WebFriction. Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other. If two surfaces are in contact and moving ... WebWhen the brake pads push against a brake disc, the resulting friction generates heat that helps slow down the moving vehicle. The heat makes the smooth surfaces of a rotor malleable. Over time, this will lead to a bent or warped brake rotor. Brake pads pushing down on a warped rotor cause a brake shudder sensation in the steering wheel. cht allowanceWebFriction is a force, the resistance of motion when one object rubs against another. Whenever two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more ... ch tahir afzal
