Brake Spring Compatible with Nissan E20 Front 820 Shoes Pack of 10

A Brake Spring for the Nissan E20, specifically designed for the front 820 shoes, is a crucial component in the drum brake assembly. Here's a detailed description:

Material and Construction
Material: High-tensile steel or a similar durable metal alloy, typically coated with a rust-resistant finish (often zinc-plated or coated with black oxide) to ensure longevity and resistance to corrosion in various environmental conditions.
Shape: The spring is typically a cylindrical coil with consistent, evenly spaced loops that provide the necessary tension when installed. The ends of the coil usually feature hooks or specific bends designed to secure the spring to the brake shoes and the anchor points within the brake drum assembly.
Dimensions
Length: The length of the spring when not under tension might vary slightly, but it is generally designed to fit precisely between the two brake shoes or the designated anchor points within the drum brake assembly. This specific spring for the Nissan E20 would be tailored to the dimensions of the front 820 shoes.
Diameter: The wire used in the spring construction is typically around 2-3 mm in diameter, providing enough strength to handle the forces exerted during braking without deforming.
Coil Diameter: The outer diameter of the coiled spring might range from 10 to 15 mm, depending on the specific design requirements of the brake system.

Functionality
Purpose: The spring plays a critical role in maintaining the correct tension between the brake shoes, ensuring they return to their original position after being pressed against the drum during braking. This ensures consistent braking performance and prevents the brake shoes from dragging against the drum when the brakes are not engaged.
Performance: It must provide sufficient force to return the brake shoes to their resting position but also allow for smooth and responsive movement when the brake pedal is applied.

Installation
Position: This brake spring is installed within the front drum brake assembly of the Nissan E20, specifically designed to work with the 820 shoe set. It typically connects between the two brake shoes or between a brake shoe and an anchor point.
Compatibility: It's designed to be a direct fit for the Nissan E20, ensuring easy installation without the need for modifications. Proper installation is crucial, as incorrect tension or positioning can lead to brake malfunction.

Visual Appearance
Colour: The spring is usually metallic silver, grey, or black, depending on the coating used.
Finish: A smooth, polished surface with no sharp edges or irregularities, ensuring it can slide and move without causing wear on the brake shoes or other components.
This component is essential for the safe and efficient operation of the braking system in the Nissan E20, contributing to the overall performance and reliability of the vehicle.
