【4- 】Zoom HB-876 Hydraulic Disc Set Features with a 4- pistons, which makes the dual-side breaking force evenly and also increase the breaking force by 30% and the pads lifetime by 150%. levers are made of high-end alloy, suitable for mountain bikes, electric , scooter, folding , etc

【Massive Stopping Power】Compared to traditional brakes, hydraulic systems can convert smaller forces into larger braking forces. Due to the characteristic of fluid transmitting , the operation of hydraulic brakes is smoother and more precise. Hydraulic systems can transmit braking forces over longer distances, reducing response time. Ideal for trail riding, downhill, choppy mountain, snow, beach, flat road etc

【 Brakes Size】The front hose length is 850mm (33.50in), and the rear hose length is 1450mm (57.09in). Please double-check your ’s routing and frame size before purchasing to ensure the hose lengths are a fit for your setup

【Quiet Braking】MTB hydraulic brakes adopt integrated hydraulic cylinder to oil leakage. The pad is made of -metal composite pads, which not only not rotor, but also not make any noise when braking

【Installation Instructions】Make sure the calipers and pads correctly fitted to the hub and aligned with the disc. Adjust the clearance and fine tune the adjustment screws to ensure good braking without clicking. Exhaust the hydraulic disc system to maintain optimum performance. Pull the handle to test if the brakes are contacting the disc to make sure the braking effect is normal
