Durable materials: machined titanium bodies with rubber seals combine high strength and corrosion resistance (titanium) with reliable sealing and vibration damping (rubber) for long-lasting brake lever performance. Restores and stabilizes braking: designed to replace worn or damaged brake lever pistons, helping restore consistent lever feel, reduce free play, and maintain modulation under repeated use. Exact fit for models M8000, M7000, M785: engineered to integrate seamlessly with the specified brake lever assemblies for straightforward replacement and dependable function. Built for mountain biking conditions: constructed to withstand mud, water, impacts, and frequent use typical of off-road riding while maintaining reliable operation. Simple installation: install quickly using the included instructions; no special tools required for most standard maintenance tasks. Secure fit without complex adjustments. Maintenance-friendly: rubber sealing reduces fluid leakage risk and keeps contaminants out of the piston bore, extending service intervals and protecting internal components. Typical applications Routine service: replace old or worn pistons during a brake rebuild to restore lever travel and braking consistency. Trail repair or upgrade: swap in these pistons before a multiday ride or after a hard season to increase component durability without major overhaul. Preventative maintenance: install during scheduled maintenance to reduce the likelihood of leaks and maintain predictable braking in wet, muddy, or dusty conditions. What you get Brake lever pistons made of titanium and rubber, sized and configured to fit models M8000, M7000, and M785. Clear installation instructions for quick, no-fuss replacement. Compatibility note Specifically compatible with M8000, M7000, and M785 lever assemblies. Verify your lever model before purchase to ensure correct fit.
