When consistent stopping power and precise modulation matter most, the Brembo GP4-RB CNC radial brake caliper kit delivers race-bred engineering in a package that rewards both dedicated track day riders and committed circuit racers. Built around a two-piece CNC-machined aluminium body with a 4-piston configuration — 30 mm and 34 mm pistons working in concert — this 108 mm kit offers the kind of progressive, confidence-inspiring braking feel that makes a real difference lap after lap.

Key Features

  • Two-piece CNC-machined aluminium caliper body for a combination of low weight and exceptional structural rigidity under hard braking
  • 4-piston layout (2x 30 mm and 2x 34 mm) distributes brake pressure evenly across the pad face for smooth, precise modulation
  • Dual-sealed pistons engineered specifically for the heat and repetitive stress of race conditions, extending service life under sustained use
  • Anti-vibration spring included to keep brake pads stable and eliminate unwanted pad rattle or vibration
  • Compatible with DOT 4 and DOT 5.1 brake fluid, giving you freedom to use your preferred race-specification fluid
  • Supplied as a complete kit including high-performance sintered brake pads (07BB1973), so you can fit and run straight away

Purpose and Performance

The GP4-RB sits at the heart of Brembo's racing programme, and this kit reflects that pedigree directly. The radial mounting design stiffens the entire braking assembly compared to axial alternatives, reducing flex at the point of load and translating every input from lever to pad with minimal loss. For track day riders who want to make genuine progress, that directness is not just a marginal gain — it changes the way you approach braking markers entirely.

The 108 mm caliper pitch places the mounting bolts at a spacing commonly found on a wide range of supersport and superbike front forks, making this one of the more versatile options in the GP4-RB range. The offset of 22.5 mm and a maximum rotor thickness of 6 mm (optimal 5.5 mm) suit the standard rotor dimensions used on most of the compatible models listed below, reducing the need for additional hardware in many fitments.

This kit is intended exclusively for racing and track use. It is not approved for road use and must not be fitted to road-registered motorcycles.
