Description

This part is a complete front master cylinder assembly used in the braking system of Harley-Davidson motorcycles. It is responsible for generating hydraulic pressure when the rider applies the front brake lever, which is then transferred to the front brake calipers, leading to the application of the brake pads on the front rotor.

Key Features:
Material: The master cylinder is typically made of durable aluminum or high-strength steel, coated with a black finish. This black finish is both aesthetic and functional, offering corrosion resistance while contributing to the bike’s custom or OEM appearance.
Single Disc Setup: The “Single” designation indicates that this master cylinder is designed for use with a single front brake disc (as opposed to a dual disc setup), which is common on certain Harley-Davidson models.
Complete Assembly: The kit includes the master cylinder, the piston, the fluid reservoir, seals, and other necessary components for installation, making it a complete, ready-to-install assembly.
OEM Fitment: As an OEM (Original Equipment Manufacturer) part, the HD45019-96F master cylinder is designed to provide a precise fit for Harley-Davidson motorcycles and maintain factory specifications.

Functionality:
Hydraulic Braking: The master cylinder works by converting the mechanical force from the brake lever into hydraulic pressure. When the rider pulls the brake lever, it activates the piston inside the master cylinder, which then pushes brake fluid through the brake lines to the front brake calipers.
Fluid Reservoir: The assembly includes a built-in brake fluid reservoir, which ensures that the hydraulic system has a sufficient supply of fluid for smooth operation and consistent braking performance.
Pressure Generation: The hydraulic pressure generated by the master cylinder is what forces the brake pads to contact the front rotor, slowing or stopping the motorcycle.

Applications:
Harley-Davidson Touring Models: This front master cylinder assembly is suitable for certain Harley-Davidson Touring models, including those with a single front brake disc (e.g., Road King, Electra Glide, Street Glide).
Harley-Davidson Softail Models: Softail models that utilize a single front brake system, such as the Fat Boy, Heritage Softail, and Breakout, may be compatible with this assembly.
Harley-Davidson Dyna Models: Dyna models such as the Low Rider, Wide Glide, Super Glide, and Fat Bob with single front disc brakes could use this master cylinder assembly.
Harley-Davidson Sportster Models: Some Sportster models, particularly those with a single front brake disc setup, may be compatible with this master cylinder assembly.

Possible Models Compatible with:
Harley-Davidson Touring Models: Electra Glide, Road King, Street Glide (single disc version).
Harley-Davidson Softail Models: Fat Boy, Heritage Softail, Breakout.
Harley-Davidson Dyna Models: Low Rider, Wide Glide, Super Glide, Fat Bob.
Harley-Davidson Sportster Models: Certain models with a single front disc brake.
