OBP Compact Push Type Master Cylinder

OBP Compact Push Type Master Cylinder

The OBP range of Compact Master Cylinders is designed to be the perfect space-saving solution for those working with limited space in the engine bay. Crafted from forged aluminium, these lightweight components offer a significant advantage over standard remote master cylinders, thanks to their extra-short internal chamber. This makes our compact master cylinders ideal for both amateur and professional motorsport, as well as other high-performance applications.

Whether you’re upgrading your braking system or fine-tuning your hydraulic systems, these compact master cylinders are built to deliver precision and reliability for both clutches and brakes (front and rear).

They are also versatile enough for various applications, including automotive, motorsport, agriculture, and hydraulic systems.

Key Features of the Compact Master Cylinders:
– The compact design maximises space, making it perfect for tight engine bays.
– Lightweight construction (weighing just 200g) made from high-strength forged aluminium.
– The extra-short internal chamber is optimised to reduce space without compromising performance.
– Standard 2.25” (57mm) bolt-hole spacing shares the same mounting patterns as most master cylinders on the market, allowing for easy direct fitment in many setups.
– The 60° mounting flange provides flexibility in installation angles for various applications.
– Compatible with remote or attachable fluid reservoirs.

Thread Inlets and Outlets
– Inlet Size: 7/16”-20 UNF
– Outlet Size: 3/8”-24 UNF
– Cut-Off Range: A finely-tuned range of 0.7 mm to 1.7 mm, which is essential for achieving precise fluid control and enhancing overall braking performance.

Perfect for Automotive and Motorsport Applications
In high-performance vehicles, the balance between brake and clutch systems is of utmost importance for ensuring safety and efficiency. For those engaged in motorsport or other automotive applications, we suggest the following configurations to optimise performance:

– Front Brakes: A bore size of 0.625”, designed for effective heat dissipation and responsiveness.
– Rear Brakes: A bore size of 0.7”, which provides balanced pressure and fluid movement to maintain stability during braking.
– Clutch: A bore size of 0.75”, which facilitates smooth engagement and disengagement for optimal acceleration and control.

This setup is engineered to ensure that fluid displacement is perfectly aligned with the number of caliper pistons in use. For example, if you are equipping your vehicle with 6-pot calipers, it’s advisable to opt for either a 0.7” or 0.75” master cylinder. This will ensure that enough brake fluid is moved, thereby delivering superior braking performance under various driving conditions.
