Hydraulic Friction
This lever brake uses hydraulic fluid to transmit force from the brake lever to the brake pads. When the rider pulls the brake lever, the hydraulic fluid inside the lever body compresses a little. This tiny compression creates pressure in the fluid that pushes out pistons in the brake caliper. The pistons move the brake pads closer together to grip the brake rotor. The hydraulic system magnifies even a small pull on the lever into strong pad-to-rotor friction. Hydraulic friction is very common on high-performance bikes because it allows precise control over braking strength. Riders can adjust the lever feel and pad clearance to suit their needs. The consistent and adjustable friction makes hydraulic lever brakes great for racing or hilly terrain.
Cable Friction
In this type of lever brake, the rider pulls a cable when they pull the brake lever. The tensioned cable then moves the brake pads inboard to meet the brake rotor. Cable friction is simple and lightweight compared to hydraulic systems. All the components - lever, cable, and brake - are usually mechanical without hydraulic fluid or pistons. This simplicity makes cable friction easy to maintain and repair. Riders can troubleshoot any issues with basic tools. Many entry-level bikes come with cable friction brakes because they perform reliably under varied conditions. While they may lack the power and precision of hydraulics, cable friction lever brakes get the job done. Commuters, casual riders, and mountain bikers appreciate the adequate stopping strength and ruggedness of cable friction brakes.
Mechanical Friction
Like hydraulic friction, mechanical lever brakes use levers and linkages to amplify the rider's input. However, mechanical systems rely on springs, levers, and other mechanical components, not hydraulic fluid. This makes mechanical friction simple to operate and maintain. Riders can adjust the brake feel and pad clearance using basic tools. Many commuter and urban bikes opt for mechanical friction for its reliability and ease of customization. While they may lack the precise control of hydraulics, mechanical systems provide adequate stopping power with adjustable friction. Commuters, casual riders, and mountain bikers appreciate the ruggedness of mechanical friction brakes.
In general, the specifications of the leva freno will depend on its intended use and the vehicle design. Here are some common specifications:
Material
The handle and the lever arm of the handbrake are usually made of materials such as plastic, aluminum, or steel. The material will affect the strength, weight, and appearance of the handbrake.
Size
The length of the lever arm and the size of the handle will affect the force required to pull the handbrake and the space it takes up in the vehicle. The dimensions should be suitable for the intended use and ergonomic considerations.
Force exerted
The force exerted by the handbrake on the brake pads or discs should be sufficient to hold the vehicle stationary on slopes and prevent rolling. However, the force should not be excessive to avoid damaging the braking system components.
Adjustability
Features such as lever length or handle position adjustment may be considered. This will allow the handbrake to be adapted to different drivers' preferences and accommodate different vehicle loads and inclines.
Stopper design
The handbrake has a stopper or lock mechanism to keep it in the down position when not in use. The stopper should be reliable and easy to engage/disengage.
Indicator light
Some vehicles have a handbrake indicator light on the dashboard to notify the driver when the handbrake is engaged. This is especially important to prevent driving with the handbrake pulled, which can damage the braking system.
To ensure proper operation and safety, the handbrake should be maintained regularly. Below are some maintenance requirements:
Handbrake lever
The tension of the handbrake lever should be checked periodically. If the tension is too loose, the vehicle may roll. If it is too tight, it may strain the brake cables.
Brake cables
The handbrake usually uses brake cables to connect the lever to the brake pads or discs. These cables should be inspected for wear, damage, and fraying. If any problems are found, the cables should be replaced. The cables should also be lubricated periodically to ensure smooth operation.
Brake pads
The handbrake uses brake pads or shoes to create friction with the brake discs. These pads/shoes should be inspected for wear and replaced if necessary. Worn pads/shoes will reduce the handbrake's effectiveness.
Adjustment
The handbrake may need adjustment periodically to maintain its tension and effectiveness. The adjustment procedure may vary depending on the vehicle design. The vehicle's service manual should be referred to for the correct method.
Cleaning
Dust, dirt, and debris should be removed from the handbrake lever, handle, and surrounding area. A damp cloth or mild detergent can be used for cleaning.
Choosing a proper leva freno can be difficult, especially for retailers who source goods on behalf of clients. Here are some factors to consider to ensure clients get the best value for their money.
