Friction, for example the heating in brake discs and pads when slowing a vehicle
A brake rotor heating up would probably be caused by a sticky brake caliper or a collapsed brake hose.
One can purchase brake discs from a variety of stores. Stores such as AutoAnything, eBay, GSF Car Parts, Auto Parts Warehouse, and Walmart sell brake discs.
Depends on what kind of "discs" you're referring to... (compact discs? brake discs?)
there are brake shoes in the discs too . just remove the discs and you will see them. they are applied by a cable.
NO! No...no...no...! Do not put any grease on your brake discs, copper grease is used to put on the 'back' of the brake pads (not the part of the pad that comes into contact with the disc).
Jack up and block the car. Remove wheel, remove brake caliper. Rotor is now free.
Typically integral parking brakes are on rear disc braking systems. By activating the parking brake it adjusts the discs on the rear brakes. While the front discs are self adjusting, on the integral systems the rear discs are not self adjusting, thus the need for the integral parking brake system.
Only if they are defective.
replace front brake discs and pads.
The friction of braking makes brake drums and discs very hot.
On my 2007 Sonata I had to replace the brake pads and rotors at 57000 miles.
