    Piston, brake caliper

    The Piston, brake caliper (D025138) applies hydraulic force to the brake pads, ensuring strong and reliable braking performance. Replacing a worn piston restores smooth caliper function and consistent stopping power. Use Porza’s smart search to find the correct piston.

    FAQ

    A brake caliper piston is a cylindrical component inside the brake caliper that converts hydraulic pressure into mechanical force. When the brake pedal is pressed, brake fluid pushes the piston outward, pressing the brake pads against the disc to create friction and slow the vehicle. The piston then retracts slightly after braking to maintain proper clearance between the pads and the disc.

    Key specifications include piston diameter, height, material type, and surface finish. Pistons are commonly made from steel, aluminum, or phenolic (composite) materials. Steel pistons offer strength, while phenolic pistons provide better heat insulation. Surface treatments such as chrome plating or anodizing improve corrosion resistance and reduce friction. The piston must withstand high temperatures (often exceeding 200°C) and hydraulic pressure while maintaining dimensional stability.

    Replacement is necessary when the piston is corroded, pitted, seized, or causing brake fluid leaks. Symptoms include uneven braking, sticking calipers, or reduced braking performance. Pistons are often replaced during caliper overhaul along with seals and dust boots to restore proper function.

    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the piston matches the exact diameter and design required for your brake caliper, minimizing the risk of incorrect fitment.

    Porza supplies high-quality brake components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows quick access to essential parts for both professional workshops and individual users, with reliable availability and service.

    If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a secure and risk-free purchasing experience.
