How to the brake pads go back to their original position after they are squeezed by the caliper?

Question

when the caliper pushes the brake pads they squeeze the rotor to stop the car. after the caliper piston is released how are the brakes pulled apart? if they aren't pulled away from the rotor, does that mean the car is constantly stopping?

Answer 1

Some drag is still present at all times,the drag decreases as your foot backs off the brake pedal. Most pads can build up heat even if you haven't used the brake during a long drive. Use one foot when driving, coast to stops as much as possible and get your brakes checked every 6,000 miles if you drive more 12,000 miles a year. Most brake shops places will give you a "free inspection" so you know just how much wear your doing each year.

Answer 2

when you step on the brake pedal hydrolic pressure push the piston aganst pad when  release  there no presure the piston pull in

Answer 3

the master cylinder releases the pressure off of the piston in the caliper and the piston releases the pads away from the rotor.

Answer 4

They always rub on the rotor just a tiny bit. The caliper slides on the two pins so when pressure is released, the pads aren't actually pushing on the rotor.
