Brembo 45ml Brake & Clutch Fluid Reservoir – Transparent, Universal Fit (10444660)

Brembo's genuine 45ml fluid reservoir carries the design integrity and manufacturing precision that made the marque synonymous with race-proven braking. Part number 10444660 is the factory original reservoir — not an aftermarket copy — machined to the exact tolerances Brembo specifies for its master cylinder range, finished in clear-bodied transparency that lets you read the fluid level at a glance without removing a cap or reaching for a torch.

Key Features

• Genuine Brembo OEM part (10444660) — the same reservoir used on factory-spec master cylinders across decades of race and road application.
• Crystal-clear transparent body gives an instant visual check of brake fluid or clutch fluid level from the cockpit, saving time on track walk-throughs and pre-ride checks.
• Chemical-resistant construction stands up to DOT 4 and DOT 5.1 brake fluid without discolouration, crazing or structural degradation over time.
• Universal application: compatible with Brembo brake and clutch master cylinders across a vast range of motorcycles from Aprilia, BMW, Ducati, Honda, Kawasaki, KTM, MV Agusta, Suzuki, Triumph and Yamaha.
• Compact 50 mm height and 50 mm diameter keep the installation footprint minimal on crowded handlebars and clip-ons.

Heritage and Design

Brembo has supplied braking systems to MotoGP, WorldSBK and Formula 1 for over five decades. Every genuine part in their catalogue — including this reservoir — reflects that lineage. The transparent polycarbonate-style housing is not merely functional; it is deliberately styled to complement the clean, purposeful aesthetic of a Brembo master cylinder installation on a high-spec street or track machine. Where aftermarket alternatives can yellow, cloud or crack under prolonged brake fluid exposure, the 10444660 is manufactured to Brembo's own material specification to maintain clarity and structural integrity across years of service.

Performance and Practicality

On track days and race weekends, fluid level monitoring becomes a safety-critical routine. The transparent reservoir eliminates guesswork: a quick scan before leaving the paddock confirms you are operating within the safe range. On road-going machines, the same benefit simplifies regular maintenance checks. The 45 ml capacity is correctly sized for Brembo's radial and axial master cylinder families, maintaining the correct hydraulic volume balance for consistent lever feel and reliable fluid displacement under hard braking or repeated clutch actuation.
