OBP Street Series SSO 4 Pot Brake Callipers

The OBP Street Series SSO 4 Pot Brake Calipers are built to deliver controlled, consistent braking for both daily road use and high-demand driving. With four-piston operation and a lightweight forged aluminium body, they re designed to give you better pedal feedback, increased stability under load, and efficient heat management. Whether you re navigating stop-start traffic or dealing with repeated high-speed braking, these calipers are engineered to maintain braking performance and feel without unnecessary compromise.Here are the key technical features and how they impact performance:Split Forged 6068-T6 Aluminium Construction: Manufactured using advanced split forging and CNC machining, this construction method increases structural integrity while reducing weight, resulting in improved heat resistance and a more responsive pedal feel during both daily use and intense braking.Four Aluminium Pistons (38mm and 41mm): The dual-size piston layout offers a 45.34cm² total piston area, distributing braking pressure evenly across the pads, which helps reduce pad taper, maintains consistent braking force, and supports better modulation and control under pressure.High-Temperature Black Brake Paint: The calipers are coated in a heat-resistant black finish that protects against corrosion and surface wear over time, helping to maintain appearance and integrity even in environments exposed to frequent high temperatures from repeated braking.Compact Dimensions and Compatibility: Sized at 275.7x83x138mm and weighing 5.6kg per pair, the calipers are designed to fit 15" and 16" rims and suit 286 296 x 24mm discs, ensuring practical integration into a wide range of vehicle setups without compromising clearance or fitment.AP9440/AP5200 Brake Pad Compatibility: These calipers accept commonly used AP9440 and AP5200 pad shapes, allowing straightforward access to a range of pad compounds, which supports easy servicing and tuning for different driving conditions.M10x1 Fluid Port Design: Built with an M10x1 threaded port, the calipers offer a reliable hydraulic connection that s compatible with a range of standard fittings, making installation easier and reducing the need for custom adaptors or modifications.2-Year Warranty Coverage: Supplied with a two-year warranty, the calipers are backed for long-term performance, giving you added reassurance when integrating them into your braking system.Fitted to the right setup, these calipers help you achieve more predictable braking behaviour, reduced fade in repeated use, and better overall control in demanding conditions. They're a valuable addition to your vehicle setup if you re looking to enhance braking performance without losing practicality for everyday use. With their technical construction and compatibility with widely used pads and discs, they serve as a smart choice for anyone upgrading or refreshing their brake system.2 Years manufacturer's warrantySold as a pairOBP Street Series SSO 4 Pot Brake Caliper Product Information Sheet
