Features:

• Guarantees proper performance throughout the lifetime of the caliper
• Made from high-quality phenolic resin
• Carefully tested to ensure a precise fit, high quality, and excellent performance

Made from premium phenolic resin and manufactured to the most stringent OE requirements, this caliper piston is resistant to corrosion and rust while ensuring excellent performance. Phenolic pistons are also lighter than steel pistons and have superior heat insulating properties, which helps prevent heat from being transferred to the brake fluid and causing a spongy pedal.
