The Clarks C4 Hydraulic Disc Brake Set delivers competition-level four-piston braking with full adjustment and smooth modulation. Its rigid CNC-machined callipers, self-adjusting pistons and floating rotors provide firm, controlled braking. Built-in cooling features also help to keep performance stable on long or steep descents.Key Features and Benefits:Four-piston hydraulic system: Each calliper uses four pistons to apply even pressure across the brake pad. This creates strong braking force with controlled modulation, which helps you manage speed with greater accuracy.Four 16mm stainless steel pistons: The self-adjusting pistons move closer to the rotor as the pads wear. Machined piston heads reduce friction, which supports smooth movement and a consistent lever feel over time.Single-piece CNC-machined calliper: The rigid calliper body limits flex under heavy braking. This transfers more lever force to the pads and gives the brake a firm, direct response.Calliper heat management: Heat dissipation features are built into the calliper, while cooling fins help move heat away from the pads. This keeps braking more stable and can reduce pad wear during repeated use.Two-finger ergonomic lever: The lightweight lever uses a vented blade shaped for two-finger control. Its compact design gives you a secure grip while leaving more fingers around the handlebar.On-the-fly reach adjustment: A reach adjustment screw lets you change the lever position without removing the lever or using complex tools. This helps you set the brake for your hand size and preferred lever feel.Floating stainless steel rotors: The supplied rotors use stainless steel braking bands with aerospace-grade aluminium carriers. The floating design allows controlled movement as heat builds, which helps the rotor stay aligned during hard braking.Pre-bled mineral oil system: The brakes arrive filled with mineral oil and connected to the hoses. This reduces installation work and provides a ready-to-use system for mountain bikes, downhill bikes and e-bikes.The Clarks C4 provides the braking control needed for fast and demanding riding. Its four-piston callipers deliver strong force, while the adjustable levers help you find a natural hand position. Smooth modulation also makes it easier to apply the required amount of braking without a sudden response.Choose the Clarks C4 Hydraulic Disc Brake Set for adjustable four-piston braking, effective heat control and a complete pre-bled setup.
