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.

Brake Caliper Replacement Pistons for Brembo Calipers
Sold each
Restore the performance and reliability of your Porsche Brembo braking system with these OE Match Brake Caliper Replacement Pistons. Manufactured to original equipment specifications, these precision-engineered pistons are designed for rebuilding Brembo brake calipers fitted to a wide range of Porsche models.
Available in 28mm, 30mm, 32mm, 34mm, 36mm, 38mm, 40mm and 44mm outer diameters, every piston has an overall height of 32mm and is manufactured to deliver the correct fit, smooth operation and dependable sealing performance when used with new piston seals and dust boots.
Important: Please check the piston diameter required for your specific caliper before ordering. Many Brembo calipers use two different piston diameters within the same caliper to optimise braking performance. The sizes listed refer to the outer diameter (OD) of the piston.
What Does a Brake Caliper Piston Do?
The brake caliper piston is one of the most important components inside the braking system. Hydraulic brake fluid pressure pushes the piston forward, forcing the brake pad firmly against the brake disc to generate the friction required to slow or stop the vehicle.
Its primary functions include:
- Converting hydraulic pressure into braking force.
- Applying even pressure across the brake pads.
- Ensuring smooth and consistent piston movement.
- Maintaining balanced braking performance.
- Supporting Porsche ABS and stability control systems.
- Delivering precise pedal feel and braking response.
Correctly functioning pistons are essential for maintaining the powerful, progressive braking performance expected from Porsche Brembo calipers.
Why Do Brake Caliper Pistons Fail?
Brake caliper pistons operate in harsh conditions and are continually exposed to heat, moisture and brake dust. Over time they can become damaged or worn.
Common causes include:
- Corrosion caused by moisture ingress.
- Torn or damaged dust boots.
- Contaminated brake fluid.
- Surface pitting.
- Heat generated during heavy braking.
- Seized pistons caused by corrosion.
- Damage during previous repairs.
- High mileage and normal wear.
A damaged piston can prevent the caliper from operating correctly, leading to reduced braking performance and uneven brake pad wear.
Symptoms of a Worn or Damaged Caliper Piston
Common symptoms include:
- Sticking or seized brake calipers.
- Uneven brake pad wear.
- Vehicle pulling during braking.
- Reduced braking performance.
- Overheating brakes. Brake drag.
- Fluid leaks around the piston seal.
- Difficulty retracting the piston during servicing.
Replacing damaged pistons during a caliper overhaul restores smooth operation and reliable braking performance.
When Should Brake Caliper Pistons Be Replaced?
Replacement is recommended whenever:
- Corrosion or pitting is visible.
- Pistons become seized or difficult to move.
- The caliper is being rebuilt.
- Dust boots have failed allowing contamination.
- Brake fluid leaks occur around the piston.
- Uneven pad wear is caused by sticking pistons.
- Restoring older Brembo brake calipers.
- During preventative maintenance on ageing braking systems.
For the best results, new pistons should always be installed with new piston seals and dust protection boots.
