Shimano Zee M640 Disc Brake

New Zee hydraulic disc brake systems are gravity rated with a Servo-Wave brake lever and new 4-piston ceramic disc brake caliper. System stiffness is tuned using Shimano’s high-power hose and shorter lever blade while ergonomics are perfected with a new pivot location and dimpled surface. ICE Tech brake pad and rotor options reduce heat in the system and maintain performance on the longest descents.

"With their consistent feel and trouble-free performance, Shimano's brakes have proven themselves time and time again. It's their Zee stoppers that really stand out in our minds, though, with them using the same four piston caliper and internals as the more expensive Saint setup, but forgoing both the tool free lever reach dial and the stroke adjust screw that doesn't seem to affect anything anyways. That means that they feel as if they could be used to slow down a runaway train if required to do so, and that they also sport the same great ergonomics that we've come to love from Shimano's brakes. Many of today's components feel as if they require near constant tinkering to keep working to their full potential, something that makes us really appreciate the trustworthy performance of the Zees. Isn't that how brakes should be?" - PinkBike Review
