Semi Metallic brake pads 1.Quiet braking 2.More initial disc bite contact. 3.Shorter break-in brake reflection period. 4.Contact disc rotor softly. 5.Low noise and good hydraulic braking performance. 6.Under high temperature conditions, it has excellent heat dissipation, high temperature resistance, and strong braking force. When do you replace your pads? We recommends not letting the pad's braking material wear thinner than 0.9 mm, but it certainly doesn't hurt to replace them sooner than that. My personal rule is to not let the pads get any thinner than the thickness than a dime. You'll also know that they have worn much too thin once the pad spring starts making contact with the rotor. If that is happening you know that you should have replaced the brake pads a while back! How to choose bicycle disc brake pads? -You are heavy -You ride downhill -The conditions are wet, muddy, etc. -Your riding is less hard on brakes i.e. dirt jump/street, XC, etc.
