DescriptionThe whole story▼
Few names carry the weight of Brembo's P4 30/34 on a pit-lane grid. Machined from solid aluminium billet in Brembo's own CNC facility and assembled as a race-purpose two-piece radial caliper, the P4 30/34 kit at 108 mm pitch represents the Italian manufacturer's heritage of supplying championship-winning teams distilled into a bolt-on package for serious track and racing use. The staggered four-piston layout — 30 mm leading, 34 mm trailing — is a signature Brembo engineering choice that delivers progressive, highly modulated braking force exactly where a rider demands it under hard trail-braking into a corner apex.
Key Features
- Two-piece CNC-machined aluminium caliper body — bolted construction combines rigidity with reduced unsprung weight for faster response at the lever
- Four-piston stagger (2x 30 mm and 2x 34 mm) for even pad-contact pressure, precise bite point and outstanding modulation under race conditions
- Radial mounting at 108 mm centre-to-centre pitch matches factory-spec mounting points on a wide range of supersport and superbike platforms
- Dual-sealed pistons engineered for repeated high-temperature cycling in race environments, resisting fade and fluid bypass
- Anti-vibration spring over the brake pads included, damping harmonic chatter and stabilising pad contact throughout the braking zone
- Complete kit ships with high-performance sintered brake pads (part number 07BB1973), ready to install at the track
- Compatible with DOT 4 and DOT 5.1 brake fluid — no special fluid required alongside the caliper upgrade
Design, Finish and Heritage
The P4 30/34 is one of Brembo's most recognisable caliper silhouettes — the design philosophy has informed decades of MotoGP and World Superbike hardware. The CNC finish is clean, angular and unmistakably purposeful, with the precise machined faces and drilled pad-pin bores that distinguish a genuine Brembo racing component from aftermarket alternatives. Part number 220A01610 is a current Brembo catalogue reference, ensuring you receive an authentic unit with correct tolerances and Brembo's production quality assurance.
The two-piece bolted architecture is not merely a weight-saving measure — it allows the outer and inner halves to flex fractionally under extreme load without introducing the flex that a poorly designed monoblock can mask at the lever. The result is a direct, unfiltered feel that experienced track riders recognise immediately when they first reach for the brakes at the end of a long straight.
Track Performance
Designed exclusively for motorsport and closed-circuit trackday use, the P4 30/34 is not road-type approved and must not be fitted to road-registered vehicles. On circuit it excels — the 108 mm radial pitch and offset of 22.5 mm suit a wide range of production-derived superbike brake disc carriers. The caliper accepts discs up to 6 mm thick (optimal operating thickness 5.5 mm) and is dimensioned for approximately 35 mm friction-ring disc diameters, making it compatible with many OE and aftermarket floating disc assemblies without modification.
