Shimano XT M8120 4 Pot Hydraulic Brake Caliper. NO PADS OR BANJO BOLT. We have this product with pads and banjo bolt for £80.99. Shimano XT brakes need no introduction. Shimano XT 8100-series brakes are available in 2- and 4-piston versions (I tested the latter), and feature a painted aluminum body and ceramic pistons.
