Disc Brake Seal Kit for Nissan/Infiniti Calipers ️

This brake seal kit is a must-have when rebuilding a disc brake caliper. Its job is to keep brake fluid sealed inside the caliper bore while allowing the piston to move smoothly under hydraulic pressure. The square-cut seal flexes as you press the pedal, then helps the piston retract slightly when you release—reducing drag and heat.

Why this part is needed ✅

Over time, heat, moisture, and old fluid harden rubber seals. During pad replacement or caliper service, installing fresh seals restores correct pressure holding and reliable braking feel.

How it works ⚙️

The internal piston seal maintains pressure and controls piston return. The dust boot shields the piston from grit and water, preventing corrosion that can seize the caliper.

If the seals are worn or broken

You may get fluid leaks, a soft pedal, uneven braking, pulling to one side, sticking calipers, overheated pads/rotors, and longer stopping distances. Ignoring it can lead to brake failure.

Key benefits

• Restores proper hydraulic sealing
• Helps prevent caliper sticking
• Improves pedal feel and braking consistency
