Brembo Rear Axial Brake Master Cylinder Model Ps 11

Brembo 910477601 identifies a rear axial brake master cylinder model PS 11, usually finished in titanium or silver color. This version uses a smaller 11 mm piston, designed to offer a very sensitive, modulable, and precise response on the rear wheel, drastically reducing the risk of unwanted lock-ups.

Born with Racing-derived technologies and made of high-strength cast aluminum alloy, it ensures constant pressure even under prolonged and heavy use.

• Piston Diameter: 11 mm (PS 11 designation).
• Hole Center Distance: 40 mm, the standard interaxial fixing measurement for European-style footpegs.
• Oil Inlet and Outlet: It is equipped with an inlet for the remote reservoir hose and a brake fluid outlet with straight or adjustable fittings depending on the supply variants.
• Weight: Approximately 328 grams.

This model is mainly used as an original replacement or OEM equivalent for BMW Motorrad group motorcycles. The 11 mm configuration is designed to recalibrate the ABS or the single rear caliper or the double piston with a reduced diameter.

It is widely purchased as a universal 'Upgrade' pump for installation on aftermarket racing rearsets (from brands like Bonamici, Lightech, Robby Moto, etc.) on various European and Japanese sports bikes that require an 11 mm command to lighten the rear brake response.
