      Frictional force is independent of the surface area of the two objects in contact.

            I thought friction did not depend on the surface area

                3:15 surface area has nothing to do with the friction

                    Just a quick correction increasing the surface area does not increasing your breaking power. The equation for a friction force is F=μN (friction force=coefficient of friction*normal force). Normal force would be how hard your squeezing the diskbreak, coefficient of friction is how much friction the two materials have when rubbing together, which when multiplied together gives you your total friction force. Surface area does not matter because as you increase it your N is spread out over that area giving you less friction per square inch. The larger surface area helps because there is more area to disperse the heat, not because it gives you more friction.

                      Rookie question. On disc brakes I understand how everything works with the floating caliper applying even pressure through hydraulics to both sides of the disc. My question is what causes the pads to retract? I see guys replacing pads and squeezing them right up to the disc. I know the piston applies the pressure for squeezing but what backs them off? I know they are extremely close to the rotor when no pressure is being applied so I'm guessing that the when the floating caliper with the spring loaded pins backs off the pressure, it just leaves the pads riding extremely close to the rotor if not barely touching which is why you almost always hear contact on any vehicle (motorcycle etc.) when just spin the wheel or roll it, like on my motorcycle. Thanks in advance for anyone's help.

                                                        Hey Science Garage, can you explain how regenerative brakes work? I have a BMW 328i and the manual says braking for longer is better than shorter distances, for energy recuperation. Also, it'd be nice to know why an engine at standby at a stoplight is better economy savings. Heck why don't you do a science garage on Hybrid Car's energy efficient qualities and characteristics!
