The Pagid RS14 is a popular ceramic based friction material. It has very good modulation characteristics and offers good control against wheel lock at all temperatures. Whilst providing reduced pad wear, particularly at high temperatures it is still relatively light in terms of disc wear and minimises surface stress fractures. Outside the track day environment RS14 has also shown success in circuit racing offering low heat conductivity. The reduced thermal transfer from disc to pad results in lower caliper and brake fluid temperatures.
The Pagid RS15 is a ceramic based formulation developed on the basis of the RS14. Suitable for applications where very high levels of torque are required, or situations were very high disc temperatures are experienced. The increase in bite is often very useful on cars without servo assistance, that are known to require high pedal forces to brake the car efficiently.
RS15 also offers a very high level of cold bite, something that is uncommon with high friction level compounds. This can be beneficial in situations where adequate warm up periods are not possible such as at a race start. Another plus with RS15 is the improvements made with the release characteristics of the material. This allows for much greater levels of control when coming off and going back on the brake pedal, allowing smoother modulation when the brake reacts more quickly to pressure changes made at the brake pedal.
