Titanium Brake Lever Piston | Shimano M8000/M7000/M785
Titanium brake lever piston | Brake fluid, sweat & corrosion resistant
Shimano M8000 / M7000 / M785 | Sold per piece | Includes 2x O-Ring
Shimano hydraulic brakes are excellent until the piston corrodes and the lever jams.
This titanium replacement piston is ~40% lighter than the stock part, resistant to brake fluid and corrosion. A small part with a disproportionate impact on brake reliability.
The root cause of lever jamming on these Shimano brakes is corrosion on the stock piston.
Titanium does not corrode in contact with brake fluid, sweat, or moisture.
Physical Vapour Deposition (PVD) coating adds a hardened outer layer that resists scratching and surface wear.
Unlike conventional electroplating, PVD bonds at a molecular level. The finish won't flake, peel, or degrade in contact with brake fluid over time.
The piston is hot-stamp forged rather than machined from bar stock.
Forging aligns the grain structure of the titanium, producing a stronger and more fatigue-resistant component, better suited to the repeated hydraulic pressure cycles of a brake piston than a machined equivalent.
Titanium is significantly lighter than steel for the same strength.
Titanium is highly resistant to corrosion from DOT fluid, mineral oil, salt, and sweat — all of which the piston is exposed to in normal MTB use.
The PVD finish adds a further protective layer over the base titanium, keeping the piston functioning like new over the life of the brake.
Precision polished to a mirror finish.
Other components shown in product images are not included.
Installation involves opening the brake lever hydraulic system. If you are unfamiliar with hydraulic brake servicing, please seek assistance from a local bike shop.
Incorrect installation may affect brake performance and safety.
