Compatible with the YSR X AP Racing Big Brake Kit
Built for high-performance and competition use, AP Racing's Pro 5000 R calipers deliver dependable stopping power without the premium price tag of top-tier race hardware. A forged two-piece aluminium alloy body, AP Racing's Radi-CAL asymmetric architecture, stainless steel pistons and high-temperature sealing all combine to keep braking sharp and consistent when you're pushing hard.
At the heart of the design is AP Racing's Radi-CAL asymmetric layout. By reworking the bridge profile and body shape, the caliper sheds weight while gaining stiffness — so it flexes less under heavy braking loads, and your pedal stays firm and predictable through stop after stop. That rigidity is reinforced by the forged, two-piece bolted construction, which spreads load evenly across the housing, resists distortion under high pressure and keeps the pads making consistent contact with the disc.
Heat management is handled just as carefully. The stainless steel pistons resist transferring heat from the pads into the hydraulic system, helping hold fluid temperatures down and keeping pedal feel stable through long braking cycles, while the high-temperature internal seals are engineered to cope with the thermal extremes of aggressive use — maintaining reliable piston movement and sealing integrity over the long haul. Integrated stainless steel wear plates protect the aluminium body from pad backing-plate contact, preserving the caliper's structure and keeping pad movement smooth.
Mounting rounds out the package. A rigid radial mount holds the caliper in precise alignment with the disc for stable, even braking and consistent pad contact across the disc face.
