Product Description

15.8mm or 19mm HBS-Z-005 Right Hand Brake Master Cylinder Hand Brake Pump for Racing Motorcycle

The HBS-Z-005 master cylinder front operates by transferring hydraulic pressure when the hand lever is engaged, pushing brake fluid to the front caliper and activating the braking mechanism for precise control. Its application spans street motorcycles, off-road bikes, dual sport models, electric motorcycles, scooters, cruisers, touring bikes, and three-wheeled vehicles—delivering reliable performance across urban commutes, off-road trails, and racing scenarios. This hand brake pump fits all racing motorcycle variants and the full range of listed applicable models, with 22mm handlebar compatibility and 9mm piston stroke for consistent operation.

We support B2B partners with factory-direct pricing and a low minimum order quantity. For custom brake component development, our engineering team can assist with tailored solutions.

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.What is the operating principle of the master cylinder?

The master cylinder, also known as the master brake cylinder, converts the pressure on the brake pedal to hydraulic pressure by feeding brake fluid into the brake circuit and controlling this according to the mechanical force.

3.How does a motorcycle brake master cylinder work?

When you press the brake lever, the master cylinder pump pushes the brake fluid through the brake hoses to the calipers. In turn, this pressure pushes on the caliper’s pistons which have brake pads attached to them. The pads are compressed on to the brake disc.

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.
