Product Description

HBS-Z-002 Motorcycle Brake Assembly 15.8mm or 19mm Hand Brake Master Cylinder Pump for Racing Motorcycles

The HBS-Z-002 OEM Motorcycle Brake Assembly operates by translating hand lever pressure into hydraulic force, which moves brake fluid to the front brake caliper, enabling smooth and responsive stopping for riders. Its application spans street motorcycles, off-road bikes, electric motorcycles, dual sport models, scooters, cruisers, touring bikes, and three-wheeled vehicles—performing reliably in daily commutes, off-road adventures, and racing scenarios alike. This motorcycle brake pump is tailored for racing motorcycles and all listed applicable models, featuring a 22mm handlebar fit, 9mm piston stroke, and optional 15.8mm/19mm bore diameters to match diverse performance needs.

Our B2B solutions also include bulk OEM Motorcycle Brake Assembly supply, OEM HBS-Z-002 brake assembly customization, and wholesale motorcycle brake pump distribution—aligned with your business goals, backed by a one-year warranty and durable aluminum alloy construction.

Related Questions

1. What are the common faults of a brake master cylinder?

You’ll notice that the fluid level in the reservoir is low or empty, and that topping up the fluid isn’t a long-term solution. Brake pedal sinks or feels spongy: A spongy or soft brake pedal can be caused by a leak in the system, and it can cause your brakes to fail.

2.Key features and benefits of the radial master cylinder

Direct force application: The lever push is transmitted directly to the master cylinder piston, which is mounted perpendicular to the handlebar.
Improved brake feel: This direct transfer reduces lost force and friction, resulting in a more precise and linear braking feel, allowing for better control and modulation.
Enhanced performance: Radial master cylinders deliver a stronger and more instantaneous braking response, as they don’t have to redirect the lever’s force.
Rigidity and precision: They are often made from better materials and with a superior design, providing more rigidity and accuracy.
Safety and confidence: The improved feel and control can lead to greater confidence and safety for the rider.

3.What is the difference between axial and radial brake master cylinder?

In an axial master cylinder, the master cylinder’s bore runs at a right angle to the direction in which the lever is pulled. A radial set-up (pictured) moves the piston parallel to the lever. The key advantage of a radial design is that it requires less force for the same braking effect.

4.What is a motorcycle rear wheel brake master cylinder?

A motorcycle rear master cylinder is the “heart” of the rear hydraulic braking system, converting the mechanical force from the brake pedal into hydraulic pressure that forces fluid to the rear brake caliper. These units are typically made of durable materials like aluminum alloy and are available in universal or vehicle-specific designs, requiring proper size and compatibility checks before installation.

5.What is a radial master cylinder?

A radial master cylinder is a brake component where the piston pushes directly out perpendicular to the handlebar, providing a more direct and linear force transfer from the lever to the brake system. This design provides improved brake feel and modulation compared to an axial master cylinder, which applies force at a 90-degree angle. Radial master cylinders can increase braking confidence and control, especially for performance-oriented applications.
