Lewis LH4: Premium CNC Braking Performance

The Lewis LH4 Axial Cylinder Brake brings boutique-level CNC quality to the trail at an accessible price point. Engineered for Downhill, Enduro, and All-Mountain riding, the LH4 strikes the perfect balance between raw stopping power and refined modulation.

Constructed from CNC-machined 7075 T6 Aluminum, the LH4 is significantly stiffer than standard cast brakes. This rigidity ensures that every millimeter of lever pull translates directly into braking force, giving you confidence on the steepest descents.

Key Features:

• Dual-Diameter Piston Technology: The caliper utilizes an asymmetric 4-piston layout (2 x 14mm and 2 x 17mm). The smaller pistons engage slightly earlier to ensure smooth initial modulation, while the larger pistons provide the raw clamping force required for maximum stopping power.
  
  
• Tool-Free Dual Adjustment: Fine-tune your cockpit in seconds. The LH4 features patented external dials for Lever Reach (Tool-free) and Bite Point (Hex key needed, thumb tool included) adjustment, allowing you to customize exactly where the lever sits and where the power kicks in.
  
  
• Ultra-Smooth Lever Feel: Unlike budget brakes that use bushings, the LH4 lever pivots on precision sealed bearings. This results in a frictionless, feather-light lever action that reduces hand fatigue on long runs.
  
  
• Robust Build Quality: Features split clamps for easy installation and Kevlar-reinforced hoses to prevent hydraulic expansion and loss of power under heavy load.

Mechanic's Note (Pad Compatibility): The Lewis LH4 is designed to use Hope Tech 3 E4 brake pads. This large pad shape provides excellent heat management and modulation.

Configuration:

These brakes are sold in the standard configuration:

• Left Lever: Front Brake
• Right Lever: Rear Brake

Note: The levers feature a "Flip-Flop" design. If you ride "Moto Style" (Right/Front), you can easily unbolt and swap the hoses to reverse the configuration.
