Brake System Concerns
The Benelli Tnt 135 is a great bike, but it can have brake issues. Understanding these concerns helps ensure your bike’s safety and performance. This section covers two main brake system concerns: spongy brakes and brake pad wear.
Spongy Brakes
Spongy brakes are a common issue with many bikes. This means the brake lever feels soft when you press it. This can be dangerous as it affects braking performance. There are a few reasons this can happen:
- Air in the brake lines: Air bubbles reduce the efficiency of the brake fluid.
- Worn brake fluid: Old fluid can lose its effectiveness.
- Brake line issues: Damaged lines can cause leaks or loss of pressure.
To fix spongy brakes, start by bleeding the brake lines. This removes any air bubbles. Next, check the brake fluid. Replace it if it’s old or contaminated. Lastly, inspect the brake lines for any visible damage or leaks.
Brake Pad Wear
Brake pads wear out over time. They need to be checked regularly. Worn brake pads can reduce braking power. Signs of worn brake pads include:
- Squealing noise: This indicates the pads are thin.
- Reduced braking power: The bike takes longer to stop.
- Visible wear: You can see the pads are thin.
To check brake pads, remove the wheel and inspect the pads. Use a flashlight for better visibility. If the pads are less than 3mm thick, replace them. Always use quality brake pads suitable for the Benelli Tnt 135.
Keeping your brake system in good condition ensures a safe riding experience. Regular checks and maintenance are key.
