MEROCA M800 Mountain Bike Hydraulic Disc Brakes Hydraulic Bike Brakes Front 800mm and Rear 1400mm with PM Adapter for 160mm Rotor

Dominate Every Trail with Professional-Grade Stopping PowerEngineered for demanding mountain bikers, MEROCA's hydraulic disc brake system combines race-proven dual-piston technology with user-friendly features for uncompromised control.Why Riders Choose This Brake Set:Synchronized Dual-Piston Calipers: Twin pistons clamp the rotor symmetrically, eliminating uneven pad wear and rotor warping. The self-adjusting mechanism maintains consistent pad-to-rotor clearance for zero-drag pedaling.Integrated Oil Cylinder Advantage: Our patented one-piece reservoir amplifies hydraulic pressure, translating 30% less lever effort into stronger braking versus conventional systems—crucial when navigating rock gardens or switchbacks.All-Weather Reliability: Mineral brake fluid maintains viscosity from -20°C to 200°C, while corrosion-resistant CNC aluminum calipers withstand mud, river crossings, and winter road salt.Installation Made Simple:Universal Compatibility: Fits 22.2mm handlebars and standard IS/A-post mounts (51mm B-pillar, 75mm A-pillar)Clear Safety Guidance: Protective spacers (included) prevent accidental piston engagement during setupPre-Bled Performance: Factory-tuned hydraulics require no bleeding—mount, align, and rideTechnical Specifications:Model: HD-M800 (Color: Black/Red/Pink/Blue/Gold/Purple)Rotor Compatibility: Front F160/F180, Rear R140/R160 (6-bolt)Lever: 3-finger design with tool-free contact point adjustmentWeight: Front 327g + Rear 311g = 638g/setNote: Always remove caliper spacers BEFORE squeezing levers to avoid oil seal damage.

• Dual-Piston Precision: Synchronous dual-piston braking technology applies equal force on both sides of the rotor, delivering instant stopping power, smooth modulation, and automatic pad retraction for wobble-free control on mountain trails
• Effortless One-Finger Control: Integrated oil cylinder design generates higher pressure with less lever input. Achieve confident braking with a light squeeze—perfect for long downhill rides and technical terrain
• Upgraded Resin Brake Pads: High-friction resin compound provides superior stopping power without damaging rotors. Performs reliably in wet/muddy conditions and resists heat fade during extended braking
• Complete MTB Brake Kit: Includes front brake (327g) with 800mm hose + rear brake (311g) with 1400mm hose. Pre-bled and pre-adjusted for standard 51mm/75mm mounts. Ready to install on 160mm 6-bolt rotors
• Rider-Focused Engineering: Features 3-finger ergonomic levers with reach adjustment, mineral oil fluid for stable high-temp performance, and safety lock pins to prevent leaks during installation. Total set weight: 638g
