DescriptionThe whole story▼

When lap times matter and every braking point is a negotiation between confidence and physics, the Brembo GP4-RX CNC 2-piece radial brake caliper kit at 108mm bolt pitch delivers the precision and stopping power that define the GP4 lineage — now road-legal with TÜV and KBA approval. Engineered for supersport machines that demand more than OEM hardware, this kit brings genuine race-derived braking to circuits and public roads alike.

Key Features

  • CNC-machined 2-piece bolted caliper body in nickel finish — maximum rigidity, reduced flex under repeated hard braking, and outstanding thermal dissipation
  • 4-piston design with 32 mm pistons featuring double sealing, optimised for road use without sacrificing track-level modulation and feel
  • TÜV and KBA approval — factory-certified for road use across a wide range of supersport models, removing the guesswork from homologation
  • Compatible with brake discs up to 6 mm thick (optimal at 5.5 mm) with an approx. 35 mm friction ring and 30 mm offset — fits original discs on many common platforms
  • Ships complete with high-performance sintered brake pads (07BB3793 Sinter TT), so you can bolt on and ride immediately
  • DOT 4 and DOT 5.1 brake fluid compatible — no system modifications required

Race-Derived, Road-Approved

The GP4-RX is Brembo's answer to riders who refuse compromise. The two-piece bolted aluminium body is milled from solid billet on CNC machining centres, producing a component with tight tolerances and a finish that resists corrosion over long seasons. The nickel surface treatment goes beyond aesthetics — it actively aids heat transfer away from the caliper body during sustained hard use, keeping fluid temperatures lower and maintaining consistent pedal feel whether you are trailing the brake into a hairpin or scrubbing speed on a fast motorway entry ramp.

Modulation, Feel and Confidence

Four 32 mm pistons clamped in a radially-mounted body give the GP4-RX a braking characteristic that is both progressive and immensely powerful. The double-sealed pistons are a deliberate engineering choice that keeps road grime and moisture out of the caliper bore, extending service life and preserving the precise tactile feedback that separates this caliper from lesser alternatives. Combined with the included Sinter TT pads — a compound chosen specifically for high-energy, repeated stops — the result is a system that rewards an aggressive riding style without punishing more conservative daily use.
