Original Full Metal Pads-same as ZEE pads- MJ-01F/ 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.

4 Metal Pistons

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.
