Pistons are cylindrical components that create pressure within the hydraulic brake system of your bike. They push the brake pads against the wheel, allowing you to slow down or stop effectively. Properly functioning pistons are crucial for safe braking performance.

Piston bolts are fasteners that secure the pistons in place within the braking system. They ensure that the pistons operate correctly and maintain the integrity of the brake system. If piston bolts are loose or damaged, it can lead to brake failure, making them essential for your safety.

Seals are vital components that prevent the leakage of brake fluid in the hydraulic system. They help maintain pressure, ensuring that your brakes operate effectively. If seals are worn or damaged, it can lead to fluid loss and reduced braking performance.

A bleed screw is used to remove air bubbles from the brake lines, which can significantly reduce braking efficiency. Bleeding your brakes is an essential maintenance task that ensures optimal performance and safety while riding.

O-rings are circular rubber seals that prevent leaks in the braking system. They fit into grooves between components, creating a tight seal that keeps brake fluid contained and maintains pressure. Properly functioning O-rings are essential for reliable brake performance.

Signs that your bike's braking system may need maintenance include a spongy brake feel, reduced stopping power, fluid leaks, or unusual noises when braking. Regularly checking components like pistons, seals, and O-rings can help ensure your brakes are in top condition for safe riding.
