What Our Gearhead(R) Experts Are Saying: "I put the M8220 brake upgrade kit on my trail bike and it was a total game changer. The 4-piston power is unreal, and the modulation from the BL-M8200 levers is smooth and consistent. The new pad design solved the annoying rattle too-super quiet and locked-in feel. Zero regrets with this upgrade." When terrain gets steeper, trails get rougher, and speed picks up, we count on the DEORE XT M8220 Brake Upgrade Kit to give us the confidence and control to keep pushing. Designed for trail and enduro riders who demand strong, consistent braking, this complete kit pairs Shimano's powerful BR-M8220 4-piston calipers with their refined BL-M8200 levers for a full-system upgrade that doesn't miss a detail. The 4-piston calipers deliver downhill-level braking force and modulation, while low-viscosity mineral oil ensures performance stays consistent across long descents and extreme temperatures. The levers' SERVO WAVE cam delivers fast engagement and precise control, with tool-free reach adjust to fine-tune fit. With a rattle-free pad and mount design, the M8220 kit adds silence and performance in one simple, trail-proven package.
