4 Piston Hydraulic Disc Brake Team Series 2.3mm Rotors Full Meatal Pad

Brake(already filled with mineral oil)+screws. YH1 Oil needle Fit 74mm Post Mounting. Left lever for front wheel.

Right lever for rear wheel. Original Full Metal Pads-same as ZEE pads- MJ-01E/ D02S/ D03S. There are many benefits of full metal pads, greater braking force, stronger heat resistance, stable braking force regardless of sunny or rainy days, But because it is harder, it takes a period of running-in before it can work normally. At the beginning, the braking force is small which is normal, it will get bigger and bigger.

And a slight braking sound is normal for metal pads. Upgrade 4x16mm pistons + 4x11mm Thermal insulation phenolic compound caliper structure, it's make the brake pads more balanced and create more brake force. The piston is made of aluminum alloy, it's strong and has excellent heat resistance. Required small fingers strength, but big brake force, feel relaxed in the long downhill, Brake performance is not affected by weather changes, still stable, not easy to be affected by soil or rain. ZTTO Cylinder Ratio and Brake Linearity. The brake equired strength is small, in the long downhill, fingers and arms are not easy to feel tired. Brake performance is not affected by weather changes, still stable, not easy to be affected by soil or rain. So you don't need to remove the grips and shifter befroe install the brake. Left front brake hose length :850mm Right rear brake hose length:1750mm due to there is a part of hose inside the brake, so ±30mm is normal.
