The Hope 16 mm Stainless Hybrid Piston Phenolic Insert is a genuine service component engineered to maintain precise, reliable braking performance in compatible Hope E4/V4 brake calipers. This hybrid piston combines a phenolic insert with a stainless steel outer to deliver optimal heat management, low friction, and long-lasting durability.

Phenolic materials help reduce heat transfer to brake fluid for more consistent modulation under load, while the stainless steel surface provides strength and wear resistance. Designed for a perfect fit with Hope’s braking systems that use 16 mm pistons, this insert is ideal for servicing worn parts or refreshing calipers to restore original braking feel.

• 16 mm diameter with stainless hybrid/phenolic construction
• For E4 / V4 Small
• Phenolic core for improved heat resistance and modulation
