucial for road cars and important for initial braking zones in racing before the brakes are fully up to temperature.
Q: What is "brake fade" and how do Pagid pads prevent it?
A: Brake fade is a reduction in braking effectiveness caused by excessive heat build-up in the brake system. When pads get too hot, their friction materials can break down, or gases can form between the pad and disc, reducing the coefficient of friction. Pagid racing pads are engineered with advanced friction compounds that are highly resistant to heat, allowing them to maintain consistent friction levels even under extreme temperatures, thus preventing fade and ensuring reliable stopping power lap after lap.
Q: What is "modulation" in the context of brake pads?
A: Modulation refers to the driver's ability to precisely control the braking force applied by varying pedal pressure. A pad with good modulation allows for fine adjustments, enabling a driver to smoothly transition from light braking to heavy braking, or to maintain a precise level of braking through a corner. This is vital in racing for maintaining balance, avoiding lock-ups, and optimising corner entry and exit speeds.
Q: How important is "rotor friendliness" for racing pads?
A: Rotor friendliness indicates how abrasive a brake pad compound is towards the brake disc (rotor). While racing pads are designed for performance, some can be very aggressive on rotors, leading to rapid disc wear or cracking. Pagid pads, especially compounds like the RS 4-2-1 Sport, RS 4-4, RS 14, RS 19, and RS 29, are engineered to balance high performance with acceptable or even excellent rotor wear rates, extending the life of expensive racing discs and reducing running costs.
Q: Do Pagid racing pads require a specific "bedding-in" procedure?
A: Yes, most high-performance and racing brake pads, including Pagid's, require a proper bedding-in procedure. This process involves a series of controlled braking applications that gradually bring the pads and rotors up to temperature, allowing for a thin layer of friction material from the pad to transfer evenly onto the rotor surface. This transfer layer is crucial for optimal performance, consistent friction, and reduced noise. The specific procedure can vary slightly by compound, but generally involves a series of progressively harder stops followed by cooling periods. Always refer to Pagid's or your brake system manufacturer's recommendations.
