Overview

The Brembo Brake Fluid Reservoir Kit is a 45ml XL fluid reservoir designed for Brembo RCS Brake Master Cylinders. This smoke-colored reservoir features a 90º tube connector and includes a mounting bracket and hardware. It offers a larger volume compared to smaller 15ml and 30ml racing reservoirs, making it suitable for custom street applications and endurance racing where full use of brake pads is desired without constant fluid top-offs.
Show original supplier description
The Brembo RCS Accessory Reservoir Kit provides an Extra Large 45ml fluid reservoir in a smoke finish, designed specifically for Brembo RCS Brake Master Cylinders. This kit is ideal for custom street applications where the standard 15ml or 30ml racing reservoirs may be insufficient. Endurance race teams utilize the 45ml capacity to ensure full brake pad usage without needing to add fluid to the reservoir during extended use. This kit includes the 45ml smoke fluid reservoir (P/N: 10.4446.63), a mounting bracket (P/N: 10.5733.37), a rubber vibration isolator, reservoir mounting hardware, hose spring clamps (P/N: 01.5386.20), spacing washers, and a clamp bolt. The reservoir is designed with a 6mm tubing fitting size, though Tygon tubing is not included. It is important to note that this brake reservoir kit is designed exclusively for Brembo RCS Brake Master Cylinders and does not fit RCS Clutch Master Cylinders. For clutch applications, a separate Clutch Reservoir Kit (P/N: 110.A263.76) is available. The master cylinder itself is not included with this kit.
