Product Information

Replacement Brake Caliper Piston, 30mm Diameter.
Restore safe and dependable braking performance with this OE Match Replacement Brake Caliper Piston, measuring 30mm diameter, manufactured as a direct replacement. Produced to OE-style specifications, this precision-machined caliper piston is designed to replace worn, corroded, or seized original pistons during brake caliper overhaul and restoration.

Fits:

Porsche 911 1978-1989 3.3L Turbo (930)

Diagram Ref No 41

The brake caliper piston converts hydraulic brake pressure into mechanical force, pushing the brake pads evenly against the brake disc to provide smooth, controlled braking. Over time, corrosion, contaminated brake fluid, damaged seals, or general wear can cause the piston to stick or seize, leading to reduced braking efficiency, uneven pad wear, and brake drag. This OE Match replacement restores correct caliper function and reliable braking performance, making it ideal for professional brake caliper refurbishment and classic Porsche restoration projects.

What This Product Does:

Converts hydraulic brake pressure into braking force.
Applies even pressure to the brake pads.
Restores smooth brake caliper operation.
Helps maintain consistent braking performance.
Reduces uneven brake pad wear.
Provides OE-style fit and dimensional accuracy.
Replaces worn, corroded, or seized original pistons.

Symptoms Of Wear Or Failure:

Seized or sticking brake caliper.
Uneven brake pad wear.
Brake pulling to one side.
Reduced braking performance.
Brake drag after releasing the brake pedal.
Corrosion or pitting on the piston surface.
Brake fluid leaks caused by damaged piston surfaces.
Overheating brake discs or brake pads.
Difficulty retracting the piston during servicing.
Age-related deterioration found during brake caliper rebuilds.

Why Replacement Matters:

The brake caliper piston is a critical component of the hydraulic braking system and plays a vital role in maintaining safe, consistent stopping performance. A worn, corroded, or seized piston can reduce braking efficiency, increase brake component wear, and compromise vehicle safety.
Replacing a damaged piston restores smooth hydraulic movement, even brake pad contact, and dependable braking performance. Manufactured to OE-style specifications, this OE Match replacement provides the correct fit, reliable operation, and long-lasting durability, making it an essential component for professional brake caliper refurbishment and preserving your Porsche's braking system to factory standards.
