Volkswagen Lingdu first domestic AP9540 four-piston brake!

Lamando is a compact new car that Shanghai Volkswagen launched at the Chengdu Auto Show in August 2014. Shanghai Volkswagen defines Ling Du as "the first wide-body coupe". It is built on the MQB platform and is equipped with the EA888 TSI engine and uses a wet 7-speed dual clutch transmission. Mainly high-end, is a sports compact car, located between Long Yi and Passat.

Ling Du official definition of Ling Du is "Ling Feng crossing" wide body coupe, a clear positioning to make it a part of the young favorite players crush.

        AP Racing Radi-CAL's second-generation series of calipers can be described as long-awaited. Radi-CAL's second-generation series of calipers have been successfully unveiled at the 2016 SEMA retrofit exhibition and have been defined as the second of the classic CP85 series of calipers. Generation 2017 new products.

       At the same time, thanks to the successful launch of the Pro 5000R series of calipers later, AP Racing used the same design concept on the high-performance street version - Radi-CAL, on which basis the new Radi-CAL 2nd generation was born. Series calipers (shown below).

The main advantages of Radi-CAL design concept:

1) Large increase in stiffness - Stiffness increased by 30+% in both static and dynamic conditions, which means better foot feel and longer life.

2) Effective weight reduction - While ensuring high strength, unnecessary parts are removed.

3) Optimized air flow slots - Air flows more efficiently through the calipers, providing superior heat dissipation.

4) Facilitate installation - Asymmetric thickness distribution and internal oil circuit design make it more suitable for compact space.

The second-generation Radi-CAL calipers continue to maintain high-value, high-performance, while taking into account the daily use of added dust cover, anti-shock film and anti-corrosion paint coating. And the second generation caliper compared to Radi-CAL first generation weight reduction of 20%, caliper stiffness increased by 25%, corresponding to about 10% increase in braking force.

The new 95 four-piston series - CP9540, CP9541 and CP9542 can be used with 355-380mm discs, leather CP8530 with CP6600 D55; the new six-piston CP9560, CP9561 and CP9562 can be used with 362-390mm discs, C leather with CP8520 and CP7555 D70. 95 Compared to Radi-CAL, the series of calipers is 20% lighter than the first generation, the caliper stiffness is increased by 25%, and the corresponding braking force is increased by about 10%. The second generation Radi-CAL calipers are also equipped with anti-counterfeiting identification codes. The original manufacturer provides color red, Black and silver options.
