3/4 Round Master Cylinder For 2 Wheel Brakes, Polished

OVERVIEW

When it comes to stopping power in your custom off-road machine, precision and reliability are non-negotiable. The Latest Rage 3/4-inch Bore Round Master Cylinder is engineered specifically for high-performance applications where 2-wheel braking is the standard. Whether you are screaming across the dunes in a sand rail or navigating technical trails in a custom tube-chassis buggy, this master cylinder provides the hydraulic leverage needed to bring your vehicle to a controlled halt. The 3/4-inch bore is widely considered the ''''goldilocks'''' size for rear brake setups, offering a perfect balance between pedal pressure and fluid displacement, ensuring your brakes feel firm without requiring excessive physical effort from the driver.

Beyond its mechanical prowess, this master cylinder features a stunning polished finish that elevates the aesthetics of any open-cockpit vehicle. Designed as a high-quality replacement for industry-standard units like those from CNC, Neal, or Latest Rage pedal assemblies, it integrates seamlessly into your existing cockpit configuration. The round reservoir design is compact and efficient, making it ideal for tight mounting locations where space is at a premium. With its 1/8-inch NPT outlet, this unit offers the versatility to adapt to various plumbing styles, whether you are running traditional 3/16-inch SAE lines or modern 10mm metric fittings. At Appletree Auto, we know that your brake system is only as strong as its weakest link, and this polished master cylinder is built to ensure your braking performance is never in question.

FITMENT

This master cylinder is a universal performance component designed for custom air-cooled VW-based vehicles and off-road racers. It is a direct fit for the following applications and assemblies:

• Pedal Assemblies: Direct replacement for CNC, Neal, and Latest Rage hanging or floor-mount pedal clusters.
• Dune Buggies: Ideal for fiberglass-bodied buggies (Manx style) utilizing rear-only braking systems.
• Sand Rails: Standard equipment for long-travel sand rails and desert cars.
• Off-Road Race Cars: Used in various classes where a dedicated master cylinder is required for rear turning brakes or primary rear braking.
• Custom Projects: Any vehicle requiring a 2-1/4 inch on-center vertical mounting pattern for a 2-wheel brake circuit.

PRO TIPS

1. Bench Bleeding is Mandatory

Before you ever bolt this master cylinder into your buggy, you MUST bench bleed it. Air trapped inside the cylinder bore is incredibly difficult to remove once the unit is mounted and the lines are attached. Use a bench bleeding kit to cycle brake fluid from the outlet back into the reservoir while pumping the piston slowly. Continue this process until every single tiny bubble is gone. This ensures that when you finally connect your brake lines, you are only pushing fluid, not air, which results in a much firmer and more responsive pedal right from the start.

2. Selecting the Correct Adapter Fitting

This master cylinder uses a 1/8-inch NPT outlet, which is a tapered pipe thread. Do NOT attempt to thread a standard inverted flare brake line directly into the master cylinder without the proper adapter. You will need a 1/8-inch NPT to 3/16-inch SAE flare adapter or a 10mm Metric adapter, depending on the brake lines you are running. Always use a small amount of thread sealant or Teflon tape on the NPT side of the fitting, but be extremely careful not to let any sealant enter the fluid passage, as it can clog your brake valves or wheel cylinders.

3. Understanding Bore Size Dynamics

The 3/4-inch bore is specifically chosen for 2-wheel brake systems to provide the right amount of hydraulic pressure to your calipers or wheel cylinders. If you find that your brake pedal feels too "hard" and requires too much leg strength, you might consider stepping down to a 5/8-inch bore. Conversely, if the pedal travels too far toward the floor before the brakes engage, you might need a larger bore. However, for 90% of VW-based sand rails and buggies with standard rear disc or drum setups, this 3/4-inch bore unit is the industry standard for a reasonit works perfectly for the weight and mechanical advantage of most VW pedal ratios.
