Lewis LHP-U4 4 Piston Hydraulic Bicycle Disc Brake Kit

The Lewis LHP-U4 Axial Cylinder 4-Piston Hydraulic Disc Brake is engineered for high-performance mountain biking, particularly downhill, enduro, and all-mountain disciplines. Constructed from CNC-machined 7075 T6 aluminium, it features stainless steel pistons with insulating layers and independent cooling fins to manage heat buildup during intense rides.

The brake lever boasts a new leverage ratio adjustment system, combined with tool-free lever reach and bite point customisation, allowing riders to achieve a perfectly tailored braking feel. Compatible with sintered and semi-metallic pads, it also incorporates anti-leak technology for consistent performance. Lightweight and available in black and silver, the LHP-U4 ensures durability, heat management, and powerful braking performance.

Lewis recommends using the Lewis  PM-PM+20-A caliper mount adapter. When testing both the Lewis  PM-PM+20-A and PM-PM+20 20mm post mount adapters with our Fox 36 fork, we had no issues. If you have issues with fork compatibility, possibly try using the PM-PM+20-A adapter.
