Replacement Brake Caliper Piston, 48mm Diameter x 30mm Height.
Restore safe, consistent braking performance with this OE Match Replacement Brake Caliper Piston, measuring 48mm diameter x 30mm height, 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 refurbishment and restoration.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 356C 1963-65  

The brake caliper piston converts hydraulic brake pressure into mechanical force, pushing the brake pads evenly against the brake disc to provide controlled stopping power. Over time, exposure to moisture, contaminated brake fluid, corrosion, or deteriorated seals can cause the piston to stick or seize, resulting in reduced braking efficiency, uneven pad wear, and brake drag. This OE Match replacement restores smooth caliper operation and dependable braking performance, making it ideal for professional brake rebuilds 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 pedal.
• Corrosion or pitting on the piston surface.
• Brake fluid leaks caused by damaged piston surfaces.
• Overheating brake discs or pads.
• Difficulty retracting the piston during servicing.
• Age-related deterioration discovered during caliper overhaul.

Why Replacement Matters:

• The brake caliper piston is a critical component of the hydraulic braking system, directly affecting braking efficiency and vehicle safety. A corroded or seized piston can prevent even brake pad contact, increase brake wear, and reduce overall stopping performance.
• Replacing a damaged piston restores smooth hydraulic movement, reliable braking force, and even pad wear. Manufactured to OE-style specifications, this OE Match replacement provides the correct dimensions, precise fit, and long-lasting durability, making it an essential component for professional brake caliper refurbishment and maintaining your Porsche's braking system to factory standards.
