AP Racing has announced it is to further expanded its Pro 5000 R range of brake calipers with the introduction of six brand new models. Featuring the Radi-CAL technology, which AP has applied to several of its larger units, the calipers are said to represent the ‘next generation of the popular Pro 5000 range and set the benchmark for value and efficiency’.

The CP9446 is a four-piston caliper suitable for general competition that features a forged two-piece aluminium alloy body and benefits from an asymmetric design concept, which is claimed to offer superior dynamic performance.

Featuring a radial mount with 180x35mm ctrs, the caliper suits discs up to Ø380 x 32/28mm thickness. The smaller bore version, CP9447, is of the same design but is suited for rear applications.

The CP9448 is another four-piston caliper  but is built around a forged, two-piece aluminium alloy body. The CP9448 also incorporates the ‘Radi-CAL’ design philosophy and features a radial mount with 152 x 44mm ctrs, being suitable for brake discs measuring Ø380mm x 32/28mm thickness.

The CP9448 is suitable for front applications, and benefits from a 4lb anti-knockback spring fitted as standard.

AP Racing has also introduced the CP9449, a four-piston caliper suitable for rear brake applications, which features a radial mount of 152 x 44mm ctrs, the caliper suits discs up to Ø380 x 32/28mm thickness. The CP9450 and CP9451 are comparable but utilise different sized pistons.

These latest additions to AP Racing’s Radi-CAL range feature an integral pad retainer that is designed to enhance caliper stiffness, as well as stainless steel pistons and wear plates. A bolted pad retainer with a quick-release spring clip is also supplied.
