Shimano Deore XT Disc Brake Caliper Br-M8110 Flat Mount

Product Overview

The Shimano Deore XT M8110 is a 2-piston hydraulic disc brake caliper designed for flat-mount frame interfaces. It delivers reliable stopping power equivalent to post-mount systems while using a compact, lightweight design that integrates cleanly with modern frame geometry.

Key Features

• 2-Piston Design - Provides balanced braking force with predictable modulation across a range of rider weights and riding styles
• Flat Mount Interface - Mounts directly to flat-mount tabs on the frame; no adapters required; cleaner aesthetics and reduced unsprung weight
• Ice Technologies - Shimano's thermal management system that maintains consistent braking performance during extended descents or repeated hard stops
• Lightweight Construction - Minimizes rotational mass and contributes to overall bike weight reduction without compromising stopping power
• Tool-Free Adjustment - Simple leverage-based pad adjustment for maintenance and setup; no special tools needed for basic tuning

Technical Specifications

• Mount Type - Flat Mount (IS standard)
• Piston Count - 2 pistons
• Rotor Compatibility - 140 mm, 160 mm, 180 mm
• Pad Type - L04C Metal (included)
• Actuation - Hydraulic (mineral oil)
• Weight - Approximately 165-180 g (caliper body only)
• Brake Line - Shimano SM-BH59 or equivalent

Compatibility and Ideal Use Cases

• Frame Compatibility - Requires flat-mount disc brake tabs; standard on most modern hardtails and full-suspension bikes
• Rotor Selection - Pair with 160 mm or 180 mm rotor for trail riding; use 140 mm for lighter riders or shorter-travel bikes
• Ideal For - Trail, enduro, and all-mountain riding where reliable modulation and consistent stopping power are essential
• Not Recommended For - Post-mount frame geometries; dual-sport or gravity-focused setups that benefit from 4-piston calipers
• Maintenance - Metal pads provide durability in wet, muddy conditions; plan regular inspections during extended use
