The CP4400 Compact Master Cylinder is designed with a centre-lock bulkhead fixing (10–22mm), making it ideal for installations in composite structure race cars where space and mounting flexibility are critical.
With inlet and outlet ports positioned at the end of the cylinder, it provides improved clearance for components such as steering racks, making it well suited to tight cockpit and pedal box layouts.
Manufactured from lightweight aluminium alloy and featuring extra short travel to cut-off, it delivers precise and consistent hydraulic performance for race and rally applications.
