When you cut a slot or drill a hole in a disc you impact heat transfer. The area around the slot or hole acts as a cool spot when the disc heats up, which is not ideal. Ideally, heat is distributed uniformly around the disc so it can be hit with the cooling air that is pumping through the disc, radiate outwards away from the disc, etc. Cool spots create stress risers and increase the likelihood of the disc cracking. They also cause the face of the disc to distort unevenly, leading to uneven pad deposits, vibration, and judder.

The OEM discs avoid this problem by simply leaving the face blank. While the risk for NVH goes down slightly, so does the pad bite and feel of the disc through the brake pedal. Competitive aftermarket offerings typically have straight slots, which tend to leave cool spots across the disc face between the slots.

During exhaustive R&D testing, AP's J Hook design was found to create a constant pathway of evenly distorted material on the face of the disc. The hooks are spaced out as evenly as possible both around the circumference of the disc, as well as from the inside edge (where the hat attaches) to outer edge, with a slight overlap to promote even heat distribution/distortion. In addition to reducing cracking, the even heating of the disc also helps provide an even transfer layer of pad material on the disc when you bed them in.

Additionally, the J Hook slot pattern produces a greater number of leading edges for the pads to bite into vs. a traditional curved slot pattern, and particularly a plain-faced disc. The benefits include more even heat distribution, less propensity to crack, cleaner pad material transfer during bed-in, and more bite.

About Essex

Essex founder Michael Gue discovered a demand for British road racing cars and parts in the USA, while working in the racing industry in his native country, England. After moving to Essex Connecticut and adopting the town's name for his business in 1981, Essex Racing was established and quickly developed a sizeable and loyal clientele. In the beginning, they thrived as the U.S. importer for Van Diemen and Tiga formula and sports racing cars. But as the demand for Essex's racing cars grew, so did the requests for accompanying spare parts. A separate business was formed to handle this need in 1992, and Essex Parts Services was born. During the following decade, Essex Parts Services became one of the premier suppliers of both road racing and stock car parts in the USA
