Bleeding Edge 注油科技
With this new caliper fluid circuitry, the bleed port has been moved to the bottom of the caliper, and all four-piston bores can communicate. This way, during bleeding fluid naturally fills the caliper, resulting in an easier, more consistent bleed.

Contact Point Adjustment
Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. Its a quick and easy way to customize the feel of your brakes without having to move the pads. It's also a way to balance nee both brake levers to feel exactly the same.

Lever Pivot Bearings
Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one~finger feel.

Power Reserve Geometry
Your fingers pull in a straight line, but brake levers move in an arc. Bottom line: Your fingers typically want to slip off the ends of the levers as you pull. We designed all of our brakes with the industry's lowest X-Factor (that's the distance from the center of the handlebar to the center of the lever's pivot). That reduces the lever's inward travel, creating an arc that's closer to your finger's natural motion and more power is delivered to the brake lever. And, the cool part is, every SRAM and Avid brake lever has it.

S4 Light-weight 4-piston Caliper
The all-new S4 Caliper features four Machined and Moly-coated aluminum pistons for consistent rollback and easy set-up, Heatshield insulation and Bleeding Edge porting and adapter technology for easy bleeds.

Swinglink 擺動式連桿技術
Squeeze a SRAM brake lever and you notice it immediately. Less deadband. More positive engagement. A new cam system requires less lever throw to push the pads toward the rotor. That's great, but there's more to perfect braking performance than just power. You need control. Many brake systems minimize deadband but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, the leverage rate curve is flat and smooth, avoiding that "on/off" brake feel. Its the perfect balance of power and precision.

Timing Port Closure
A hydraulic brakes timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM's new timing port closure system features durable seals and an ultra-smooth cylinder bore finish producing dependable braking power and consistency.
