Description

Brake and Clutch Master Cylinders — 0.625, 0.7, 0.75 Bore Sizes

The obp Motorsport range of Compact Master Cylinders is engineered to be the perfect space-saving solution for anyone working with limited room in the engine bay. Produced from forged aluminium, these lightweight designs offer a significant advantage over standard remote master cylinders with their extra-short internal chamber. That’s what makes our compact master cylinders ideal for 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 designed to perform with precision and reliability for clutches and brakes (front and rear).

They’re also a versatile fit for applications in Automotive, Motorsport, Agriculture, and even Hydraulic systems.

Compact Master Cylinders Key Features

  • The compact design maximises space, making this part perfect for tight engine bays.
  • Lightweight construction (weighing just 200g), made from high-strength forged aluminium.
  • The Extra-Short Internal Chamber is optimised for reduced space without compromising performance.
  • The standard 2.25” (57mm) bolt-hole spacing shares the same mounting patterns as most master cylinders on the market, making it a direct fit for many setups.
  • The 60° Mounting Flange provides flexibility in installation angles for various applications.
  • Can be used with remote or attachable fluid reservoirs.

Thread Inlets and Outlets

  • 7/16”-20 UNF Inlet
  • 3/8”-24 UNF Outlet
  • Cut-Off Range – Between 0.7mm – 1.7mm, ensuring precise fluid control for enhanced braking performance.

Ideal for Automotive & Motorsport Applications

When it comes to performance vehicles, the right balance between brake and clutch systems is critical. For motorsport and automotive applications, we recommend the following setup for optimal performance:

  • 0.625” Bore for the front brakes
  • 0.7 Bore for the rear brakes
  • 0.75 Bore for the clutch

This configuration ensures the perfect fluid displacement based on the number of caliper pistons you’re running. For instance, if you’re using 6-pot calipers, you may require a 0.7” or 0.75” master cylinder to move enough brake fluid and deliver optimal braking performance.

Why Choose obp Motorsport?

At obp Motorsport, we’re committed to providing cutting-edge components that deliver both performance and durability. Our Compact Master Cylinders are trusted by professionals across the globe, thanks to our attention to detail, rigorous testing, and commitment to quality.

Upgrade your vehicle with confidence, whether you’re tackling high-speed turns on the track or fine-tuning your off-road setup, obp Motorsport Compact Master Cylinders have got you covered!
