Setup
- Unpack the Bottle: Carefully remove the brake bleeding bottle and its components from the packaging. Inspect for any damage.
- Prepare the Hose: Ensure the clear hose is securely attached to the bottle's inlet port. The other end of the hose will connect to the vehicle's bleed nipple.
- Positioning: Place the bottle on a stable, flat surface near the brake caliper or wheel cylinder you intend to bleed. The wide base provides added stability. Utilize the two hanging hooks if a suitable hanging point is available to prevent accidental spills.
- Check Vent: Ensure the vent located in the lid is clear and functional to allow air displacement during fluid collection.
Operating Instructions
Follow these steps for effective brake bleeding:
- Prepare the Vehicle: Refer to your vehicle's service manual for specific brake bleeding procedures, including the correct bleeding sequence for each wheel. Ensure the brake fluid reservoir is topped up.
- Connect the Hose: Attach the clear hose from the Sealey VS0212 bottle securely to the brake bleed nipple on the caliper or wheel cylinder.
- Open Bleed Nipple: Using the appropriate wrench, carefully open the bleed nipple.
- Pump Brake Pedal: Have an assistant slowly depress the brake pedal fully and hold it.
- Observe Fluid Flow: As the pedal is depressed, old brake fluid and air bubbles will flow through the clear hose into the collection bottle. The clear hose allows you to evaluate the condition of the fluid and the presence of air.
- Close Bleed Nipple: While the brake pedal is still depressed, close the bleed nipple.
- Release Brake Pedal: Once the nipple is closed, the assistant can release the brake pedal. The integrated one-way valve in the bottle helps prevent air from re-entering the system when the pedal is released.
- Repeat: Repeat steps 3-7 until clean, bubble-free fluid flows from the bleed nipple. Regularly check and top up the vehicle's brake fluid reservoir to prevent air from entering the master cylinder.
- Emptying: Once bleeding is complete, use the drain cap for simple and clean emptying of the old brake fluid into a suitable container for recycling.
Maintenance
Proper maintenance ensures the longevity and performance of your brake bleeding bottle.
- Cleaning: After each use, empty the collected brake fluid and clean the bottle thoroughly. The product care instructions specify Hand Wash Only. Use appropriate cleaning agents for brake fluid residue.
- Inspection: Regularly inspect the hose for cracks or damage and the one-way valve for proper function. Replace components if necessary.
- Storage: Store the bottle in a clean, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
If you encounter issues during brake bleeding, consider the following:
- Air Re-entering System: The Sealey VS0212 is designed with a one-way valve to minimize this. Ensure the hose connection to the bleed nipple is tight and the nipple is closed before the brake pedal is released.
- Slow Fluid Flow: Check for blockages in the hose or bleed nipple. Ensure the brake fluid reservoir is not empty.
- Leaks: Verify all connections are secure. Inspect the hose and bottle for any cracks or damage.
- Persistent Air Bubbles: This may indicate a larger issue with the brake system or an incomplete bleeding process. Consult your vehicle's service manual or a qualified mechanic.
