Titanium Alloy Replacement Piston for Brembo Calipers

silverlake

Titanium is a very poor conductor of heat, and reduces the heat transfer by approximately 90%
The standard aluminum brake pistons are light but very heat conductive which means the thermal energy from the brake pad transfers easily to the brake fluid.

The castellated contact edge promotes airflow into the piston cavity and reduces the contact surface with the pad and thus further decreases heat transfer to the brake fluid.

We designed using advanced engineering simulations (FEA) to achieve the same weight than their aluminum counterparts while maintaining superior structural strength.

As opposed to stainless steel pistons, our titanium alloy pieces weigh the same as the original aluminum pistons; and they will never corrode and damage the seals causing the caliper to leak.

Price is per pair of pistons

**Please check the piston diameter you need as some calipers take two different sizes. Sizes shown are the piston outer diameter (OD)

About Caliper Seals |Pistons

Porsche Caliper Seals & Pistons | Design911 Precision Hydraulic Components for Restoring Braking Power & Reliability

Caliper seals and pistons are vital hydraulic components in your Porsche’s braking system, ensuring smooth, consistent, and powerful brake performance. The piston transfers hydraulic pressure to the brake pads, while the seals maintain fluid integrity, preventing leaks and contamination. Over time, wear, heat, and moisture can compromise these parts — reducing braking efficiency and safety. Replacing caliper seals and pistons is essential for maintaining consistent pressure, pedal feel, and reliability.

At Design911, we offer a comprehensive range of caliper seals and pistons, engineered for precision fitment and durability. Each component is crafted from high-grade materials designed to resist corrosion, heat, and hydraulic fluid degradation. Perfect for servicing, performance upgrades, or complete caliper restoration, these components restore your Porsche’s braking response and ensure long-term dependability.

What Do Caliper Seals & Pistons Do?

These two components work together to create and maintain the hydraulic pressure that powers your Porsche’s braking system.

Core Functions:
• Pistons convert hydraulic pressure into clamping force against the brake pads.
• Seals prevent brake fluid leakage and maintain system pressure.
• Ensure smooth piston retraction for consistent pad contact.
• Protect against contaminants, moisture, and corrosion.
• Maintain balanced braking and pedal feel across all wheels.

High-quality seals and pistons ensure your Porsche delivers the stopping power, responsiveness, and control expected of its engineering pedigree.

Why Do Caliper Seals & Pistons Fail or Degrade?

Due to their exposure to heat, pressure, and environmental factors, these parts naturally deteriorate over time — especially in performance or high-mileage vehicles.

Common Causes of Failure Include:
• Seal wear or cracking from age and fluid degradation.
• Corrosion or pitting on pistons caused by moisture ingress.
• Brake fluid contamination leading to swelling or hardening.
• Heat damage from aggressive braking or track use.
• Improper installation or infrequent brake servicing.

When seals or pistons fail, symptoms such as fluid leaks, uneven braking, or sticking calipers can occur — compromising braking safety and performance.

Why Replace or Upgrade Your Porsche Caliper Seals & Pistons?

Replacing these components restores full hydraulic integrity and smooth brake operation. Design911’s premium-grade seals and pistons are designed for longevity, precision, and compatibility across Porsche models — ensuring reliability under road or track conditions.

Key Benefits:
• Restores consistent braking pressure and pedal feel.
• Prevents leaks and contamination in the hydraulic system.
• Improves caliper response and even brake pad wear.
• Manufactured from corrosion- and heat-resistant materials.
• Direct-fit design for fast, accurate installation.
• Ideal for restorations, rebuilds, or performance upgrades.

Design911’s Porsche caliper seals and pistons deliver unmatched performance and durability, helping your Porsche maintain the sharp braking response it was built for.

Highlights

• High-quality Porsche caliper seals and pistons for all models.
• Precision-engineered for hydraulic efficiency and longevity.
• Resistant to corrosion, high heat, and fluid degradation.
• Essential for brake caliper rebuilds or restorations.
• Improves pedal feel and braking consistency.
• Perfect for classic and modern Porsche vehicles.
