Brake Caliper Piston SIZE 35mm diameter x 29mm height › 90135209910
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 356C 1963-65
Restore safe and dependable braking performance with this OE Match Replacement Brake Caliper Piston, measuring 35mm diameter x 29mm height, manufactured as a direct replacement. Produced to OE-style specifications, this precision-engineered caliper piston is designed to replace worn, corroded, or damaged original pistons during brake caliper overhaul and restoration.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 356C 1963-65
The brake caliper piston converts hydraulic brake pressure into mechanical force, pressing the brake pads evenly against the brake disc to provide consistent stopping power. Over time, moisture, contaminated brake fluid, corrosion, or damaged seals can cause the piston to seize, stick, or wear, resulting in reduced braking efficiency and uneven brake pad wear. This OE Match replacement restores smooth caliper operation and reliable 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 vital component of the hydraulic braking system. A worn, corroded, or seized piston can reduce braking efficiency, cause uneven braking, increase brake component wear, and compromise vehicle safety.
- Replacing a damaged piston restores smooth hydraulic operation, even brake pad contact, and dependable stopping performance. 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 classic Porsche restoration.
