3. Mounting Brackets Mounting Brackets are used to hold the Caliper in place. Other than keeping the surface clean and free of rust and road grime, there is very little to be done with this part
4. Rotors Rotors are metal discs supported by the suspension. The Calipers clamp on to them to slow their rotation, and then slow or stop the car
6. Vented Rotors Vented Rotors have Fins in the spaces between their machined surfaces. These spaces allow air to pass through, which helps carry heat away.
7. Nonvented Rotor Non Vented Rotors are used on smaller vehicles, and have no cooling fins
9. Rotor Repair We will get back to these Rotors later concerning what you can do as a repair on them.
10. Calipers Calipers are the housings that contain the Pistons and the Brake Pads. The Calipers are connected to the Hydraulic System, and hold the brake pads to the Rotor
17. Operation Piston applies pressure to Inboard pad. As the pad contacts the rotor, the caliper slides along the pins, pulling the outboard pad into contact. Caliper Rotor Piston Brake Pads Brake Line
21. Piston The Piston surface should be smooth and clean. This one is pitted, and needs replaced.

23. Caliper Slides Notice where the brake pads and calipers slide on the pin and the mount
24. Caliper slides Since parts need to slide, these areas should be clean of dirt and rust,
25. Cleaning Caliper With the caliper off, I would use a wire brush to clean the rust off, then use a brake cleaning solvent to wash the sliding area.
26. Wear Indicators Brake pads wear, and most people never check them. So, something was put on the pads to make a noise, since most people will have a noise checked out.
