With an eye to showing  its impressive list of international race victories, AP Racing will be showing its innovative range of brake and clutch systems, as well as associated products, at January’s Autosport International show in Birmingham. AP Racing can be found on Stand 7610 in Hall 7.

Radi-CAL™ approach

This revolution in brake technology began in 2007 with AP Racing’s patented Radi-CAL™ caliper, and continues into 2014 with the evolution of the concept.

Centre stage will be six separate Radi-CAL™ designs, covering the world of international motorsport. These include calipers specifically for F1, WRC, GT and the WTC. This year AP Racing equipped cars using Radi-CAL™ technology won the Nascar Sprint Cup Series, as well as the Nationwide Series.

In addition, the new World Radi-CAL™ four and six piston calipers and discs for aftermarket road cars will be on display.

Formula One

The first car with AP Racing brakes to win a Grand Prix was a Ferrari 312B driven by Mario Andretti in the 1971 South African GP. For the 2013 F1 season AP Racing supplied nine different designs of caliper and, this year’s F1 caliper and disc technology will be on display.

Braking news

AP Racing has further developed and updated its popular CP5500 Floor Mounted Pedal Box range. Important features such as adjustable travel stops on the throttle and clutch pedals, as well as ball bearing pivots, have been retained but the updated pedal box is available with a new contactless rotary sensor with dual input/output for redundancy, as well as a stronger throttle return spring.

The new Radi-CAL™ R4 brake fluid, with the highest dry boiling point of any racing brake fluid currently available, is at ASI. With outstanding resistance to vapour lock and pedal fade, the new R4 fluid has a boiling point of 340⁰C (644⁰F), ensuring that it’s suitable for the most demanding applications.

Also on display will be AP Racing’s extensive range of Factory Big Brake Kits. Designed as an upgrade to the original factory supplied brakes, these kits focus on the development of high performance components for specific vehicles.

For over 40 years, AP Racing has also been supplying some of the top marques in the high performance vehicle market with brake systems to suit specific applications. Covering both brake discs and calipers, AP Racing supports both high and low volume OE customers, and at this year’s show HSV and Lotus components will be on display.

The Sinusoidal Vane (S-Vane) cast iron discs for Nascar Car, GT and Rally Car applications will be on show. Running between 70-100°C cooler than the old design, the new S Vane disc provides a significant improvement in brake performance, wear rate and reliability.

Offering increased braking efficiency and enhance performance in racing applications, the AP Racing push type dual bore master cylinder improves braking consistency by reducing unwanted low pressure pedal travel and operating at high pressure throughout brake actuation.

Clutch news

AP Racing supplied the majority of clutches in the 2013 Formula 1 championship and has been one of the sport’s leading suppliers since 1967. The 2013 championship winning Ø97mm carbon clutch will be at the show along with a selection of carbon clutches for Rally, GT and single seater applications.

Also on display at ASI will be AP Racing’s 140mm diameter and 184mm diameter ‘I’ Drive Clutch Types. Featuring drive tenons, which locate internal jaws in the lightweight aluminium clutch cover, the ‘I’ Drive Clutch design eradicates the onset of clutch drag. Conventional clutch designs typically feature external ‘jaws’ around the outer edges of the steel intermediate and main pressure plates, which can distort trapping the legs of the aluminium cover and cause the clutch to drag.

With an emphasis on low weight and inertia, coupled with durability & reliability, the AP Racing Ø140mm pull type range of carbon/carbon clutches is available as a twin, triple and four plate unit. The GT variant on display features a 10 Bolt, one piece cover and lugs, and a flat flywheel fixing.
