OBP Street Series SS 4 Pot Brake Calipers - Pair

The OBP Street Series SS 4 Pot Brake Calipers are designed to enhance braking stability and control across a wide range of driving conditions, including daily commutes, fast road use, and track sessions. With a focus on delivering consistent pedal feel and improved thermal efficiency, these callipers support better braking performance when it's most needed. Precision-built from 6068-T6 aluminium alloy using split forging and CNC machining, they offer a combination of strength, reduced weight, and heat resistance suited to high-demand environments. Their 4-piston layout provides even pad pressure, contributing to dependable braking response without compromising drivability.

Here are the key features of these brake callipers:

• 6068-T6 Aluminium Alloy Construction: Manufactured using CNC-machined 6068-T6 aluminium alloy, this material offers high strength-to-weight ratio and corrosion resistance, providing durable performance in variable driving environments while reducing unsprung mass for improved handling and suspension response.
• Split Forged Design: The calipers use a split forging process that enhances structural integrity and reduces unnecessary material bulk, which contributes to a more rigid and lightweight unit, resulting in better pedal feedback and consistent pressure distribution across the braking surface.
• Black High-Temperature Brake Paint: Finished with a high-temperature resistant black coating, this layer helps protect against heat damage and corrosion over time, maintaining the calipers' appearance and performance in extended high-heat conditions typically found in heavy braking use.
• 56cm² Piston Area (38x41.2mm Pistons): With optimised piston sizing and surface area, the calipers provide balanced clamping force and efficient brake pad engagement, which helps achieve stable and predictable braking performance during repeated stops or high-speed braking.
• Aluminium Pistons: Fitted with lightweight aluminium pistons, these reduce thermal transfer from the pads into the brake fluid, helping maintain consistent braking pressure and reducing the risk of fluid boiling during prolonged use, which is critical for brake system reliability under demanding conditions.
• Compatibility with 330–355 x 28mm Discs: Engineered to fit standard 17 and 18-inch rims, the calipers accommodate widely available disc sizes, making installation straightforward and ensuring consistent part availability for future maintenance or upgrades.
• Common Brake Pad Compatibility: These calipers accept commonly used AP Racing pad shape CP3215 D50, as used in CP9440 and CP5200 caliper ranges, allowing straightforward access to a range of pad compounds, which supports easy servicing and tuning for different driving conditions.
• M10x1 Brake Line Port: Designed with an M10x1 port size, the calipers support easy integration with standard brake line fittings, which simplifies installation and ensures a secure hydraulic connection for reliable fluid transfer during braking.

Fitting these calipers supports more confident braking in both everyday and performance-based scenarios, reducing fade and improving control under pressure. Their lightweight construction and reliable heat management make them well suited for applications where braking consistency is essential. A dependable addition to your vehicle setup, these callipers offer a practical upgrade for drivers looking to improve braking performance without compromising on usability.
