Built for riders who want maximum stopping power with minimal fuss, the SRAM DB4 Hydraulic Disc Brake & Lever Set delivers dependable, heavy-duty braking performance with a cleaner, quieter, and lower-maintenance mineral oil system. Sharing the same proven caliper architecture as SRAM’s DB8, the DB4 packs serious braking confidence for trail, enduro, eMTB, and aggressive all-mountain riding.

The stealth lever architecture routes hoses parallel to the bars for a cleaner cockpit setup, especially when paired with modern mechanical drivetrains. Ergonomic forged aluminum levers feature tool-adjustable reach so you can fine-tune feel and comfort, while 4-piston forged aluminum calipers provide consistent braking power when trails get steep, loose, or rowdy.

This exact Front + Rear set includes a 1000mm front brake and a 2000mm rear brake, is equipped with steel-backed organic pads for smooth modulation and quiet operation right out of the box. DIR (Post Mount) calipers provide broad compatibility across modern MTB frames and forks, with support for larger rotor sizes for improved braking power and heat management on aggressive descents.
