1. What is an Arm Rear Brake Rocker?
An Arm Rear Brake Rocker, often called a Brake Lever Arm, Torque Rod, or Reaction Arm, is a critical linkage component in a motorcycle's rear drum brake system. It connects the brake pedal/cable to the brake backing plate and is responsible for transferring the rider's braking force into the mechanical action that spreads the brake shoes against the drum, creating stopping power.

2. What is its primary function in the braking system?
It serves two key functions:

Force Transmission: Converts the linear/rotational input from the brake pedal or rod into the specific rotational force needed to activate the brake cam inside the drum.

Reaction Control: Acts as a rigid lever or torque arm, preventing the entire brake backing plate/assembly from rotating when the brake is applied, ensuring all braking force is directed into stopping the wheel.

3. What types of motorcycles use this part?
It is a fundamental component on many motorcycles with rear drum brakes, commonly found on:

Vintage / Classic Motorcycles

Cruisers and Choppers

Scooters and Mopeds

Small-displacement Commuter Bikes

Off-road and Dirt Bikes (especially older models)

Custom-built Motorcycles

4. What materials are your brake rocker arms made from?
We manufacture them from high-strength, durable materials to withstand repeated stress:

Primary Material: High-Grade Carbon Steel (Q235B, 45# Steel) or Alloy Steel (40Cr) for optimum strength-to-weight ratio.

Surface Treatment: Electroplating (Zinc, Chrome) or Powder Coating for corrosion resistance and a clean finish.

Pivot Bushings/Bearings: Bronze bushings or needle roller bearings for smooth, long-lasting operation (depending on model).

5. How do I identify the correct brake rocker for my motorcycle?
Correct identification is crucial for safety and fit. Please provide:

Motorcycle Make, Model, and Year (e.g., Honda CG125 2008).

Clear Photos of the old part from multiple angles.

Key Dimensions (if possible): Overall length, hole-to-hole distance, hole diameters, and the angle of the lever arm.

OEM Part Number (if available). We maintain a large cross-reference database for common models.

6. Are your parts direct replacements for OEM components?
Yes. Our parts are precision-engineered to be direct bolt-on replacements, matching the original OEM specifications for dimensions, hole alignment, and mechanical function. They are designed to integrate seamlessly with your existing brake pedal, rod, and backing plate.

7. Do you offer custom or OEM manufacturing?
Absolutely. We specialize in OEM/ODM services:

Reverse Engineering: From your sample or broken part.

Custom Design & Prototyping: For custom bike builders or new motorcycle models.

Material & Finish Specification: To meet your specific performance or aesthetic requirements.

Private Labeling & Packaging.

8. How do I request a quotation or technical support?
For the fastest and most accurate response, please provide:

Motorcycle model information or OEM part number.

Detailed photos or drawings of the required part.
