•  Position on Vehicle: Front axle brake calipers, service train of the front brake system.

•  Applications: Ideal when the original caliper pistons or seals have been serviced, when you observe brake lever/root pressure changes, when brake fluid contamination has occurred or during a full caliper rebuild.

The sealing components within a brake caliper are critical to safe and effective braking performance. Worn or damaged seals can lead to piston sticking, brake drag, uneven pad wear, reduced braking efficiency or fluid loss. Replacing with a correctly specified rebuild kit restores hydraulic integrity, ensures smooth piston operation and helps maintain your 911’s original braking feel.

When and why to replace:
• Caliper pistons are sticking or moving unevenly.
• Visible damage to dust boots or signs of fluid leakage around the caliper.
• Uneven pad wear or brake performance inconsistency.
• During brake pad or rotor replacement when calipers are open.
• High-mileage vehicles or cars where original seals have not been replaced.
