Applications: Later XK-150 With Square Pads, Series I E-Type, Later MK I With Disc Brakes and Square Pads, MK II, 3.8, MK X. Dimensions: 47mm x 63mm x 16.5mm thick. Same front/rear on the above applications. Sold per axle set of four pads. Manufactured exclusively for XKs Unlimited, these brake pads were designed and developed in Canada under the highest quality standards: ISO9000, QS9000, VDA6.1 and TS16949 (which incorporates at least four more quality standards than QS9000). Made with riveted backing plates in place to solve a decades-old problem. Sold per axle set. Features and Benefits: ¥ Semi-metallic composite compound ¥ Noise free ¥ Excellent performance and fade resistance ¥ Minimal rotor wear ¥ Friction tested in a state-of-the-art ÒLink Model 3900Ó brake noise dynamometer Ð as used by OEM manufacturers ¥ Manufactured in the same plant where North American OEM friction products are built Manufactured using ÒPositive Molding TechnologyÓ common to most OEM pads but rare in the aftermarket. This press-curing process guarantees precise control of friction-material density. Most aftermarket pads are made via the ÒFlash MoldÓ method which requires high resin content and can lead to fade and increased stopping distances. Positive molding uses high pressure to compress the friction material and bond it to the backing plate. This process ensures consistent friction material density and excellent performance throughout the lifetime of the brake pad.
