obp Integral Master Cylinder

<h2>Brake and Clutch Master Cylinders — 0.625″, 0.7″, 0.75″, 0.812″, 0.875″ and 1-inch Bore Sizes</h2> The space-saving, integral design of the obp master cylinder is a game-changer for bulkhead-fit pedal boxes, making it perfect for installations where the cylinder sits conveniently in the engine bay. With the built-in reservoir, you eliminate the need for extra brake lines required in a remote setup, ensuring a leak-free operation and a cleaner, more efficient system. The obp Master Cylinder is designed for compatibility, with a 2.25” (57mm) bolt-hole spacing that matches most standard mounting patterns in the industry. This makes it an ideal choice for a wide variety of applications, including automotive, motorsport, agriculture, hydraulic systems, and more. <h2>Integral Master Cylinders Key Features</h2> <ul> <li>Lightweight at just 350g</li> <li>Vertical Mounting Flange for easy installation</li> <li>3/8”-24 UNF Outlet for reliable connections</li> <li>Standard 84mm Push Rod Length</li> <li>M8 Bolt Hole Size for universal mounting</li> </ul> <h2>Choosing the Right Master Cylinder Bore Size</h2> When selecting the proper master cylinder size for automotive and motorsport applications, a general rule of thumb is: <ul> <li>0.625-inch Bore for front brakes</li> <li>0.700-inch Bore for rear brakes</li> <li>0.750-inch Bore for the clutch</li> <li>0.812″, 0.875-inch or 1-inch</li> </ul> However, this may vary depending on the size of your brake calipers because some calipers require more brake fluid for optimal performance. <ul> <li>Inlet Fitting: 7/16-inch-20 UNF</li> <li>Outlet Fitting: 3/8-inch-24 UNF</li> <li>Push Rod Thread: 5/16-inch</li> <li>Pushrod Length: 84mm</li> <li>Bolt Hole Spacing: 1/4-inch</li> </ul> To add some context, the 3/8”-24 UNF outlet indicates that the outlet port of the master cylinder has a diameter of 3/8 inches, with 24 threads per inch, following the UNF threading standard. This ensures a strong, leak-resistant connection, which is critical in high-pressure applications like braking systems in racing vehicles. <h2>Why Choose obp Motorsport?</h2> When it comes to braking accessories, obp Master Cylinders have earned their reputation as one of the most sought-after options on the market.
