An accessory kit for brake shoes, also known as a brake hardware kit, includes various components essential for the proper installation, adjustment, and functioning of drum brake systems. These kits are designed to replace worn or damaged hardware and to ensure that the brake shoes operate efficiently and reliably.
Components and Functionality:
1. Return Springs:
- Function: Pull the brake shoes away from the drum when the brake pedal is released.
- Description: Heavy-duty springs that ensure the brake shoes retract properly, preventing drag and ensuring the brakes release fully.
2. Hold-Down Springs and Pins:
- Function: Secure the brake shoes to the backing plate.
- Description: Small springs and pins that hold the brake shoes in place, ensuring they are correctly positioned and do not move excessively during operation.
3. Adjuster Mechanism:
- Function: Maintain the correct distance between the brake shoes and the drum.
- Description: Includes an adjuster screw, star wheel, and lever that automatically or manually adjust the brake shoes as they wear down, ensuring consistent brake performance and pedal feel.
4. Self-Adjuster Springs:
- Function: Help maintain proper adjustment of the brake shoes.
- Description: Springs that work with the adjuster mechanism to ensure the brake shoes remain at the optimal distance from the drum.
5. Guide Plates:
- Function: Ensure smooth movement of the brake shoes.
- Description: Metal plates or clips that guide the brake shoes and reduce friction between the shoes and the backing plate.
6. C-Washers or Retaining Clips:
- Function: Secure various components in place.
- Description: Small metal clips that hold the adjuster mechanism and other parts in the correct position.
Importance of the Accessory Kit:
1. Safety:
- Ensures all components are functioning correctly, which is critical for safe braking performance.
2. Performance:
- Helps maintain proper brake shoe alignment and adjustment, ensuring optimal braking efficiency and response.
3. Longevity:
- Replacing worn or damaged hardware with new components from the accessory kit can extend the life of the brake shoes and other brake system parts.
4. Noise Reduction:
- Properly functioning hardware reduces noise and vibration during braking, leading to a smoother and quieter operation.
Installation and Maintenance Tips:
1. Regular Inspection:
- Periodically check the condition of the brake hardware during routine brake maintenance. Look for signs of wear, corrosion, or damage.
2. Replacement:
- When replacing brake shoes, it is advisable to also replace the hardware kit. This ensures that all components are in optimal condition and can prevent premature wear of the new brake shoes.
3. Correct Installation:
- Ensure all components are installed correctly according to the manufacturer's instructions. Incorrect installation can lead to improper brake function and safety hazards.
4. Lubrication:
- Apply a small amount of high-temperature brake grease to the contact points between the brake shoes and the backing plate to reduce friction and wear.
Using an accessory kit when servicing drum brakes helps ensure that the entire braking system functions smoothly and reliably, contributing to the overall safety and performance of the vehicle.
