4. Configurazione e installazione
The brake cage bolt is used to manually release the spring brake. This procedure is typically performed when there is a loss of air pressure, or during maintenance to move a vehicle. Always ensure the vehicle is safely supported and secured before attempting any brake system work.
Precauzioni di sicurezza:
- Indossare sempre dispositivi di protezione individuale (DPI) adeguati, tra cui occhiali e guanti di sicurezza.
- Ensure the vehicle is on a level surface and properly chocked to prevent unintended movement.
- Consult the vehicle's service manual for specific brake chamber procedures.
- Never work under a vehicle supported only by a jack. Use jack stands.
Fasi di installazione:
- Locate the Brake Chamber: Identify the spring brake chamber on the semi-truck or trailer.
- Identify the Release Hole: Most spring brake chambers have a designated hole for inserting a cage bolt. This hole is typically covered by a rubber plug or cap.
- Insert the Cage Bolt: Remove the plug/cap and insert the Srliya 800921 Brake Cage Bolt into the release hole.
- Thread and Tighten: Carefully thread the bolt into the internal mechanism of the spring brake chamber. Tighten the bolt until the spring brake is fully compressed and released. Do not overtighten.
- Secure the Bolt: Once the brake is released, the cage bolt can be fixed on the side of the brake chamber, if applicable, for repeated use or until the brake system is repaired.

5. Istruzioni per l'uso
The primary function of the Srliya 800921 Brake Cage Bolt is to manually release the spring brake. This is essential when the air brake system loses pressure, preventing the vehicle from moving. By caging the spring brake, the brake shoes are retracted, allowing the wheels to turn freely.
Procedure for Manual Brake Release:
- Ensure the vehicle is stable and secured.
- Access the spring brake chamber.
- Insert the cage bolt into the designated release port.
- Turn the cage bolt clockwise (typically) using an appropriate wrench or tool until the spring brake is fully compressed and the brake is released. You will feel resistance as the spring compresses.
- Once released, the vehicle can be moved. Remember to remove the cage bolt and restore the air brake system to proper working order before normal operation.
Note: The cage bolt is a temporary solution for moving a vehicle with a disabled air brake system. It is not intended for permanent operation. Always repair the underlying air brake issue promptly.
6. Manutenzione
The Srliya 800921 Brake Cage Bolt is designed for durability. Regular inspection and proper storage will ensure its longevity and readiness for use.
Manutenzione generale:
- Ispezione: Periodically inspect the bolt for signs of wear, corrosion, or damage to the threads.
- Pulizia: Keep the bolt clean and free from dirt, grease, and debris. Wipe it down after each use.
- Lubrificazione: A light coating of anti-seize compound or grease on the threads can prevent galling and ease insertion, especially in harsh environments.
- Magazzinaggio: Store the cage bolt in a dry, clean place to prevent rust and damage.
