Why do rotors rust?
Rust is a fact of life for rotors because the best metal for them is highly susceptible to corrosion. It is an issue for car manufacturers - the cars sit on the lot for months waiting to be sold and the rotor rusts slightly everywhere but where the brake pad seals moisture out.
Can cast iron rotors rust?
As you probably well know, bare iron or steel will rust very easily. The cast iron of this rotor is no exception. The apparent smoothness of the side of your rotor we can see leads me to believe you have plenty of pad left at least on this side (the inside may be a different story).
Do brakes get hot?
For the rust which is present, it is easily explained. When brakes are used they get very hot. Except for a few exterior coatings which prevent this, most coatings/paint heat up and peel off, leaving a nice fresh surface of bare metal behind (even more so if there's no coating in the first place).
When should brake calipers be inspected?
Whenever any brake work is being performed on your car, whether that's pads, rotors, or a fluid flush, the calipers should be thoroughly inspected for any possible needs. This is the most opportune time to check for corrosion, leaks, or any signs of damage.
What is brake caliper?
Brake calipers, found only on disc brake systems, house pistons which use the force of hydraulic brake fluid to stop the vehicle. More specifically, those pistons squeeze brake pads against rotating disc brake rotors - creating the friction necessary for scrubbing off speed.
How do floating calipers work?
As we mentioned before, "floating" calipers slide on guide pins from side to side over the brake rotor. As caliper pistons move outward, the inboard pad contacts the rotor first, causing the caliper to slide over until the outer pad makes contact with the rotor.
Why do brake pads wear unevenly?
As a result, brake pads will wear unevenly if proper contact isn't made when a caliper hangs up. Excessive wear on outer brake pads may result if brakes stick instead of releasing freely, since that side won't be pulled away from contact with the rotor.
Why is it dangerous to have brake fluid leaks?
Of course, ANY brake fluid leakage is very dangerous, because if enough fluid leaks out, the vehicle may completely lose its hydraulic brake system.
Where does the floating caliper center?
When the brakes are released, the floating caliper self-centers itself over the middle of the rotor. Your vehicle owner manual may tell you whether your disc brake calipers are fixed or floating - but if not, a quick call to the manufacturer's headquarters should provide an answer.
