4. Setup and Installation
The Tbest Universal Motorcycle Brake Fluid Reservoir is designed for installation on the pump of motorcycle brakes. It includes a black iron bracket for mounting.
Installation Steps:
- Prepare the Motorcycle: Ensure the motorcycle is stable and on a level surface. Turn off the engine.
- Identify Existing Reservoir: Locate the existing brake fluid reservoir on your motorcycle's master cylinder.
- Drain Old Fluid: Carefully drain the old brake fluid from the system according to your motorcycle's service manual. Use appropriate containers for disposal.
- Remove Old Reservoir: Detach and remove the old reservoir and its bracket.
- Position New Reservoir: Position the new Tbest reservoir with its black iron bracket in the desired location. Ensure it is level and secure, allowing for proper fluid level visibility.
- Attach to Master Cylinder: Connect the reservoir to the master cylinder using appropriate fittings. These are typically reused from the original setup or purchased separately if needed.
- Secure Bracket: Secure the bracket to the motorcycle frame or handlebars using the provided bolt. Ensure all connections are tight but do not overtighten.
- Fill with Fluid: Fill the reservoir with the correct type of brake fluid (DOT3 or DOT4, refer to your motorcycle's manual) up to the 'UPPER' level mark indicated on the reservoir.
- Bleed Brake System: Bleed the brake system thoroughly to remove any air, following your motorcycle's service manual procedures. This is a critical step for proper brake function.
- Final Check: Check for leaks around all connections and ensure proper brake lever feel and operation before riding.

Note: Professional installation is highly recommended to ensure correct and safe operation of the brake system.
5. Operating Instructions
Once installed and the brake system is properly bled, the Tbest Universal Motorcycle Brake Fluid Reservoir operates automatically as an integral part of your motorcycle's hydraulic brake system.
- Fluid Level Monitoring: Ensure the fluid level remains between the 'UPPER' and 'LOWER' marks visible on the reservoir. These marks indicate the safe operating range for brake fluid.
- Normal Operation: The reservoir will supply brake fluid to the master cylinder as needed during braking.

6. Maintenance
Regular maintenance is crucial for the safe and effective operation of your motorcycle's brake system.
- Regular Fluid Level Checks: Periodically inspect the brake fluid level in the reservoir. It should always be between the 'UPPER' and 'LOWER' indicators. Check more frequently if you notice any changes in braking performance.
- Fluid Replacement: Brake fluid absorbs moisture over time, which can reduce braking performance and lead to corrosion within the brake system. Consult your motorcycle's service manual for recommended brake fluid replacement intervals. Typically, brake fluid should be replaced every 1-2 years.
- Inspection for Leaks: Regularly check the reservoir, hoses, and connections for any signs of leaks. Look for fluid stains or drips. Address any leaks immediately.
- Cleaning: Keep the exterior of the reservoir clean to easily monitor fluid levels and detect any issues. Use a clean cloth and avoid harsh chemicals that could damage the plastic.
7. Troubleshooting
This section addresses common issues you might encounter with the brake fluid reservoir.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Brake Fluid Level | Leak in the brake system; normal wear and tear of brake pads. | Check for leaks in the brake lines, calipers, and master cylinder. Top up with the correct brake fluid type (DOT3 or DOT4). If brake pads are worn, replace them. |
| Spongy Brake Lever | Air in the brake system. | The brake system needs to be bled to remove air bubbles. Refer to your motorcycle's service manual or seek professional assistance. |
| Oil Leak from Reservoir | Loose connections; damaged reservoir or cap seal. | Ensure all connections to the reservoir are tight. Inspect the reservoir for cracks or damage, and check the cap seal for proper seating. Replace the reservoir if damaged. |
