The SRAM DB4 Hydraulic Disc Brake is a low-maintenance component that makes braking more controlled than ever. The new stealth lever architecture offers improved ergonomics and easy access to adjustments with left and right-specific levers. They route the hose parallel to the bar for seamless integration alongside mechanical Eagle Transmission shifters. It uses the same proven caliper design as the DB8 for consistent, powerful braking and features a split ring clamp. The DB4 is built for use with SRAMs Maxima Mineral Oil and Mineral Oil Bleed Kit. It accepts existing SRAM large brake pads for simple service and consistent performance. The SRAM DB4 Hydraulic Disc Brake is an affordable way to get the most control of your mountain bike.
