The Seal, brake caliper piston (2.40120) restores proper brake caliper function by replacing worn seals, boots, and internal components. Using a repair kit helps ensure smooth piston movement, consistent braking pressure, and longer caliper lifespan.
With Porza’s smart search, you can easily find the correct brake caliper repair kit for your vehicle using your license plate, VIN, or detailed vehicle information. Choose Porza for quality parts, fast delivery, and dependable service.
A brake caliper piston seal is a critical sealing component located inside the caliper bore. It ensures hydraulic pressure is maintained when braking and prevents brake fluid leakage around the piston. Additionally, the seal has an elastic deformation function that slightly retracts the piston after braking, helping the brake pads release from the disc and reducing drag and wear.
Key specifications include inner diameter, groove fitment, and material composition. Most seals are made from EPDM rubber, which is resistant to brake fluid (DOT 3, DOT 4, DOT 5.1) and high temperatures typically exceeding 150–200°C. The seal must meet strict tolerances to ensure proper pressure retention and piston movement, and it should also offer resistance to aging, moisture, and chemical exposure.
Replacement is necessary when there are signs of brake fluid leakage, reduced braking performance, sticking pistons, or visible wear during caliper overhaul. Seals are commonly replaced during brake caliper rebuilding to restore proper hydraulic function and prevent future failures.
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 seal matches the exact dimensions and design of your brake caliper, minimizing the risk of incorrect fitment.
