Shimano s BR-M8220/BL-M8200 XT 4 Pot Disc Brake Kit delivers fast, controlled, and consistent braking with full on-the-fly adjustability for trail and enduro use. Its rigid lever design, powerful calipers, and advanced Servo-Wave system work together to deliver sharp engagement and precise modulation under pressure. Engineered for riders who need confidence and control on technical descents, this kit is designed to perform in demanding terrain without compromise.Key Features and Benefits:Short stroke Servo-Wave with SIL-TEC roller: This feature shortens the lever s free stroke while boosting braking force. It creates quicker pad engagement and a smoother, more controlled lever feel, allowing you to brake later and more confidently in steep or high-speed terrain.Dual-diameter 4 piston caliper design: The caliper uses two different piston sizes to balance power and control. This results in strong initial bite without harshness, giving better modulation when conditions change mid-trail.Forged two-piece caliper body: The forged construction increases caliper stiffness while keeping weight low. This reduces flex under heavy braking, ensuring power is applied directly and predictably when needed most.Braced master cylinder with second contact point: A structural brace supports the lever body under load. This increases rigidity at the pivot, improving brake response and helping maintain a consistent lever feel under stress.Hinged clamp and tool-free reach adjustment: The hinged design simplifies fitting, while reach adjust allows quick setup without tools. Together, they ensure fast installation and a dialled cockpit feel that suits your hand size and riding style.Low Viscosity Oil brake fluid: Specifically designed for a stable response across a wide temperature range. This keeps the braking consistent in both cold descents and hot, sustained braking, reducing fade and lever inconsistency.This brake kit is built for riders who demand precision and power when terrain gets rough. With its Servo-Wave system, 4-piston control, and ergonomic lever setup, it supports hard braking with minimal effort, even on long descents or under load. The solid construction and tuning options offer reliable performance and adaptability for aggressive trail and enduro riding.Equip your bike with a brake system that matches your riding intensity. With Shimano s proven design and customisable setup, this kit is ready to meet the demands of technical riding with confidence and consistency.Kit also contains pads, spare olives and insert should you wish to adjust the length of the cuttable hoses. Hose length 1700mm or 1000mm. Adapters and rotors not included.
